WebException.Response Property

Definition

Namespace:

System.Net

Assemblies:

netstandard.dll, System.Net.Requests.dll

Source:

WebException.cs

Gets the response that the remote host returned.

C#

public System.Net.WebResponse? Response { get; }

Property Value

WebResponse

If a response is available from the Internet resource, a WebResponse instance that contains the error response from an Internet resource; otherwise, null.

Examples

The following example checks the Status property and prints to the console the StatusCode and StatusDescription of the underlying HttpWebResponse instance.

C#

try {
   // Create a web request for an invalid site. Substitute the "invalid site" strong in the Create call with a invalid name.
     HttpWebRequest myHttpWebRequest = (HttpWebRequest) WebRequest.Create("invalid site");

    // Get the associated response for the above request.
     HttpWebResponse myHttpWebResponse = (HttpWebResponse) myHttpWebRequest.GetResponse();
    myHttpWebResponse.Close();
}
catch(WebException e) {
    Console.WriteLine("This program is expected to throw WebException on successful run."+
                        "\n\nException Message :" + e.Message);
    if(e.Status == WebExceptionStatus.ProtocolError) {
        Console.WriteLine("Status Code : {0}", ((HttpWebResponse)e.Response).StatusCode);
        Console.WriteLine("Status Description : {0}", ((HttpWebResponse)e.Response).StatusDescription);
    }
}
catch(Exception e) {
    Console.WriteLine(e.Message);
}

Remarks

Some Internet protocols, such as HTTP, return otherwise valid responses indicating that an error has occurred at the protocol level. When the response to an Internet request indicates an error, WebRequest.GetResponse sets the Status property to WebExceptionStatus.ProtocolError and provides the WebResponse that contains the error message in the Response property of the WebException that was thrown. The application can examine the WebResponse to determine the actual error.
