Simple Complete Threading Demo C# with Example

class Program 
{ 
static void Main(string[] args) 
{ 
//  Create  2  thread  objects. We're using delegates because we need to pass 
// parameters to the threads. 
var thread1 = new Thread(new ThreadStart(() => PerformAction(1))); 
var thread2 = new Thread(new ThreadStart(() => PerformAction(2))); 
// Start the threads running 
thread1.Start(); 
// NB: as soon as the above line kicks off the thread, the next line starts; 
// even if thread1 is still processing. 
thread2.Start(); 
// Wait for thread1 to complete before continuing 
thread1.Join(); 
// Wait for thread2 to complete before continuing 
 

thread2.Join(); 
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("Thread: {0}: {1}", id, i); 
Thread.Sleep(rnd.Next(0, 1000)); 
} 
}
