InvalidCredentialException Class

Note: This class is new in the .NET Framework version 2.0.

The exception that is thrown when authentication fails for an authentication stream and cannot be retried.

Namespace: System.Security.Authentication
Assembly: System (in system.dll)

[SerializableAttribute] 
public ref class InvalidCredentialException : public AuthenticationException
/** @attribute SerializableAttribute() */ 
public class InvalidCredentialException extends AuthenticationException
SerializableAttribute 
public class InvalidCredentialException extends AuthenticationException

The NegotiateStream and SslStream classes throw this exception when authentication fails. This exception indicates that the underlying stream is not in a valid state and you cannot retry the authentication using the NegotiateStream or SslStream instance. If you can retry the authentication, an AuthenticationException is thrown instead of the InvalidCredentialException.
