I am retrieving contacts from gmail using Google Data API. I have used below code:
string token = Request.QueryString["token"];
RequestSettings rs = new RequestSettings("myapp", token);
rs.AutoPaging = true;
List<string> lstEmails = new List<string>();
try
{
rs.AutoPaging = true;
ContactsRequest cr = new ContactsRequest(rs);
Feed<Contact> f = cr.GetContacts();
foreach (Contact e in f.Entries)
{
foreach (EMail email in e.Emails)
{
lstEmails.Add(email.Address);
}
}
}
catch
{
}
But it reads only 25 gmail contacts only
and it throws the following error:
Execution Failed: {https://www.google.com/m8/feeds/contacts/{email}/full?start-index=26&max-results=25}
but i want to get total contacts from gmail.

I have this Action method which act as an API end point inside our ASP.NET MVC-5, where it search for a username and return the username Phone number and Department from Active Directory (we are serializing the object using Newtonsoft.net):-
public ActionResult UsersInfo2()
{
DomainContext result = new DomainContext();
try
{
// create LDAP connection object
DirectoryEntry myLdapConnection = createDirectoryEntry();
string ADServerName = System.Web.Configuration.WebConfigurationManager.AppSettings["ADServerName"];
string ADusername = System.Web.Configuration.WebConfigurationManager.AppSettings["ADUserName"];
string ADpassword = System.Web.Configuration.WebConfigurationManager.AppSettings["ADPassword"];
using (var context = new DirectoryEntry("LDAP://mydomain.com:389/DC=mydomain,DC=com", ADusername, ADpassword))
using (var search = new DirectorySearcher(context))
{
// create search object which operates on LDAP connection object
// and set search object to only find the user specified
// DirectorySearcher search = new DirectorySearcher(myLdapConnection);
// search.PropertiesToLoad.Add("telephoneNumber");
search.Filter = "(&(objectClass=user)(sAMAccountName=test.test))";
SearchResult r = search.FindOne();
ResultPropertyCollection fields = r.Properties;
foreach (String ldapField in fields.PropertyNames)
{
// cycle through objects in each field e.g. group membership
// (for many fields there will only be one object such as name)
string temp;
// foreach (Object myCollection in fields[ldapField])
// {
// temp = String.Format("{0,-20} : {1}",
// ldapField, myCollection.ToString());
if (ldapField.ToLower() == "telephonenumber")
{
foreach (Object myCollection in fields[ldapField])
{
result.Telephone = myCollection.ToString();
}
}
else if (ldapField.ToLower() == "department")
{
foreach (Object myCollection in fields[ldapField])
{
result.Department = myCollection.ToString();
}
}
// }
}
string output = JsonConvert.SerializeObject(result);
return Json(output,JsonRequestBehavior.AllowGet);
}
}
catch (Exception e)
{
Console.WriteLine("Exception caught:\n\n" + e.ToString());
}
return View(result);
}
now the return JSON will be as follow:-
"\"DisplayName\":null,\"Telephone\":\"123123\",\"Department\":\"IT\",\"Name\":null,\"SamAccountName\":null,\"DistinguishedName\":null,\"UserPrincipalName\":null}"
but in our case we need to return a status code beside the return json data. for example inccase there is an exception we need to return an error code,also if we are able to get the user's info we need to pass succes code 200, and so on.. so how we can achieve this?
you can try something like this
var statusCode=200;
string output = JsonConvert.SerializeObject( new { result = result, StatusCode = statusCode);
but nobody usually do this. When users call API they can check status code that HTTP Client returns, using code like this
var response = await client.GetAsync(api);
//or
var response = await client.PutAsJsonAsync(api, data);
var statusCode = response.StatusCode.ToString();
//or usually
if (response.IsSuccessStatusCode) {...}
else {...}

Your code won't work against an OnPrem Public folder tree as EWS in Office365 won't proxy to an OnPrem Exchange Org (even if hybrid is setup). (Outlook MAPI is a little different and allows this via versa setup but in that case it never proxies either it just makes a different connection to that store and its all the Outlook client doing this).
