我需要用C ++做一些进程注入，但我会preFER用C＃的一切比低层次的东西等。我听说过功能包装和整编，并做了相当多的谷歌搜索和发现比特的信息在这里和那里，但我还是很缺乏。

I need to do some process injection using C++ but I would prefer to use C# for everything other than the low level stuff. I have heard about "function wrapping" and "marshaling" and have done quite a bit of google searching and have found bits of information here and there but I am still really lacking.

我如何包装所有低层次的东西（原生C ++）在C＃中，所以我可以很容易地命令我更舒服，C＃语言的功能呢？

How can I wrap all the lower level stuff (native C++) in C# so I can easily command those functions in a language I am more comfortable with, C#?

在主题的任何信息，多AP preciated。

Any information on the topic is much appreciated.

推荐答案

我想的P / Invoke是真正的最直接的方法：

I think P/Invoke is really the most straightforward approach:

创建一个DLL中的非托管的C ++中，包含了所有你需要做注射的功能。 在C＃code，声明一些静态外部方法，并使用的DllImport 属性指向他们到C ++ DLL。欲了解更多详细信息，请参阅 arul 中的他的回答。 Create a DLL in unmanaged C++, containing all the functionality you need to do the injection. In your C# code, declare some static extern methods, and use the DllImport attribute to point them to your C++ dll. For more details, see the link provided by arul in his answer.

注意的P / Invoke不限于Windows API函数＆mdash;你可以调用任何本机DLL导出的函数。

Note that P/Invoke isn't limited to "windows API functions" — you can call functions exposed by any native DLL.

P /调用的一个潜在缺点是，你必须提供签名的C ++函数，可能指定一些不那么明显的编组。在这种情况下，你可以考虑构建，而不是一个普通DLL COM服务器，并使用的 COM互操作调用从C＃的code。

A potential downside of P/Invoke is that you will have to provide the signatures for your C++ functions, possibly specifying some less-than-obvious marshalling. In that case, you could consider constructing a COM server instead of a "plain" DLL, and using COM interop to call your code from C#.
