Multithreading
Summary
Thread、ThreadPool、Task、Parallel
From the timeline of technology development, Microsoft launched these in the following order: Thread=>ThreadPool=>Task=>Parallel
Thread
The advantage is that it provides a rich multi-threaded operation API, but the disadvantage is that the number of threads is not limited, and the threads cannot be reused, so the TheadPool technology is introduced
ThreadPool
The advantage is that the limitation of the number of threads and the reuse of threads are solved, but the disadvantage is that there are fewer APIs and the thread waiting problem is more troublesome to solve, so the Task technology is introduced
Task
The advantage is that the rich API and the convenient management of multiple threads, but the disadvantage is that the number of threads is more troublesome, so the Parrel technology is introduced
Parallel
The advantage is that the rich API, multi-threading is easy to manage, and the number of threads is simple to control, but the main thread will also participate in the calculation, resulting in the blocking problem of the main thread (but this problem can be solved by wrapping a layer)
