WebResponse.Close Method


When overridden by a descendant class, closes the response stream.

 virtual void Close();
public virtual void Close ();
abstract member Close : unit -> unit
override this.Close : unit -> unit
Public Overridable Sub Close ()


Any attempt is made to access the method, when the method is not overridden in a descendant class.


The following example uses the Close method to close the WebResponse.

// Create a 'WebRequest' object with the specified url.
WebRequest^ myWebRequest = WebRequest::Create( "http://www.contoso.com" );
// Send the 'WebRequest' and wait for response.
WebResponse^ myWebResponse = myWebRequest->GetResponse();

// Process the response here.
Console::WriteLine( "\nResponse Received::Trying to Close the response stream.." );
// Release resources of response Object*.
Console::WriteLine( "\nResponse Stream successfully closed" );
// Create a 'WebRequest' object with the specified url. 	
WebRequest myWebRequest = WebRequest.Create("http://www.contoso.com"); 
// Send the 'WebRequest' and wait for response.	
WebResponse myWebResponse = myWebRequest.GetResponse(); 

// Process the response here.
Console.WriteLine("\nResponse Received.Trying to Close the response stream..");
// Release resources of response object.
Console.WriteLine("\nResponse Stream successfully closed");
' Create a 'WebRequest' object with the specified url 	
Dim myWebRequest As WebRequest = WebRequest.Create("www.contoso.com")
' Send the 'WebRequest' and wait for response.	
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()

'  Process the response here
Console.WriteLine(ControlChars.Cr + "Response Received.Trying to Close the response stream..")
' Release resources of response object
Console.WriteLine(ControlChars.Cr + "Response Stream successfully closed")


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


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


The WebResponse class is an abstract class. The actual behavior of WebResponse instances at run time is determined by the descendant class returned by WebRequest.GetResponse. For more information about default values and exceptions, please see the documentation for the descendant classes, such as HttpWebResponse and FileWebResponse.
