CredentialCache.Remove Method (String, Int32, String)
Deletes a NetworkCredential instance from the cache if it is associated with the specified host, port, and authentication protocol.
Assemblies: System (in System.dll)
System.Net.Primitives (in System.Net.Primitives.dll)
This method removes a NetworkCredential instance from the CredentialCache if the specified host, port, 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.
