如何使用Reflection访问内部类 [英] How to access internal class using Reflection

问题描述

如何访问程序集的内部类？
说我想访问System.ComponentModel.Design.DesignerHost。这里的DesignerHost是一个内部和密封的类。

如何编写代码来加载程序集和类型？

解决方案

一般来说，不应该这样做 - 如果一个类型已被标记为内部，这意味着你不打算从程序集之外使用它。

但是，反射 允许您访问不公开的类型和成员 - 只是寻找重载，它需要一个 BindingFlags 参数，并包括 BindingFlags.NonPublic 在你传递的标志。 / p>

如果您具有类型的完全限定名称（包括程序集信息），则只需调用 Type.GetType（string） 应该可以正常工作。如果您事先知道程序集，并且知道该程序集中的公共类型，那么使用 typeof（TheOtherType）.Assembly 来获取程序集引用通常比较简单，可以调用 Assembly.GetType（string） 。

How can I access an internal class of an assembly? Say I want to access System.ComponentModel.Design.DesignerHost. Here the DesignerHost is an internal and sealed class.

How can I write a code to load the assembly and the type?.

解决方案

In general, you shouldn't do this - if a type has been marked internal, that means you're not meant to use it from outside the assembly. It could be removed, changed etc in a later version.

However, reflection does allow you to access types and members which aren't public - just look for overloads which take a BindingFlags argument, and include BindingFlags.NonPublic in the flags that you pass.

If you have the fully qualified name of the type (including the assembly information) then just calling Type.GetType(string) should work. If you know the assembly in advance, and know of a public type within that assembly, then using typeof(TheOtherType).Assembly to get the assembly reference is generally simpler, then you can call Assembly.GetType(string).
