在 C# 4.0 中，我们在 System.Threading.Tasks 命名空间中有 Task.Thread 和 Task 之间的真正区别是什么.为了自己学习

In C# 4.0, we have Task in the System.Threading.Tasks namespace. What is the true difference between Thread and Task. I did some sample program(help taken from MSDN) for my own sake of learning with

Parallel.Invoke 
Parallel.For 
Parallel.ForEach 

但有很多疑问，因为想法不是那么清楚.

but have many doubts as the idea is not so clear.

我最初在 Stackoverflow 中搜索了类似类型的问题，但可能由于这个问题标题我无法得到相同的问题.如果有人知道之前在这里发布的同一类型的问题，请提供链接的参考.

推荐答案

任务就是你想要完成的事情.

A task is something you want done.

线程是执行该任务的众多可能工作线程之一.

A thread is one of the many possible workers which performs that task.

在 .NET 4.0 术语中，任务代表异步手术.线程用于通过将工作分解为块并分配给单独的线程来完成该操作.

In .NET 4.0 terms, a Task represents an asynchronous operation. Thread(s) are used to complete that operation by breaking the work up into chunks and assigning to separate threads.
