如何使用方法从C ++ DLL在C#中枚举 [英] How to use methods & enum in c# from c++ DLL

问题描述

我有两个用c ++编写的dll.它具有枚举，方法，属性等.
我想在c#应用程序中使用它们.
因此，我应该怎么做?

I have two dll''s which are written in c++.It has enum ,method,properties etc..
I want to use them in c# application.
So what I should do?

推荐答案

如果这是纯本地C ++(不是C ++/CLI)，则只能将方法与P/Invoke一起使用.请参阅:
http://en.wikipedia.org/wiki/P/invoke [ http://msdn.microsoft.com/library/en-us/vcmxspec/html/vcmg_PlatformInvocationServices.asp [^ ].

If this is purely native C++ (not C++/CLI), you can use only the method with P/Invoke. Please see:
http://en.wikipedia.org/wiki/P/invoke[^],
http://msdn.microsoft.com/library/en-us/vcmxspec/html/vcmg_PlatformInvocationServices.asp[^].

Sometimes you need much tighter integration. In this case, another approach could be beneficial: using C++/CLI and mixed-mode (managed + unmanages) project. Such project can use everything in C++ resources, as much as regular C++ could use, and all CLI types and members to the project, some of them wrapping unmanaged code. This way, you can create a class library using native C++, but used as a regular .NET assembly. You can reference this assembly as any other .NET assembly in your C# projects. Please see:
http://en.wikipedia.org/wiki/C%2B%2B/CLI[^],
http://www.gotw.ca/publications/C++CLIRationale.pdf[^],
