Task

1. Using Task.Run

csharp

using System;

using System.Threading.Tasks;

class Program

{

    static async Task Main(string[] args)

    {

        await Task.Run(() => DoWork());

    }

    static void DoWork()

    {

        // Simulate some work

        Console.WriteLine("Work is being done...");

    }

}

2. Using Task.Factory.StartNew

csharp

using System;

using System.Threading.Tasks;

class Program

{

    static async Task Main(string[] args)

    {

        await Task.Factory.StartNew(() => DoWork());

    }

    static void DoWork()

    {

        // Simulate some work

        Console.WriteLine("Work is being done...");

    }

}

3. Using Task Constructor and Start Method

csharp

using System;

using System.Threading.Tasks;

class Program

{

    static async Task Main(string[] args)

    {

        var task = new Task(() => DoWork());

        task.Start();

        await task;

    }

    static void DoWork()

    {

        // Simulate some work

        Console.WriteLine("Work is being done...");

    }

}

4. Using Async and Await

csharp

using System;

using System.Threading.Tasks;

class Program

{

    static async Task Main(string[] args)

    {

        await DoWorkAsync();

    }

    static async Task DoWorkAsync()

    {

        // Simulate some work

        await Task.Delay(1000);

        Console.WriteLine("Work is being done...");

    }

}

5. Using Parallel.ForEach with Task

csharp

using System;

using System.Collections.Generic;

using System.Threading.Tasks;

class Program

{

    static async Task Main(string[] args)

    {

        var list = new List<int> { 1, 2, 3, 4, 5 };

        var tasks = new List<Task>();

        Parallel.ForEach(list, item =>

        {

            tasks.Add(Task.Run(() => DoWork(item)));

        });

        await Task.WhenAll(tasks);

    }

    static void DoWork(int item)

    {

        // Simulate some work

        Console.WriteLine($"Work is being done on item {item}...");

    }

}

These are just a few ways to run tasks in C#. Each method has its own use case, depending on your needs.

//============================================================

sample code for creating Task

static void Main(string[] args)

{

    Console.Write("(1.) Enter your name : ");

    string? name = Console.ReadLine();

    Task task = Task.Run(() => MyMethod("2.",name));

    task.Wait(); // Wait for the task to complete

    TestingClass objTest=new TestingClass();

    Task<string> testTask = Task.Run(()=>objTest.PrintMessageReturnSum(5,10,"(3.) "));

    Console.WriteLine(testTask.Result);

    if (name.ToLower().Contains("jobin"))

    {

        Task lastTask = new Task(() => MyMethod("4.", "jose"));

        lastTask.Start();

    }

    else if(name.ToLower().Contains("jose"))

    {

        Task lastTask = new Task(() => MyMethod("4.", "sam"));

        lastTask.Start();

    }

    Task<string> retTask =  Task.Factory.StartNew<string>(()=>objTest.TaskFactory("(last) end of all Tasks"));

    Console.WriteLine(retTask.Result);

    //----------------------------

    Console.ReadKey();
