Read API Json Data - asp.net

Question

I want to create a windows console application to read Json api data, retrieve all the type="folder" items and then save the data to database. How to access to the properties of the Json data?
Json data format:
{
asset:{
path:{
Children:[
0:{
id:xxxx,
type: folder
},
1:{
id:xxxxx,
type: folder
},
2:{
id:xxxx,
type: page
}
...
]
}
},
success:ok
}
FolderModel:
public class FolderModel
{
public string id { get; set; }
public string type { get; set; }
}
//main
static void Main(string[] args)
{
Task T = new Task(ApiCall);
T.Start();
Console.ReadLine();
}
//apicall
static async void ApiCall()
{
using (var client = new HttpClient())
{
HttpResponseMessage response = await client.GetAsync("https://apiurl/");
response.EnsureSuccessStatusCode();
using (HttpContent content = response.Content)
{
string responseBody = await response.Content.ReadAsStringAsync();
var items = JsonConvert.DeserializeObject<FolderModel>(responseBody);
//items id and type are null here. how to retrieve those information ??
}
}
}

Answer 1

Your JSON and c# model are not identical first you need to create models to deserialize json
public class FolderModel
{
public string id { get; set; }
public string type { get; set; }
}
public class Path
{
public List<FolderModel> Children { get; set; }
}
public class Asset
{
public Path path { get; set; }
}
public class ResponseModel
{
public Asset asset { get; set; }
public string Success { get; set; }
}
Now you can access deserialize using
var response = JsonConvert.DeserializeObject<ResponseModel>(responseBody);
Now you can acess properties using linq or foreach loop
Using Linq
var folderResponse = response.asset.path.Children.Select(x => new
FolderModel { id = x.id, type = x.type });
//or you can access like this if you need to get all fields
var folderResponse = response.asset.path.Children.Select(x => x);
ForEach
foreach (var folder in response.asset.path.Children)
{
//folder.id
//folder.type
}
JSON to parse
{
"asset": {
"path": {
"Children": [
{
"id": "xxxx",
"type": "folder"
},
{
"id": "xxxxx",
"type": "folder"
},
{
"id": "xxxx",
"type": "page"
}
]
}
},
"success": "ok"
}
