WebResponse.Close Method

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

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

Exceptions

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

Remarks

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

Note   The response must be closed to avoid running out of system resources. The response stream can be closed by calling Stream.Close or Close.
Note   The WebResponse class is an abstract (MustInherit in Visual Basic) 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.

Example

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

[Visual Basic] 
' 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
myWebResponse.Close()
Console.WriteLine(ControlChars.Cr + "Response Stream successfully closed")

[C#] 
// 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.
myWebResponse.Close();
Console.WriteLine("\nResponse Stream successfully closed");

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

// Process the response here.
Console::WriteLine(S"\nResponse Received::Trying to Close the response stream..");
// Release resources of response Object*.
myWebResponse->Close();
Console::WriteLine(S"\nResponse Stream successfully closed");
