THREAD LOCKING C#

c# thread lock

C# THREAD LOCK  

“C# thread lock is a process of locking of block of codes or resource to preventing the access of multiple threads for a same resource at a point of time”. 

    C# thread lock process play very important rule in multithreading ,when multiple user trying to access for a same resources of Data in Data Base System and Web Server System at a time.

Syntax of Thread locking

               To lock the blocks of code we use the keyword ‘Lock (this)’ and place the codes 

in-between starting and closing braces like given below, now once you lock the codes then that is accessable for only one thread at a time all the other thread have to wait in line to get acess to thoes code which is locked. C# thread lock syntax is

Lock (this)

{

  Statements;

  Or block of codes;

}

EXAMPLE OF THREAD LOCKING

            Suppose an example. That has a lock method accessing by different thread, make sure to add directive above of namespace that is ‘System. Threading’.

using System.Threading;

namespace ThraedLock

{

    class Program

    {

        public void ThreadLockdemo()

        {

            lock (this)

            {

                for (int i = 1; i <= 50; i++)

                    Console.WriteLine("Printing line number " + i );

            }

        }

        static void Main(string[] args)

        {

            Program p = new Program();

            Thread t1 = new Thread(p.ThreadLockdemo);

            Thread t2 = new Thread(p.ThreadLockdemo);

            Thread t3 = new Thread(p.ThreadLockdemo);

            t1.Start();

            t2.Start();

            t3.Start();

            Console.ReadKey();

        }

    }

}

       This program will program the line in sequence otherwise without using lock threading sequence will disturbed run it and see the outputs and then remove the lock body and see the output you will notice the changes.
