什么是Process.Dispose（）实际上做？

问题描述

在C＃类工艺从继承类组件实现的IDisposable 键，这样我就可以叫的Dispose（）任何进程对象。难道我真的有什么打算？我怎么知道，如果我真的有什么打算？

假设我有以下的code：

  VAR allProcesses = System.Diagnostics.Process.GetProcesses（）;
 VAR processesNames = processes.Select（P =＆GT; p.ProcessName）;
 //输出过程在这里的名字
 

现在它看起来像我有进程对象的数组，我有手艺一个尝试，终于穿越阵列和的Dispose（）每个对象。这绝对是许多额外的code。

什么叫的Dispose（）做进程的对象？难道我真的需要的Dispose（）每个进程对象，我怎么决定，如果我必须这样做？

解决方案

是的，你应该释放他们。注意在文档中该文本<$c$c>Process:

所以，如果你不这样做处置他们，你可能泄漏手柄（直到他们垃圾回收 - 但整点处置就是让资源早期清理）

请注意，同时，同一文件表明，进程覆盖的Dispose（布尔） - 另一条线索，这实际上做的的东西的时候处置之称。

In C# class Process inherits from class Component that implements IDisposable and so I can call Dispose() on any Process object. Do I really have to? How do I know if I really have to?

Suppose I have the following code:

 var allProcesses = System.Diagnostics.Process.GetProcesses();
 var processesNames = processes.Select( p => p.ProcessName );
 // output process names here

Now it looks like I have an array of Process objects and I have craft a try-finally to traverse the array and Dispose() each object. That's definitely lots of extra code.

What does that Dispose() do for Process objects? Do I really need to Dispose() every Process object and how do I decide if I need to do so?

解决方案

Yes, you should dispose them. Note this text in the documentation for Process:

So if you don't Dispose them, you're potentially leaking the handles (until they're garbage collected - but the whole point of Dispose is to allow early cleanup of resources)

---

Note, also, that the same documentation indicates that Process overrides Dispose(bool) - another clue that it actually does something when Dispose is called.
