通过C ++/CLI包装函数从C#引用非托管.LIB文件 [英] Referring unmanaged .LIB file from C# through C++/CLI wrapper function

问题描述

我有一个使用本机C ++编写的SDK .lib.我想编写一个C#应用程序以使用本机C ++库中提供的功能.
正如我在网上找到的解决方法是通过以下方式纠正我，如果我错了

1.需要使用C ++/CLI文件为该.lib文件编写包装函数，并创建一个DLL.

2.从C#应用程序中引用此DLL并获得结果.

请确认以上方式对吗?如果可以，我们可以通过VC ++编写包装器吗?是否仅需要通过C ++/CLI编写?

需要一些在C ++/CLI上编写包装函数的示例.

谢谢，

Hi,

I have a SDK .lib which is written on native C++. I want to write a C# application to use the functions available in the native C++ library.
As I found in the net The solution is in the following way, correct me If I am wrong

1. Need to write a wrapper function for that .lib file using C++/CLI file and creat a DLL.

2. Refer this DLL from C# application & achieve the result.

Please confirm the above way is right ? If yes can we write a wrapper through VC++ / do we need to write only through C++/CLI ?

Need some sample on writing a wrapper function on C++/CLI .

Thanks,
Pattabi

这是真实的.您将需要在C ++中创建一个新的托管类库(新建>项目> Visual C ++> CLR>类库").在此类库中，您将需要添加对.lib文件的引用.最后，您将必须定义并创建一个公共引用类"，以包装非托管代码的功能.不要忘记添加定义.lib函数的头文件的包含路径.

This is true. You will need to create a new managed class library in C++ (New > Project > Visual C++ > CLR > Class Library). In this class library you will need to add a reference to the .lib file. Finally, you will have to define and create a "public ref class" that wraps the functionality of the unmanaged code. Don''t forget to add the include path of the header file that defines the .lib function.

要从C#引用C ++/CLI类，可以添加对C ++项目的引用.我也喜欢将两个项目都放在同一个解决方案中.您还可以构建C ++ DLL(类库)并直接引用DLL.

To reference the C++/CLI class from C# you can add a reference the C++ project. I also like to have both projects in the same solution. You can also build the C++ DLL (class library) and refernce the DLL directly.

只需在C ++ ref类和对非托管代码的函数调用主体中创建一个公共方法(如果愿意，可以使用静态方法).

Just create a public method (static if you like) in your C++ ref class and in the body of the function call to the unmanaged code.

是的.您必须编写一个非托管DLL，然后在托管程序集中使用InteropServices才能获得DLLs功能.

Yes. You have to write an unmanaged DLL, and then use InteropServices in your managed assembly to get to the DLLs functionality.

感谢您的回复.您能否提供示例代码/链接?

Hi,

Thanks for your reply. Could you please give sample code/ link for it ?
