In this article I’m explaining about Creating, Managing and destroying threads in

c#.

if you learn more  about Thread Synchronization read my previous post Thread

Synchronization in c#

Creating Threads:

Threads are created by extending the Thread class. The extended Thread class then

calls the Start () method to begin the child thread execution.

using System.Threading;
 
namespace ThreadManaging
{
    class Program
    {
        public static void ThreadB()
        {
            Console.WriteLine("Thread B Starts");
        }
        static void Main(string[] args)
        {
            ThreadStart thread = new ThreadStart(ThreadB);
            Console.WriteLine("In Main Thread: Creating the Thread B");
            Thread childThread = new Thread(thread);
            childThread.Start();
            Console.ReadKey();
        }
    }
}

Output

Managing Threads:

The Thread class provides various methods for managing threads. The following

example demonstrates the use of the sleep () method for making a thread pause

for a specific period of time.

using System.Threading;
 
namespace ThreadManaging
{
    class Program
    {
        public static void ThreadB()
        {
            Console.WriteLine("Thread B Starts");
            int sleep = 10000;
            Console.WriteLine("Thread B Paused for {0} Seconds",sleep/1000);
            Thread.Sleep(sleep);
            Console.WriteLine("Thread B Resumes");
        }
        static void Main(string[] args)
        {
            ThreadStart thread = new ThreadStart(ThreadB);
            Console.WriteLine("In Main Thread: Creating the Thread B");
            Thread childThread = new Thread(thread);
            childThread.Start();
            Console.ReadKey();
        }
    }
}

Output

Destroying Threads:

The Abort () method is used for destroying threads. The runtime aborts the thread

by throwing a ThreadAbortException. This exception cannot be caught, the control

is sent to the finally block, if any.

using System.Threading;
 
namespace ThreadManaging
{
    class Program
    {
        public static void ThreadB()
        {
            try
            {
                Console.WriteLine("Thread B Starts");
                for (int i = 0; i <= 10; i++)
                {
                    Thread.Sleep(500);
                    Console.WriteLine(i);
                }
                Console.WriteLine("Thread B Completed");
            }
            catch (ThreadAbortException e)
            {
                Console.WriteLine("Thread Abort Exception" + e.Message);
            }
            finally
            {
                Console.WriteLine("Could not catch the Thread Exception");
            }
 
        }
 
        static void Main(string[] args)
        {
            ThreadStart threadstart = new ThreadStart(ThreadB);
            Console.WriteLine("In Main Thread: Creating the Thread B");
            Thread thread = new Thread(threadstart);
            thread.Start();
            Thread.Sleep(2000);
            Console.WriteLine("In Main Thread: Aborting the  Thread B");
            thread.Abort();
            Console.ReadKey();
        }
    }
}
