Refer to the System.Threading namespace on MSDN for full details. Meanwhile here is a quick taste.

using System; 
using System.Threading; 

class ThreadTest 
{ 
    public void Runme() 
    { 
        Console.WriteLine("Runme Called"); 
        Thread.Sleep(10000); 
    }

    public static void Main(String[] args)
    { 
        ThreadTest b = new ThreadTest(); 
        Thread t = new Thread(new ThreadStart(b.Runme)); 
        t.Start(); 

        Console.WriteLine("Thread 't' started.");
        Console.WriteLine("There is no telling when " + 
                          "'Runme' will be invoked. "); 

        t.Join(); 

        Console.WriteLine("Thread 't' has ended."); 
    }
}
