In C#, the MachineName property of the Environment class is used to find the name of the computer on which the program is running.

Below is a sample code for usage.

namespace ConsoleApplicationTest
{
    class Program {

        static void Main(string[] args) {

            string cName = System.Environment.MachineName;

            Console.WriteLine(cName);
            Console.ReadLine();

        }
    }
}
