Sort calculator in C#

This is a windows form sort calculator in c#  that allows a user to input a number of arrays elements he wants and the program will generate random numbers of the inputted value.

Then the user has the opportunity the to choose which sort he wants to use.

I implemented several sorts including select sort, bubble sort, quick sort, merge sort and heap sort.

Most of the code is self-explanatory. I am still a novice in windows forms and c# in general and I would be glad if someone would be in a position to recommend a better approach in design but generally the program works fine.