Because your trying to use the client credentials oauth flow for that to work onPrem you must have setup hybrid modern authentication https://learn.microsoft.com/en-us/microsoft-365/enterprise/hybrid-modern-auth-overview?view=o365-worldwide. Then you need to acquire a token with an audience set to the local OnPrem endpoint. (this is usually just your onPrem ews endpoint's host name but it should be one of the service principal names configured in your hybrid auth setup Get-MsolServicePrincipal). So in your code you would change
var ewsScopes = new string[] { "https://outlook.office365.com/.default" };
to
var ewsScopes = new string[] { "https://OnPrem.whatever.com/.default" };
which will then give you a token with an audience set for the onprem server then you need to send the EWS request to that endpoint so change that eg
ewsClient.Url = new Uri("https://OnPrem.whatever.com/EWS/Exchange.asmx");
if Hybird Modern Auth is setup then you need to default back to use Integrated or Basic Authenticaiton.
I have below method to delete event in calendar:
public async Task<string> DeleteEventInCalendarAsync(TokenResponse token, string googleUserId, string calendarId, string eventId)
{
string result = null;
try
{
if (_calService == null)
{
_calService = GetCalService(token, googleUserId);
}
// Check if event exist
var eventResource = new EventsResource(_calService);
var erListRequest = eventResource.List(calendarId);
var eventsResponse = await erListRequest.ExecuteAsync().ConfigureAwait(false);
var existingEvent = eventsResponse.Items.FirstOrDefault(e => e.Id == eventId);
if (existingEvent != null)
{
var deleteRequest = new EventsResource.DeleteRequest(_calService, calendarId, eventId);
result = await deleteRequest.ExecuteAsync().ConfigureAwait(false);
}
}
catch (Exception exc)
{
result = null;
_logService.LogException(exc);
}
return result;
}
And I am getting error as follow -
Google.GoogleApiException Google.Apis.Requests.RequestError Not Found [404] Errors [ Message[Not Found] Location[ - ] Reason[notFound] Domain[global] ]
Can you help me understand why this error? Or where I can find the details about these error?
The error you are getting is due to the event's id you are passing doesn't exist or you are passing it in the wrong way. Following the .Net Quickstart I made a simple code example on how to pass the event's id to the Delete(string calendarId, string eventId) method from the Class Events
namespace CalendarQuickstart
{
class Program
{
// If modifying these scopes, delete your previously saved credentials
// at ~/.credentials/calendar-dotnet-quickstart.json
static string[] Scopes = { CalendarService.Scope.Calendar };
static string ApplicationName = "Google Calendar API .NET Quickstart";
static void Main(string[] args)
{
UserCredential credential;
using (var stream =
new FileStream("credentials.json", FileMode.Open, FileAccess.Read))
{
// The file token.json stores the user's access and refresh tokens, and is created
// automatically when the authorization flow completes for the first time.
string credPath = "token.json";
credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
GoogleClientSecrets.Load(stream).Secrets,
Scopes,
"user",
CancellationToken.None,
new FileDataStore(credPath, true)).Result;
Console.WriteLine("Credential file saved to: " + credPath);
}
// Create Google Calendar API service.
var service = new CalendarService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = ApplicationName,
});
// Define request.
EventsResource.ListRequest request = service.Events.List("primary");
// List events.
Events events = request.Execute();
Event existingEvent = events.Items.FirstOrDefault(e => e.Id == "your event id you want to get");
Console.WriteLine("Upcoming events:");
if (existingEvent != null)
{
Console.WriteLine("{0} {1}", existingEvent.Summary, existingEvent.Id);
string deleteEvent = service.Events.Delete("primary", existingEvent.Id).Execute();
}
else
{
Console.WriteLine("No upcoming events found.");
}
Console.Read();
}
}
}
Notice
I made this example in a synchronous syntax way for testing purposes in the console. After you test it and see how it works, you could adapt it to your code. Remember, make your you are passing the correct Id.

I'm wondering how I could get a list of members of an AD group.
