Threads basics and using ParameterizedThread

implementing multi threading and async process on c# 

Just imagine CPU  can process only one process at a time when we are working on Long running operations all other operation should wait until the first process complete, 

The remedy for this issue Threading introduced by using threads each thread can complete its own work with out depending or wait for other thread. 

certain time period current thread should pause and starts the other thread, 

 creating a thread with thread class

class Program
    {
        #region Threads
        public static void Thredmethod()
        {
            for (int i = 0; i < 10; i++)
            {
                Console.WriteLine("Sub process" + i);
                Thread.Sleep(5);
            }
        }
        public static void Mainthread(){
            Thread t = new Thread(new ThreadStart(Thredmethod));
            t.Start();
            for (int i = 0; i < 5; i++)
            {
                Console.WriteLine("main Thread :"+i);
            }
        }

                Thread.Sleep(1000);
            }
