C# Lock Statement

In this chapter you will learn:

• What is Lock Statement in C#?
• What is the benefit of using lock statement in C#?
• How to use it in C# programming?

The lock statement handles lock segment as a critical section and locks the object during the execution of the program from other thread. Once the execution is completed it releases the lock and frees objects.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Lock_Statement
{
    class Program
    {
        public void printname()
        {
            Console.WriteLine("My name is Steven Clark");
        }

        static void Main(string[] args)
        {
            Program p = new Program();
            // creating lock segment. all the resources that is used in lock segment, can't be used by another thread until it releases.
            lock (p)
            {
                p.printname();
            }
            Console.ReadLine();
        }
    }
}

Output

My name is Steven Clark
