Threading: 01- A Simple Thread

Program in the Sample 00 can be converted to utilize the thread as follows.


using System;
using System.Threading;

class Program {
    static void Main(string[] args) {
        Console.WriteLine("Main Started");
        var th = new Thread(Greet); // Create new thread
        th.Start();  // Execute Greet method in the created thread
        Console.WriteLine("Main Completed");

    private static void Greet() {
        Console.WriteLine("Hi, Good Morning!");


  • Constructor of Thread class here, received the method to be invoked using a delegate called ThreadStart which is defined in BCL.
  • Console application by default run in Main thread.
  • During th.Start, runtime creates a new thread and starts the execution of Greet method in that thread.
  • So the line after th.Start will continue to execute while Greet method is being executed in a new thread.
  • Result will vary based on system performance.


Main Started
Main Completed

Hi, Good Morning!
