如何找到所有类implemeting IDisposable的？ [英] How to find all Classes implemeting IDisposable?

问题描述

我工作的一个大项目，我的任务之一是消除可能的内存泄漏。在我的代码，我注意到没有被设置的几个IDisposable的项目，并有固定的。然而，这使我更基本的问题，我怎么发现的使用的所有类在我的项目，该项目实现IDisposable？ （不，已经使用自定义创建的类，但标准库类）。

我已经找到了一个实现IDisposable（数据表工具MarshalByValueComponent，它继承了IDisposable）低于显而易见类。现在，我手动检查任何可疑类通过MSDN，而不是有一些方法，通过它我可以自动完成这一过程？

I am working on a large project, and one of my tasks is to remove possible memory leaks. In my code, I have noticed several IDisposable items not being disposed of, and have fixed that. However, that leads me to a more basic question, how do I find all classes used in my project that implement IDisposable? (Not custom-created classes but standard Library classes that have been used).
I have already found one less-than-obvious class that implements IDisposable ( DataTable implements MarshalByValueComponent, which inherits IDisposable). Right now, I am manually checking any suspected classes by using MSDN, but isn't there some way through which I can automate this process?

推荐答案

反射可以告诉你哪些类实现的IDisposable ：刚刚找到在反射器的的IDisposable 接口，并展开派生类型节点。

Reflector can show you which classes implement IDisposable : just locate the IDisposable interface in Reflector, and expand the "Derived types" node

另一种选择，从代码中，是扫描所有加载的程序集实现类型的IDisposable ：

Another option, from code, is to scan all loaded assemblies for types implementing IDisposable :

var disposableTypes =
    from a in AppDomain.CurrentDomain.GetAssemblies()
    from t in a.GetTypes()
    where typeof(IDisposable).IsAssignableFrom(t)
    select t;
