In this program i have used the simple login system, and it will be easy to understand by every one even he is a beginner or new for the C# programming.
In this program if the condition matches than the program give false output result.
as we can see i have putted the username - admin and password - admin123, if we insert this pair of username and password than it will give the false output because it is NOT Operator.
ENJOY CODING!!!
