Factorial Solver in C#

To all my visitors and followers of my website thank you for visiting even though I'm not earning any money here but still I want to spread the message to share the knowledge in computer programming to all. Anyway in this article I would like to share with you a sample program that I used using C# to accept a number from our user and then our program will compute the factorial equivalent of the given number by our user. The code is very short and easy to understand.
