如何从加载的DLL管理类？ [英] How to manage classes from a loaded DLL?

问题描述

如何将类转换成一个变量来调用函数并获取属性？

我被告知要查看反射，但是当DLL未知时，我不知道如何完成编译时间。

How can I get a class into a variable to call function and get properties?
I have been told to look into reflection but I don't get how it's done when the DLL was not known at compile time.

要清楚：我有一个'main'类加载一个DLL，我想在DLL中创建一个类的实例，并直接获取属性

To be clear: I have a 'main' class which loads an DLL and I want to create an instance of a class within the DLL and directly get properties.

推荐答案

你应该这样做：

Assembly asm = Assembly.Load("DLL File Path"); //load DLL from file
Type t = asm.GetType("Test.ExternalDllTest"); //fully qualified name
dynamic oDynamic = Activator.CreateInstance(t, args);//create an instance of specified type, and assign it to DYNAMIC object

编辑

 oDynamic.SomeMethod(); //call the method of your type. Being DYNAMIC it will route the call to correct method.

自然地， DLL 必须是托管DLL （所以写在 .NET 语言）

Naturally, the DLL has to be a managed DLL (so written in .NET language)

我没有编译这个老实说，但基本上这是一个如何做的想法。

I didn't compile this, honestly, but basically this is an idea of how to do that.

这里还有一个示例，这可能有帮助。

Here also an example, that may help.
