getting Internal Server Error when call a Web API by async

Rupesh Kahane

I have created an Web API application.

This application I have hosted on one server.

Now I am calling a post method of that (hosted ) application using async call in another application, so If I put a debugger then I am getting an Internal Server Error when call a Web API by async.

Bellow is my code

public async void PostRequest(string name)

{

try

{

string name = "rupesh";

Uri requestUri = new Uri("http://xxxxx:2565/api/Registration/SignUp"); //replace your Url

string json = "";

json = Newtonsoft.Json.JsonConvert.SerializeObject(name);

var objClint = new System.Net.Http.HttpClient();

System.Net.Http.HttpResponseMessage respon = await objClint.PostAsync(requestUri, new StringContent(json, System.Text.Encoding.UTF8, "application/json"));

string responJsonText = await respon.Content.ReadAsStringAsync();

}

catch (Exception ex)

{

var er = ex.Message.ToString();

}

Give me some solution.

Thanks

I am new in Xamarin Development.
Very Important => if you are using any Web Service for your App then do not forget to give permissions to access Internet.
Steps:
1. Right-click on your android project and select Properties.
2. Select Android Manifest in the window that opens.
3. Check the permission that you want to require in the list of permissions i.e check the checkbox of "Internet"

Hi,
I think you are posting huge amount of data and you application not able to manage that type of thread,so just use Await Async.

Hi.
May be the internal server error arises due to CORS or may be the error arises due to Uri which is used may not be accessible. So could please check at your end.
thanks.
