If you are a c# beginner or want to start learning the c# programming language, then this program will help you to understand the basics of c# programming. In this program, we are going to share C# program to describe the C# program to perform merge sort.
To increase your C# knowledge, practice all C sharp programs:
Copy the below c# program and execute it in your Microsoft Visual Studio IDE (Integrated Development Environment ). At the end of this program, I have shared the output program.
