获取类型的GUID [英] Get type from GUID

问题描述

由于种种原因，我需要实现在C＃中的类型缓存机制。幸运的是，CLR提供 Type.GUID 来唯一标识一个类型。不幸的是，我无法找到任何方式来查找基于此GUID的类型。有 Type.GetTypeFromCLSID（）但根据我的理解的文档（和实验）中，做一些非常，非常不同的。

For various reasons, I need to implement a type caching mechanism in C#. Fortunately, the CLR provides Type.GUID to uniquely identify a type. Unfortunately, I can't find any way to look up a type based on this GUID. There's Type.GetTypeFromCLSID() but based on my understanding of the documentation (and experiments) that does something very, very different.

有没有什么办法让基础上，通过对所有类型的负载循环和比较他们的GUID的GUID短类型？

Is there any way to get a type based on its GUID short of looping through all the loaded types and comparing to their GUIDs?

修改：我忘了提，我真的像一个型指纹固定宽度的，这就是为什么GUID是如此吸引我。当然，在一般情况下，该类型的全名是可行的。

EDIT: I forgot to mention that I would really like a "type fingerprint" of fixed width, that's why the GUID is so appealing to me. In a general case, of course, the fully qualified name of the type would work.

推荐答案

不要循环比较。填充词典＆LT;类型＆GT; 并使用包含方法

Don't loop to compare. Populate a Dictionary<Type> and use the Contains method.

Dictionary<Type> types = new Dictionary<Types>();
... //populate 

if (types.Contains(someObject.GetType())) 
  //do something

这必将给你一​​个固定大小的入口，因为所有的人都将是对象引用（类型的实例本质上是工厂对象）。

This will certainly give you a fixed size entry, since all of them will be object references (instances of Type essentially being factory objects).