Checking if an entered password of a user is correct works perfectly fine. For this I'm using Novell's Ldap.NetStandard:
private bool IsUserValid(string userName,string userPassword)
{
try{
using (var connection = new LdapConnection { SecureSocketLayer = false })
{
connection.Connect("test.local", LdapConnection.DEFAULT_PORT);
connection.Bind(userDn, userPassword);
if (connection.Bound)
{
return true;
}
}
}
catch (LdapException ex)
{
Console.WriteLine(ex.Massage);
}
return false;
}
What I want now is something like this:
bool isUserInGroup("testUser","testGroup");
The problem is I can't get my method working:
public bool IsUserMemberOfGroup(string userName,string groupName)
{
var ldapConn = GetConnection();
var searchBase = "";
var filter = $"(&(objectClass=group)(cn={groupName}))";
var search = ldapConn.Search(searchBase, LdapConnection.SCOPE_BASE, filter, null, false);
while (search.hasMore())
{
var nextEntry = search.next();
if (nextEntry.DN == userName)
return true;
}
return false;
}
What ever I'm doing, I'm not getting back any value from my Ldap.Search()...
Now there is an implementation of System.DirectoryServices.AccountManagement for .NET Core 2. It is available via nuget.
With this package you are able to things like that:
using (var principalContext = new PrincipalContext(ContextType.Domain, "YOUR AD DOMAIN"))
{
var domainUsers = new List<string>();
var userPrinciple = new UserPrincipal(principalContext);
// Performe search for Domain users
using (var searchResult = new PrincipalSearcher(userPrinciple))
{
foreach (var domainUser in searchResult.FindAll())
{
if (domainUser.DisplayName != null)
{
domainUsers.Add(domainUser.DisplayName);
}
}
}
}
This performs a search for the user in your domain.Nearly the same is possible for searching your group. The way I used to search my AD (description in my question) is now obsolet:
Checking if an entered password of a user is correct works perfectly

I host my web app which is written in .net mvc2 on amazon ec2. currrently use gmail smtp to send email. beacuse of google for startup email quota cant send more than 500 email a day. So decide to move amazon ses. How can use amazon ses with asp.net mvc2? How about configuration etc? Is email will send via gmail? because our email provider is gmail. etc.
Send Email via Amazon is a right decision. Because when you move to amazon you will immediately get 2000 email free per day which is greater than googla apps 500 emails quota a day.
Step by Step:
Go to http://aws.amazon.com/ses
and click Sign Up for Amazon SES.
To get your AWS access identifiers
verify your email address - email
which you will send email via. You
need perl packages installled on
your computer to test email
features.
include:amazonses.com to your dns record.
Step by step documentation.
http://docs.aws.amazon.com/ses/latest/DeveloperGuide/getting-started.html
There is a Amazon SES (Simple Email Service) C# Wrapper on codeplex you can use this wrapper to send emails.
Amazon SES C# Wrapper
Easiest way is to download the SDK via Nuget (package is called AWSSDK) or download the SDK from Amazon's site. The sdk download from their site has an example project that shows you how to call their API to send email. The only configuration is plugging in your api keys. The trickiest part is verifying your send address (and any test receipients) but their is an API call there too to send the test message. You will then need to log in and verify those email addresses. The email will be sent through Amazon (that is the whole point) but the from email address can be your gmail address.
#gandil I created this very simple code to send emails
using Amazon;
using Amazon.SimpleEmail;
using Amazon.SimpleEmail.Model;
using System.IO;
namespace SendEmail
{
class Program
{
static void Main(string[] args)
{
//Remember to enter your (AWSAccessKeyID, AWSSecretAccessKey) if not using and IAM User with credentials assigned to your instance and your RegionEndpoint
using (var client = new AmazonSimpleEmailServiceClient("YourAWSAccessKeyID", "YourAWSSecretAccessKey", RegionEndpoint.USEast1))
{
var emailRequest = new SendEmailRequest()
{
Source = "FROMADDRESS#TEST.COM",
Destination = new Destination(),
Message = new Message()
};
emailRequest.Destination.ToAddresses.Add("TOADDRESS#TEST.COM");
emailRequest.Message.Subject = new Content("Hello World");
emailRequest.Message.Body = new Body(new Content("Hello World"));
client.SendEmail(emailRequest);
}
}
}
}
