使用例

[Visual Basic, C#, C++] StatusCode を使用して HttpWebResponse のステータスが OK であることを確認する例を次に示します。

 
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 occured : {0}", e.Status)
    Catch e As Exception
        Console.WriteLine(ControlChars.NewLine + "The following exception was raised : {0}", e.Message)
    End Try
End Sub 

[C#] 
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 occured : {0}",e.Status); 
       }
    catch(Exception e)
    {
        Console.WriteLine("\nThe following Exception was raised : {0}",e.Message);
    }
}

[C++] 
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(S"\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(S"\r\nWebException Raised. The following error occured : {0}",
         __box(e->Status));
   } catch (Exception* e) {
      Console::WriteLine(S"\nThe following Exception was raised : {0}",
         e->Message);
   }
