Examples

The following code example uses this method to delete a NetworkCredential instance from the cache.

// Create a webrequest with the specified url.
WebRequest^ myWebRequest = WebRequest::Create( url );
myWebRequest->Credentials = myCredentialCache;
Console::WriteLine( "\nLinked CredentialCache to your request." );
// Send the request and wait for response.
WebResponse^ myWebResponse = myWebRequest->GetResponse();

// Process response here.

Console::Write( "Response received successfully." );

// Call 'Remove' method to dispose credentials for current Uri as not required further.
myCredentialCache->Remove( myWebRequest->RequestUri, "Basic" );
Console::WriteLine( "\nYour credentials have now been removed from the program's CredentialCache" );
myWebResponse->Close();
// Create a webrequest with the specified url.
WebRequest myWebRequest = WebRequest.Create(url);
myWebRequest.Credentials = myCredentialCache;
Console.WriteLine("\nLinked CredentialCache to your request.");
// Send the request and wait for response.
WebResponse myWebResponse = myWebRequest.GetResponse();

// Process response here.

Console.Write("Response received successfully.");
// Call 'Remove' method to dispose credentials for current Uri as not required further.
myCredentialCache.Remove(myWebRequest.RequestUri,"Basic");
Console.WriteLine("\nYour credentials have now been removed from the program's CredentialCache");
myWebResponse.Close();
' Create a webrequest with the specified url .
Dim myWebRequest As WebRequest = WebRequest.Create(url)
myWebRequest.Credentials = myCredentialCache
Console.WriteLine(ControlChars.Cr + "Linked CredentialCache to your request.")
' Send the request and wait for response.
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()

'Process the response here

Console.Write("Response received successfully.")
'Call 'Remove' method to dispose credentials for current Uri as they would not be; 
'required in any of the future requests.
myCredentialCache.Remove(myWebRequest.RequestUri, "Basic")
Console.WriteLine(ControlChars.Cr + "Your credentials have now been removed from the program's CredentialCache")
myWebResponse.Close()

Remarks

This method removes a NetworkCredential instance from the CredentialCache if the specified URI prefix and authentication protocol match those associated with the credential. Multiple calls to the Remove method for the same NetworkCredential have no effect.

If authType is null or uriPrefix is null, or no matching credential is found in the cache, this method does nothing.
