I have a query that how can i post data using web Api in winforms application. Currently it giving me error which is below . I check web api using Postman App. It's working fine.But when i post data using winforms it returning me status code 200 and data is not inserting in database.Any help will be appreciated.

What I have tried:

winforms button click event

       private void button1_Click(object sender, EventArgs e)
        {
        try
        {
            EmployeeClass emp = new EmployeeClass() { Project_Name = "Hello",
             Task = "Task", Username 
              = "fazal" };
            HttpClient client = new HttpClient();
            client.BaseAddress = new Uri("https://localhost:44342/");
            HttpResponseMessage responseMessage = 
            client.PostAsJsonAsync("api/values/AddTask", 
           emp).Result;
            }
            catch (Exception ex)
             {

            MessageBox.Show(ex.Message);
            }
       
        }

Here is return

{StatusCode: 200, ReasonPhrase: 'OK', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:{ Pragma: no-cache X-SourceFiles: =?UTF-8?B?

The Web Api controller Code is

    database_access_layer.db dblayer = new database_access_layer.db();

    [HttpPost]

    public IHttpActionResult AddTask([FromBody] Taskcs css)
    { 
        try
        {
          dblayer.AddTask(css);
            return Ok("Success");
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex);
            return Ok("Something not OK ");
        }

    }

Status code 200 means the request succeeded. But that's expected, since you always return Ok, even if an error occurs.

Change your API method to return a more appropriate response when an exception is thrown. For example:

C#

[HttpPost]
public IHttpActionResult AddTask([FromBody] Taskcs task)
{ 
    try
    {
        dblayer.AddTask(task);
        return Ok();
    }
    catch (Exception ex)
    {
        return InternalServerError(ex);
    }
}

NB: If there are specific exceptions which you know your AddTask might throw, you might want to handle them differently. For example:

C#

catch (DuplicateKeyException ex)
{
    return Conflict();
}
catch (ValidationFailedException ex)
{
    return BadRequest(ex.Message);
}
catch (Exception ex)
{
    return InternalServerError(ex);
}

NB 2: Your client code is currently blocking the UI waiting for the request to complete. You should avoid using this sort of sync-over-async approach, since it could lead to your application hanging.

C#

private void button1_Click(object sender, EventArgs e)
{
    _ = AddEmployeeAsync();
}

private async Task AddEmployeeAsync()
{
    try
    {
        EmployeeClass emp = new EmployeeClass
        {
            Project_Name = "Hello",
            Task = "Task", 
            Username = "fazal" 
        };
        
        HttpClient client = new HttpClient();
        client.BaseAddress = new Uri("https://localhost:44342/");
        
        using (HttpResponseMessage response = await client.PostAsJsonAsync("api/values/AddTask", emp))
        {
            response.EnsureSuccessStatusCode();
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}
