DLL的C源代码以在C＃应用程序中使用 [英] C source code to DLL for use in a C# application

问题描述

我有一个用VC ++ 6.0编写的C源代码，我需要将该代码用于正在编写的C＃应用​​程序中。

I have a C source code written in VC++6.0 and I need that code to be used in a C# application which I am coding.

我已经完成了做到这一点的几件事，我已经在发布模式下运行了C源文件，并在其中生成了中间体.manifest文件和其他文件，我可以使用其中的任何文件来解决问题。

I have done few things to make that happen, I have run that C source file in release mode and have generated the intermediate.manifest file and the other files there, can I use any of these file to make my problem solved.

推荐答案

您要做的是导入dll ，如下所示：

What you want to do is import the dll like this:

 [DllImport("user32.dll")]//This is where you identify your dll...
   public static extern int MessageBoxA(  //This would be an object from your dll
      int h, string m, string c, int type);

   public static int Main() 
   {
      return MessageBoxA(0, "Hello World!", "My Message Box", 0);
   }

您需要搜索以了解此信息的关键字是运行非托管代码和 PInvoke 。

The keywords that you need to search on to learn about this are "running unmanaged code" and "PInvoke".
