获取功能列表的一个DLL [英] Get a list of functions for a DLL

问题描述

我要建一个项目。它的用户可以添加自己的扩展（DLL文件）的应用程序。要管理的延伸，我需要的类，它的功能列表等是否有code这样做呢？

I'm building a project. It's an application that users can add their extensions (DLL files) to. To manage an extension, I need to get its list of classes, functions, etc. Is there code for doing it?

注：我使用C＃

推荐答案

对于特定的组件，你可以使用<一个href="http://msdn.microsoft.com/en-us/library/system.reflection.assembly.gettypes.aspx"><$c$c>Assembly.GetTypes得到的类型，则对于每个类型的呼叫<一href="http://msdn.microsoft.com/en-us/library/system.type.getmethods.aspx"><$c$c>Type.GetMethods(), <一href="http://msdn.microsoft.com/en-us/library/system.type.getproperties.aspx"><$c$c>Type.GetProperties()等，或只是<一href="http://msdn.microsoft.com/en-us/library/system.type.getmembers.aspx"><$c$c>Type.GetMembers().

For a particular assembly, you can use Assembly.GetTypes to get the types, then for each type call Type.GetMethods(), Type.GetProperties() etc, or just Type.GetMembers().

不过，对于插件的功能，它通常有一个共同的接口，该插件必须执行一个好主意 -​​ 可以减少反射，你需要使用量。使用<一个href="http://msdn.microsoft.com/en-us/library/system.type.isassignablefrom.aspx"><$c$c>Type.IsAssignableFrom()检查一个类型是否是与特定的接口兼容。

However, for plugin functionality it's usually a good idea to have a common interface which the plugins have to implement - that reduces the amount of reflection you need to use. Use Type.IsAssignableFrom() to check whether a type is compatible with a particular interface.

You might also want to look at the Managed Extensibility Framework which can make implementing an extension system easier.
