C#/.NET - create thread

8 points
Created by:

In this short article, we want to show you how to create and run a new thread in C# / .NET.

Note: there are different ways how to create threads but in this article we use simple approach based on Thread class.

Quick solution:

// using System.Threading;

Thread thread = new Thread(() =>
    // put some source code here ...



Practical example

In this section new Thread object is created for logic passed in the constructor argument. Created thread is not run until Start() method is called. Thread is running until indicated logic does not end execution.

Source code:

using System;
using System.Threading;

public class Program
	public static void Main(string[] args)
		Thread thread = new Thread(() =>
			for (int i = 1; i <= 5; ++i)
				Console.WriteLine("Iteration: " + i);
				Thread.Sleep(1000); // sleeps created thread for 1 second


Output (Linux Mono):

Iteration: 1
Iteration: 2
Iteration: 3
Iteration: 4
Iteration: 5

Hint: to stop thread Thread Abort() method can be used too but it requires knowledge about consequences.
