C# – join() method

join():

• An instance method belongs to Thread class.
• It stops the current the thread execution until joined thread execution completes.

Example: Consider First thread is calculating sum of first N numbers and second thread has to display the result. The Second thread has to wait until First thread completes calculation.

using System; using System.Threading; public class Program {             public static int n;             static void Main(string[] args)             {                         Console.WriteLine(“Enter n value : “);                         Program.n = Convert.ToInt32(Console.ReadLine());                         Thread t = new Thread(new ThreadStart(Calculation.find));                         t.Start();                         t.Join();                         Console.WriteLine(“Sum of First : ” + n + ” numbers is : ” + Calculation.sum);             } }   public class Calculation {             public static int sum = 0;             public static void find()             {                         for(int i=1; i<=Program.n; i++)                         {                                     Calculation.sum = Calculation.sum + i;                         }             } }
