Get status code with HttpClient

I am using the following code to get a string from a server:

Code:

---

Dim handler = New HttpClientHandler With {.UseCookies = False}
Dim http As New HttpClient(handler)
Dim url1 As String = "SomeUrlString"

http.DefaultRequestHeaders.Clear()
http.DefaultRequestHeaders.Add("User-Agent", useragent)
http.DefaultRequestHeaders.Add("Cookie", "mac=" & myMac)

Try

    result = http.GetStringAsync(url1).Result

Catch ex As Exception
    Console.WriteLine(ex.ToString)
End Try

---

I would like to be able to get the status code that is returned by the server. ie. 200, 404, etc., but I can't figure out how to do it.
Can anyone help me out? Thanks...

Don't just catch Exception instead catch https://learn.microsoft.com/en-us/do...n?view=net-8.0 as this will give you the status code if an error occurs. If there was no error then it is probably safe to assume the status code was 200.

PD ... I did try HttpRequestException, but it never gets thrown. The only ones that get thrown are generic Exception, as in my code above, or AggregateException. BTW, the code above is running in a thread, if that makes any difference.

Typically AggregateException is thrown by code executing as part of the Task Parallel Library or PLinq, if you are getting an AggregateException then you probably want to investigate the exception's InnerException property to get access to the real exceptions.

I would be surprised if HttpClient is throwing a generic Exception though - it should only throw exception's derived from Exception.

If change the expected string to HttpResponseMessage , so getAsync then you can use.
response.EnsureSuccessStatusCode();
After the getasync

Can you give me a quick example?

I forgot and was writing in C# but:

Code:

---

  using (HttpClient client = new HttpClient())
            {
                HttpResponseMessage response = await client.SendAsync(request1);
               
                try
                {
                    response.EnsureSuccessStatusCode();
                }
              catch (Exception ex)
                {

                    //ex.Message
            //      return;
              }
             
                responseBody1 = await response.Content.ReadAsStringAsync();
            }
