FileWebResponse.Close Method

Closes the response stream.

[Visual Basic]
Overrides Public Sub Close()
[C#]
public override void Close();
[C++]
public: void Close();
[JScript]
public override function Close();

Remarks

The Close method cleans up the resources used by a FileWebResponse and closes the response stream by calling the Stream.Close method.

Note   The response stream must be closed to avoid running out of system resources. You can closes the response stream by calling either Stream.Close or Close

Example

[Visual Basic, C#, C++] The following example uses the Close method to close the response stream.

[Visual Basic] 
Public Shared Sub GetPage(url As [String])
    Try
        Dim fileUrl As New Uri("file://" + url)
        ' Create a FileWebrequest with the specified Uri. 
        Dim myFileWebRequest As FileWebRequest = CType(WebRequest.Create(fileUrl), FileWebRequest)
        ' Send the 'fileWebRequest' and wait for response.
        Dim myFileWebResponse As FileWebResponse = CType(myFileWebRequest.GetResponse(), FileWebResponse)
        ' Process the response here                        
        Console.WriteLine(ControlChars.Cr + "Response Received.Trying to Close the response stream..")
        ' The method call to release resources of response object.
        myFileWebResponse.Close()
        Console.WriteLine(ControlChars.Cr + "Response Stream successfully closed")
    Catch e As WebException
        Console.WriteLine(ControlChars.Lf + ControlChars.Cr + "The Reason for failure is : {0}", e.Status)
    Catch e As Exception
        Console.WriteLine(ControlChars.Cr + "The following exception was raised : {0}", e.Message)
    End Try

[C#] 
public static void GetPage(String url) 
 {
     try 
     {     
         Uri fileUrl = new Uri("file://"+url);
         // Create a FileWebrequest with the specified Uri. 
         FileWebRequest myFileWebRequest = (FileWebRequest)WebRequest.Create(fileUrl); 
         // Send the 'fileWebRequest' and wait for response.
         FileWebResponse myFileWebResponse = (FileWebResponse)myFileWebRequest.GetResponse(); 
         // Process the response here.
         Console.WriteLine("\nResponse Received.Trying to Close the response stream..");
         // Release resources of response object.
         myFileWebResponse.Close();
      Console.WriteLine("\nResponse Stream successfully closed.");            
      } 
     catch(WebException e) 
      {
        Console.WriteLine("\r\nWebException thrown.The Reason for failure is : {0}",e.Status); 
    }
     catch(Exception e)
    {
        Console.WriteLine("\nThe following Exception was raised : {0}",e.Message);
     }
}

[C++] 
void GetPage(String* url) {
   try {
      Uri* fileUrl = new Uri(String::Concat(S"file://", url));
      // Create a FileWebrequest with the specified Uri.
      FileWebRequest* myFileWebRequest = dynamic_cast<FileWebRequest*>(WebRequest::Create(fileUrl));
      // Send the 'fileWebRequest' and wait for response.
      FileWebResponse* myFileWebResponse = dynamic_cast<FileWebResponse*>(myFileWebRequest->GetResponse());
      // Process the response here.
      Console::WriteLine(S"\nResponse Received::Trying to Close the response stream..");
      // Release resources of response Object*.
      myFileWebResponse->Close();
      Console::WriteLine(S"\nResponse Stream successfully closed.");
   } catch (WebException* e) {
      Console::WriteLine(S"\r\nWebException thrown.The Reason for failure is : {0}", __box( e->Status));
   } catch (Exception* e) {
      Console::WriteLine(S"\nThe following Exception was raised : {0}", e->Message);
   }
}
