Continuing with the last post on authentication issues with wsdl.exe-generated SOAP<\/a> proxies, you may need to handle HTTP status codes to provide custom exceptions.  To do this, the SoapHttpClientProtocol<\/a> class (actually its parent HttpWebClientProtocol<\/a>) provides a pair of GetWebResponse()<\/a> methods for derived classes to override.  One method is for synchronous calls and the other for asynchronous.<\/p>\n

The following code shows how to generate a custom exception for the HTTP 401 Unauthorized code.<\/p>\n

using System;
using System.Net;
 
public class MyProxy : WsdlExeGeneratedProxy
{
   protected override WebRequest GetWebRequest(Uri uri)
   {
      HttpWebRequest request = base.GetWebRequest(uri) as HttpWebRequest;
      request.Headers.Add(\"accept-language\", CultureInfo.CurrentUICulture.Name);
      request.Credentials = m_state.Credentials;
      return request;
   }
   protected override WebResponse GetWebResponse(WebRequest request)
   {
      HttpWebResponse response = base.GetWebResponse(request) as HttpWebResponse;
      ThrowIfUnauthorized(response);
      return response;
   }
   protected override WebResponse GetWebResponse(WebRequest request, IAsyncResult result)
   {
      HttpWebResponse response = base.GetWebResponse(request, result) as HttpWebResponse;
      ThrowIfUnauthorized(response);
      return response;
   }
   private void ThrowIfUnauthorized(HttpWebResponse response)
   {
      \/\/ There are cases where response can be null (dropped network connection is one).
      if (response != null && response.StatusCode == HttpStatusCode.Unauthorized)
      {
         throw new UnauthorizedException(response);
