use of Thread Sleep method in C sharp

Thread.Sleep a method used to suspend current thread for a specific interval of time. Time can be specified in milliseconds.
While in a Sleep mode a method does not consumes any CPU resources so indirectly it save memory for other thread processes.

On the same we will create a simple example where in the for loop while printing output we will make a thread to sleep for 1000 milliseconds i.e. 1 sec for per print.

 C# Thread program example using Sleep method

Code

using System;
using System.Threading;
using System.Threading.Tasks;

class Program
    {
        static void Main(string[] args)
        {
            Thread t1 = new Thread(PrintEven);
            Thread t2 = new Thread(PrintOdd);

            t1.Start();
            t2.Start();
            t2.Join();
        }

        static void PrintEven()
        {
            for (int i = 0; i <= 10; i=i+2)
            {
                Console.WriteLine(i);
                Thread.Sleep(1000);
            }
        }

        static void PrintOdd()
        {
            for (int i = 1; i <= 10; i = i + 2)
            {
                Console.WriteLine(i);
                Thread.Sleep(1000);
            }
        }
    }

As you see from above example we have implemented Sleep method in a PrintEven and PrintOdd methods and made thread to sleep for 1 sec for each print.

Output:

Main thread started
Printing the Number sequence 1 to 10
0
1
2
3
4
5
6
7
8
9
10
Main Thread Ended

If we observe the above output in the console of c# application, it will take one sec gap for printing digit after digit.
