Program:

The source code to create a thread in C# is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

/*
 * Program to create a thread in C#
 */
using System;
using System.Threading;

class ThreadEx
{
    public void MyThreadFun()
    {
        int i = 0;
        for (i = 1; i<=4; i++)
        {
            Console.WriteLine("Thread Executed");
        }
    }
}
class Program
{
    public static void Main()
    {
        ThreadEx T = new ThreadEx();
        Thread t1 = new Thread(new ThreadStart(T.MyThreadFun));
        t1.Start();
    }
}

Output:

Thread Executed
Thread Executed
Thread Executed
Thread Executed

Explanation:

In the above program, we imported System.Threading namespace to create a thread. Here we created a class ThreadEx that a method MyThreadFun() to implement thread. We also created a Program class that contains the Main() method.

In the Main() method we created object T of class ThreadEx.

Thread t1 = new Thread(new ThreadStart(T.MyThreadFun));

In the above statement we passed the method to delegate ThreadStart and then pass delegate ThreadStart as a parameter in the constructor of Thread class, and then finally called Start() method to execute the thread.
