在C ++中创建一个.dll以与C＃一起使用 [英] Create a .dll in C++ to be used with C#

问题描述

我有.lib文件和.header文件，用C ++编写。我想要一个相同的编译.dll。

如何使用它来构建.dll。创建.dll文件之后我需要在C＃项目中使用它。我试过但是每当在我的C＃项目中添加引用时它都显示错误。



任何人都可以帮助我



谢谢。

推荐答案

您可以使用常规C ++ DLL并通过P / Invoke通过.NET程序集（C＃或非C）使用它，或者您可以使用C ++ / CLI并以常规方式生成常规.NET程序集和使用，通常由C＃程序集引用它。



或者，您甚至可以创建混合模式（托管+非托管）C ++ / CLI DLL项目。从.NET程序集的角度来看，这样的项目将生成一个常规的.NET程序集，您也可以引用它。

You can either use regular C++ DLL and use it by a .NET assembly (C# or not) through P/Invoke, or you can use C++/CLI and produce regular .NET Assembly and use in a usual way, typically, reference it by your C# assembly.

Alternatively, you can even create mixed-mode (managed+unmanaged) C++/CLI DLL project. From the standpoint of a .NET assembly, such project will produce a regular .NET assembly which you can reference as well.

对于非托管c ++ dll，你必须使用dllimport：

参见此示例：



C#/C与DllImport互操作 [ ^ ]

For an unmanaged c++ dll you must use dllimport:
