{
   Console::WriteLine( L"IsAuthenticated: {0}", stream->IsAuthenticated );
   Console::WriteLine( L"IsMutuallyAuthenticated: {0}", stream->IsMutuallyAuthenticated );
   Console::WriteLine( L"IsEncrypted: {0}", stream->IsEncrypted );
   Console::WriteLine( L"IsSigned: {0}", stream->IsSigned );
   Console::WriteLine( L"ImpersonationLevel: {0}", stream->ImpersonationLevel );
   Console::WriteLine( L"IsServer: {0}", stream->IsServer );
}

 static void DisplayAuthenticationProperties(NegotiateStream stream)
{
     Console.WriteLine("IsAuthenticated: {0}", stream.IsAuthenticated);
    Console.WriteLine("IsMutuallyAuthenticated: {0}", stream.IsMutuallyAuthenticated);
    Console.WriteLine("IsEncrypted: {0}", stream.IsEncrypted);
    Console.WriteLine("IsSigned: {0}", stream.IsSigned);
    Console.WriteLine("ImpersonationLevel: {0}", stream.ImpersonationLevel);
    Console.WriteLine("IsServer: {0}", stream.IsServer);
}

Remarks

You must successfully authenticate before calling this method. Clients specify the impersonation level when they request authentication by calling one of the AuthenticateAsClient or BeginAuthenticateAsClient methods. If you authenticate without specifying a TokenImpersonationLevel , Identification is used.
