Difference between the largest and smallest value in C#

 A simple program to ask the user to give a series of numbers and then the program will compute the difference between the largest and smallest number in C# programming language.

I am currently accepting programming work, IT projects, school and application development, programming projects, thesis and capstone projects, IT consulting work, computer tutorials, and web development work kindly contact me at the following email address for further details.  If you want to advertise on my website kindly contact me also in my email address also. Thank you.
