Crystal report method not found - asp.net

Question

I made a feedback project. I made it on ASP.NET MVC 5 it also has crystal reports. reports were working fine, but suddenly they stopped to work. I don't what happened with them. but since last week I tried hard to find solution but unfortunately could not get the right one who solved the solution. I downloaded different run times but all went vain. this is the bottom line of error.
"Method not found: 'CrystalDecisions.ReportAppServer.DataDefModel.PropertyBag CrystalDecisions.ReportAppServer.ReportDefModel.ISCRExportOptions.get_ExportOptionsEx()'"
this is the code:
public CrystalReportFeedback UserFeedbackDateWise(FeedbackReport be){
if (Session["CurrentUser"] != null && Convert.ToInt32(Session["User_Id"]) != 0)
{
string reportPath = Path.Combine(Server.MapPath("~/Reports"), "UserFeedbackReport.rpt");
if (ModelState.IsValid)
{
be.FromDate = Convert.ToDateTime(TempData["UserFromDate"]);
be.ToDate = Convert.ToDateTime(TempData["UserToDate"]);
be.User_Id = Convert.ToInt32(Session["User_Id"]);
}
return new CrystalReportFeedback(reportPath, be);
}
else
{
return null;
//new CrystalReportFeedback(reportPath, be);
}
}
Init of the report :
public CrystalReportFeedback(string reportPath, FeedbackReport be)//, object dataSet)
{
//int[] array;
string strConnect = Convert.ToString(System.Configuration.ConfigurationManager.ConnectionStrings["TSC"]);
SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(strConnect);
string _username = builder.UserID;
string _pass = builder.Password;
string _server = builder.DataSource;
string _database = builder.InitialCatalog;
ReportDocument reportDocument = new ReportDocument();
//
reportDocument.Load(reportPath);
reportDocument.SetDatabaseLogon(_username, _pass, _server, _database);
if (be.Region_Id != 0)
{
reportDocument.SetParameterValue("#Region_Id", be.Region_Id);
}
if (be.User_Id != 0)
{
reportDocument.SetParameterValue("#User_Id", be.User_Id);
}
reportDocument.SetParameterValue("#FromDate", be.FromDate);
reportDocument.SetParameterValue("#ToDate", be.ToDate);
//reportDocument.ExportToDisk(ExportFormatType.PortableDocFormat, "C:\report.pdf");
_contentBytes = StreamToBytes(reportDocument.ExportToStream(ExportFormatType.PortableDocFormat));
}
Export method :
public override void ExecuteResult(ControllerContext context)
{
var response = context.HttpContext.ApplicationInstance.Response;
response.Clear();
response.Buffer = false;
response.ClearContent();
response.ClearHeaders();
response.Cache.SetCacheability(HttpCacheability.Public);
response.ContentType = "application/pdf";
using (var stream = new MemoryStream(_contentBytes))
{
stream.WriteTo(response.OutputStream);
stream.Flush();
}
}
private static byte[] StreamToBytes(Stream input)
{
byte[] buffer = new byte[16 * 1024];
using (MemoryStream ms = new MemoryStream())
{
int read;
while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
{
ms.Write(buffer, 0, read);
}
return ms.ToArray();
}
}
Hope that I will get my solution at earliest.
this is modified code:
[HttpGet]
public FileResult UserFeedbackDateWise(FeedbackReport be)
{
if (Session["CurrentUser"] != null && Convert.ToInt32(Session["User_Id"]) != 0)
{
string reportPath = Path.Combine(Server.MapPath("~/Reports"), "UserFeedbackReport.rpt");
if (ModelState.IsValid)
{
be.FromDate = Convert.ToDateTime(TempData["UserFromDate"]);
be.ToDate = Convert.ToDateTime(TempData["UserToDate"]);
be.User_Id = Convert.ToInt32(Session["User_Id"]);
}
string strConnect = Convert.ToString(System.Configuration.ConfigurationManager.ConnectionStrings["TSC"]);
SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(strConnect);
string _username = builder.UserID;
string _pass = builder.Password;
string _server = builder.DataSource;
string _database = builder.InitialCatalog;
ReportDocument reportDocument = new ReportDocument();
//
reportDocument.Load(reportPath);
reportDocument.SetDatabaseLogon(_username, _pass, _server, _database);
if (be.Region_Id != 0)
{
reportDocument.SetParameterValue("#Region_Id", be.Region_Id);
}
if (be.User_Id != 0)
{
reportDocument.SetParameterValue("#User_Id", be.User_Id);
}
reportDocument.SetParameterValue("#FromDate", be.FromDate);
reportDocument.SetParameterValue("#ToDate", be.ToDate);
Stream stream = reportDocument.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
//Here i have my stream with my pdf report, i just create a new FileStreamResult and return it to my client like that :
FileStreamResult myfile = new FileStreamResult(stream, "application/pdf");
return myfile;
//new CrystalReportFeedback(reportPath, be);
}
else
{
return null;
//new CrystalReportFeedback(reportPath, be);
}
}

Answer 1

This isn't a coding issue, it's a runtime issue. The version of the crystal runtime or the bitness of your application.
One thing to try first is to upgrade both your development version and ensure you're running the same version in production. See https://apps.support.sap.com/sap/support/knowledge/public/en/2148492 for more details
It says:
Compile your application either to 'X86 mode' or 'X64 mode'
Install the particular versions of runtimes on deployment machine.
i.e. If the application is compiled as 32 bit, then install the 32bit runtimes.

I'll try my best to help you exporting your report, but your post is not very clear. For your next post try to be very specific and provide as much information as you can.
I currently made a MVC project and export a crystalreport report from my controller to my client.
I think that your ExecuteResult method can work, but working with the httpcontext is useless, Crystalreport and .NET provide some useful methods to do the same.
So i'll show you how i create and export my report so you can copy / paste and modify your code.
Here is my controller method, called from a button :
[HttpGet]
public FileResult InitReport()
{
//I create my report here
FileImportReport rptH = new FileImportReport();
// Some configuration on the report, datasource, databaselogon .. etc
...
//
//Then I export my report to a pdf stream like that :
Stream stream = rptH.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
//Here i have my stream with my pdf report, i just create a new FileStreamResult and return it to my client like that :
FileStreamResult myfile = new FileStreamResult(stream, "application/pdf");
return myfile;
}
My method is called from a button but it can work like you want, or the file can be saved in any known path.
You can test to reproduce my code, in your CrystalReportFeedback method use my code with your reportDocument object, you don't need to use your StreamToBytes method.
