在C#库和C ++(CLR)之间传递对象 [英] Passing objects between C# library and C++ (CLR)

问题描述

如何将对象从C#库传递到C ++.

How to pass objects from C# library to C++.

我可以调用一个返回void或int的函数，而不会出现任何问题.

I can call a function which returns void or int without any issue.

现在考虑在C#中使用以下功能，

Now consider the following function in C#,

List<CSharpClass> CSharpFunction(string Input)

我的C#类包含的位置

public class CSharpClass
{ 
    string mystring = string.Empty;
    byte[] bytearray = null;        

    public byte[] bytearray 
    {
        get { return bytearray ; }
        set { bytearray = value; }
    }

    public string mystring 
    {
        get { return mystring ; }
        set { mystring = value; }
    }      
}

现在，我想在我的C ++中使用此列表.所以我创建了，

Now, I want use this List in my C++. So I have created,

  typedef std::vector<class CSharpClass>  MyDetailList;

这是正确的方法吗?如果不是，我需要在C ++中使用什么?

Is it the right way ?? If not what I need to use in C++?

推荐答案

如果要从C ++代码调用C#dll，可以遵循

If you want to call a C# dll from C++ code, you can follow this article. In a nutshell, you're going to have to:
- Write a Managed DLL containing your CSharpClass
- Register the Managed DLL for Use with COM or with Native C++
- Call the Managed DLL from Native C++ Code

此SO问题也很重要，并且包含替代解决方案如果要避免使用COM

This SO question is also relevant, and contains alternative solutions if you want to avoid using COM

最初的误导答案:

您可以查看这篇文章以获得不错的教程. 简而言之，您将必须:
-从您的C ++代码中编译一个DLL
-在C#和C ++之间进行marshall(翻译")您的类
-使用DllImport声明从C#加载dll
-调用导入的方法

You can check this article for a fairly good tutorial. In a nutshell, you're going to have to:
- Compile a dll from your c++ code
- marshall ("translate") your class between C# and C++
- load the dll from C#, by using DllImport declaration
- call the imported method
