Threading: 13- Multi-threading

When one programs uses multiple threads to accomplish its tasks, it is called multithreading.

Multithreading doesn’t guaranties the sequence of execution between threads.

Sample Code

using System;
using System.Threading;

// Multithreading

class Program {
    static void Main(string[] args) {
        Console.WriteLine("Main Started");
        var th1 = new Thread(Greet);
        th1.Start(new object[] { "Bob", "Good Morning" });
        var th2 = new Thread(Greet);
        th2.Start(new object[] { "John", "Good Morning" });
        Console.ReadKey();
    }

    private static void Greet(object info) {
        Console.WriteLine("Hi {0}, {1}!", (info as object[])[0], (info as object[])[1]);
        Console.WriteLine("\tThread Name: " + Thread.CurrentThread.Name);
        Console.WriteLine("\tThread Id: " + Thread.CurrentThread.ManagedThreadId);
        Console.WriteLine("\tIs Background: " + Thread.CurrentThread.IsBackground);
        Console.WriteLine("\tIs ThreadPool Thread: " + Thread.CurrentThread.IsThreadPoolThread);
        Console.WriteLine("\tIs Alive: " + Thread.CurrentThread.IsAlive);
        Console.WriteLine("\tPriority: " + Thread.CurrentThread.Priority);
        Console.WriteLine("\tThread State: " + Thread.CurrentThread.ThreadState);
    }
}

 

Output:

        Is Background: False
        Is ThreadPool Thread: False
        Is Alive: True
