如何从GAC加载程序集？ [英] How would I load an assembly from the GAC?

问题描述

我正在尝试使用Assembly.Load（）加载GAC中的程序集。例如，说我想列出 PresentationCore.dll 中存在的所有类型，我该如何加载 PresentationCore.dll ？

当我尝试以下操作时：

  Assembly a = Assembly.Load（ PresentationCore.dll ）; 
  

我收到 FileNotFoundException 。

I'm trying to use Assembly.Load() to load an assembly that is in the GAC. For example, say I want to list out all of the types that exist in PresentationCore.dll, how would I go about loading PresentationCore.dll?

When I try this:

Assembly a = Assembly.Load("PresentationCore.dll");

I get a FileNotFoundException. Another answer on SO suggested I used Assembly.LoadFrom() to accomplish this - I'm hesitant to do that because Assembly.LoadFrom() is deprecated, according to Visual Studio 2008 - plus, it doesn't seem to actually work.

Any ideas?

解决方案

If the assembly is in the GAC you must load it via its fully qualified name.

For example, if I wanted to load mscorlib.dll I would do something like this:

Assembly a = Assembly.Load
    ("mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089");

The easiest way to determine an assembly's fully qualified name is to load the assembly in Reflector and use the Name field from the lower display pane like this:
