C#使用来自DLL的虚空 [英] C# use a Void from A DLL

问题描述

当dllname在字符串中时，如何执行dll中的void?
为了使其更清楚一点:

字符串thisdll ="testdll.dll";
UseDLLOrSomething(thisdll)//我不知道如何从STRING导入dll
anyvoid();//我不知道如何从外部dll调用函数

有谁知道该怎么做?

PS:对不起，英语不好，那是因为我是荷兰人.

How can i execute a void from a dll when the dllname is in a string?
To make it a little clear:

string thisdll = "testdll.dll";
UseDLLOrSomething(thisdll)//i don''t know how to import a dll from a STRING
anyvoid();//I don''t know how to call a function from a extern dll

does anyone know how to do this?

PS: sorry for bad english, that is becouse i am dutch.

推荐答案

答案将取决于dll.如果是托管(.Net)，则只需调用:

The answer will depend on the dll. If it''s Managed (.Net) then you can simply call:

System.Reflection.Assembly.LoadFile("ddlFile");

然后使用反射调用该方法. (您可能还需要通过反射来实例化一个类).

如果是Native(例如c/c ++)，则需要通过DLLImport注册该函数.

And then use reflection to call the method. (you may need to instance a class via reflection as well).

If it''s Native (like c/c++) then you''ll need to register the function via a DLLImport.
