Simple Complete Threading Demo using Tasks C# with Example

class Program 
{ 
static void Main(string[] args) 
{ 
// Run 2 Tasks. 
var task1 = Task.Run(() => PerformAction(1))); 
var task2 = Task.Run(() => PerformAction(2))); 
// Wait (i.e. block this thread) until both Tasks are complete. 
Task.WaitAll(new [] { task1, task2 }); 
Console.WriteLine("Done"); 
Console.ReadKey(); 
} 
 

// Simple method to help demonstrate the threads running in parallel. 
static void PerformAction(int id) 
{ 
var rnd = new Random(id); 
for (int i = 0; i < 100; i++) 
{ 
Console.WriteLine("Task: {0}: {1}", id, i); 
Thread.Sleep(rnd.Next(0, 1000)); 
} 
} 
}
