CredentialCache.Remove Method (Uri, String)

Deletes a NetworkCredential instance from the cache if it is associated with the specified Uniform Resource Identifier (URI) prefix and authentication protocol.

Namespace:  System.Net
Assembly:  System (in System.dll)

public void Remove(
	Uri uriPrefix,
	string authType


Type: System.Uri
A Uri that specifies the URI prefix of the resources that the credential is used for.
Type: System.String
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 null or uriPrefix is null, 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.
Console.WriteLine("\nYour credentials have now been removed from the program's CredentialCache");
