示例

下面的示例使用 StatusDescription 验证 HttpWebResponse 的状态是否为 "正常"。The following example uses StatusDescription to verify that the status of the HttpWebResponse is OK.

void GetPage( String^ url )
{
   try
   {
      // Creates an HttpWebRequest for the specified URL.
      HttpWebRequest^ myHttpWebRequest = dynamic_cast<HttpWebRequest^>(WebRequest::Create( url ));
      // Sends the HttpWebRequest and waits for a response.
      HttpWebResponse^ myHttpWebResponse = dynamic_cast<HttpWebResponse^>(myHttpWebRequest->GetResponse());
      if ( myHttpWebResponse->StatusCode == HttpStatusCode::OK )
      {
         Console::WriteLine( "\r\nResponse Status Code is OK and StatusDescription is: {0}",
            myHttpWebResponse->StatusDescription );
      }
      // Releases the resources of the response.
      myHttpWebResponse->Close();
   }
   catch ( WebException^ e ) 
   {
      Console::WriteLine( "\r\nWebException Raised. The following error occurred : {0}", e->Status );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "\nThe following Exception was raised : {0}", e->Message );
   }
}
public static void GetPage(String url) 
{
    try 
      {	
            // Creates an HttpWebRequest for the specified URL. 
            HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url); 
            // Sends the HttpWebRequest and waits for a response.
            HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse(); 
            if (myHttpWebResponse.StatusCode == HttpStatusCode.OK)
               Console.WriteLine("\r\nResponse Status Code is OK and StatusDescription is: {0}",
                                    myHttpWebResponse.StatusDescription);
            // Releases the resources of the response.
            myHttpWebResponse.Close(); 
        
        } 
    catch(WebException e) 
       {
            Console.WriteLine("\r\nWebException Raised. The following error occurred : {0}",e.Status); 
       }
    catch(Exception e)
    {
        Console.WriteLine("\nThe following Exception was raised : {0}",e.Message);
    }
}
Public Shared Sub GetPage(url As [String])
   Try
        ' Creates an HttpWebRequest with the specified URL.
        Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create(url), HttpWebRequest)
        ' Sends the request and waits for a response.
        Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
        If myHttpWebResponse.StatusCode = HttpStatusCode.OK Then
            Console.WriteLine(ControlChars.Lf + ControlChars.NewLine + "Response Status Code is OK and StatusDescription is: {0}", myHttpWebResponse.StatusDescription)
        End If
        ' Release the resources of the response.
        myHttpWebResponse.Close()
    
    Catch e As WebException
        Console.WriteLine(ControlChars.Lf + ControlChars.NewLine + "Exception Raised. The following error occurred : {0}", e.Status)
    Catch e As Exception
        Console.WriteLine(ControlChars.NewLine + "The following exception was raised : {0}", e.Message)
    End Try
End Sub
