如何在程序集加载时在程序集中运行某些代码，即可以自定义.net程序集入口点? [英] How to run some code in an assembly when it being load, ie can I customize .net assembly entrypoint?

问题描述

Dll的入口点名为DllMain.我们可以在此函数中编写一些代码来执行一些操作 初始化作业，例如初始化库的私有堆.

Dll's  developed by VC++ have entry point named DllMain. We can write some code in this function to do some initialization job, like initialize library's private heap.

现在，我希望一些代码在.NET程序集加载时运行.  可能吗?

Now, I want some code to run at a .NET assembly load time.  Does it possible?

推荐答案

我相信DllMain仍将在程序集中或至少在Windows平台上运行.但是DllMain必须以本机代码实现，不能调用托管代码，并且会限制可移植性.

I believe DllMain will still work in an assembly, or at least on a windows platform. But the DllMain must be implemented in native code, will not be able to call into managed code and will constrain portability.

在托管代码中最接近DllMain的是模块构造函数(在'< module>'类上具有特殊名称'.cctor'的方法).我不了解VB，但C ++/CLI和ilasm支持生成模块构造函数，但C#却不支持.

The closest thing to DllMain in managed code is the module constructor (a method with the special name '.cctor' on the '<module>' class). I don't know about VB, but C++/CLI and ilasm support generating a module constructor but C# does not.
