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);  

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.
