How to create a thread in C#?

Threads are lightweight processes. A thread is defined as the execution path of a program. Threads are created by extending the Thread class. The extended Thread class then calls the Start() method to begin the child thread execution.

Example of Thread: One common example of use of thread is implementation of concurrent programming by modern operating systems. Use of threads saves wastage of CPU cycle and increase efficiency of an application.

The following is an example showing how to create a thread.

Example

 Live Demo

using System;
using System.Threading;
namespace Demo {
   class Program {
      public static void ThreadFunc() {
         Console.WriteLine("Child thread starts");
      }
      static void Main(string[] args) {
         ThreadStart childref = new ThreadStart(ThreadFunc);
         Console.WriteLine("In Main: Creating the Child thread");
         Thread childThread = new Thread(childref);
         childThread.Start();
         Console.ReadKey();
      }
   }
}

Output

In Main: Creating the Child thread
Child thread starts
