C#. Threads simple example

        static void Main(string[] args)
        {
           Console.WriteLine("inside thread id " + Thread.CurrentThread.ManagedThreadId);
           var otherThread = new Thread(ThreadWork);
           otherThread.Priority = ThreadPriority.Normal;
           otherThread.Start(5);
           otherThread.Join(); // wait for otherThread 
           Console.WriteLine("finish");
        }

        private static void ThreadWork(object obj)
        {
            Thread.Sleep(1000);
            Console.WriteLine("inside thread id " + Thread.CurrentThread.ManagedThreadId);
            Console.WriteLine("object is " + obj);
        }

Result will be like this

inside thread id 1
inside thread id 1
inside thread id 4
object is 5
finish
