为什么3线程的基本单线程C＃控制台应用程序？ [英] Why 3 threads for a basic single threaded c# console app?

问题描述

我创建了C＃中的控制台应用程序有一个到Console.ReadLine 语句。运行Visual Studio中这个程序，并步入调试器显示7线程的线程窗口（6工作者线程，一个是.NET SystemEvents，另一个是 vshost.RunParkingWindow 和主线程）。

I created a console app in c# with a single Console.ReadLine statement. Running this app within Visual Studio and stepping into the debugger shows 7 threads in the thread window (6 worker threads, one is .NET SystemEvents and the other is vshost.RunParkingWindow and the main thread).

当我运行Visual Studio以外的应用程序，我一共有3个线程在Windows任务管理器中看到。为什么有这么多的时候我会想到1个线程？什么是其他人则催生了？

When I run the app outside Visual Studio I see a total of 3 threads in Windows task manager. Why so many when I would expect 1 thread? What are the others being spawned for?

推荐答案

如果你正在运行一个.NET应用程序，我相信你总能得到一个线程（主要是睡觉）的JIT（刚刚在即时编译器）作为还有GC（垃圾回收）线程，除了你的主线程。

If you're running a .NET application, I believe you always get a thread (mostly sleeping) for the JIT (Just-in-Time compiler) as well as the GC (Garbage Collection) thread, in addition to your main thread.
