Differences Between Task And Thread In C# ?

How to create a Task:

1. static void Main(string[] args) {  
2.     Task < string > obTask = Task.Run(() => (  
3.         return“ Hello”));  
4.     Console.WriteLine(obTask.result);  
5. } 

How to create a Thread:

1. static void Main(string[] args) {  
2.     Thread thread = new Thread(new ThreadStart(getMyName));  
3.     thread.Start();  
4. }  
5. public void getMyName() {} 

Differences Between Task And Thread

 

Here are some differences between a task and a thread.

1. The Thread class is used for creating and manipulating a thread in Windows. A Task represents some asynchronous operation and is part of the Task Parallel Library, a set of APIs for running tasks asynchronously and in parallel.
2. The task can return a result. There is no direct mechanism to return the result from a thread.
3. Task supports cancellation through the use of cancellation tokens. But Thread doesn't.
4. A task can have multiple processes happening at the same time. Threads can only have one task running at a time.
5. We can easily implement Asynchronous using ’async’ and ‘await’ keywords.
6. A new Thread()is not dealing with Thread pool thread, whereas Task does use thread pool thread.
7. A Task is a higher level concept than Thread.
