CredentialCache.Remove Method (Uri, String)
Assembly: System (in system.dll)
A Uri that specifies the URI prefix of the resources that the credential is used for.
The authentication scheme used by the host named in uriPrefix.
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 a null reference (Nothing in Visual Basic) or uriPrefix is a null reference (Nothing in Visual Basic), or no matching credential is found in the cache, this method does nothing.
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.set_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.get_RequestUri(), "Basic"); Console.WriteLine("\nYour credentials have now been removed " + "from the program's CredentialCache"); myWebResponse.Close();
