通过dll为vb.net导出C ++类 [英] Export C++ Class through dll for vb.net

问题描述

以allah的名义



玩得开心



摘要我想发送给我自己的类（用c ++）到vb.net，这样在vb.net中我就可以使用那个类了，它的子结构，类，变量，函数，....

i在Google中搜索了很多，msdn.microsoft，codeproject，stackoverflow，...这样做，但我不能。最后我在OCXActiveX项目上工作，部分工作，而不是完全。例如在activeX项目中，我无法访问子类和...来自vb.net。

我错了还是不可能来自activeX？



你可以帮帮我吗？



提前谢谢

解决方案

为什么不呢只是将C ++类构建为CLR DLL程序集并直接从VB代码引用该类？这样C ++类就是一个.NET类，您可以在VB应用程序中对它进行处理。

Griff的响应绝对是可行的方法。



按如下方式更改代码：

  namespace  mydll 
 {
  public   ref  类 class1 
 {
  public ：
 
 class1（）
 { 
 inside =  gcnew  class2; 
} 
 
  ref   class  class2 
 {
  public ：
 
  int  x; 
} 
里面; 
}; 
}; 

inside成为类型为class2的成员变量。你的vb.net代码如下所示：

  dim  a  as   new  mydll.class1 
 a.inside.x = 4 

in the name of allah

have a good time

in summary i want send my own class (in c++) to vb.net so that in the vb.net i can use that class and it's sub structs,class,variables,functions,... .
i searched a lot in google,msdn.microsoft, codeproject,stackoverflow ,... for doing this, but i couldn't. at finally i worked on "OCX" ActiveX project and work partly , not completely. for example in the activeX project i couldn't access the sub class and ... from vb.net.
do i was wrong or it's impossible from activeX?

can you help me ?

thanks in advance

解决方案

Why not just build the C++ class as a CLR DLL assembly and reference the class directly from your VB code? That way the C++ class is a .NET class and you can treat it as such in your VB application.

Griff's response is definitely the way to go.

Change your code as follows:

namespace mydll
{
    public ref class class1
    {
        public:

        class1()
        {
            inside = gcnew class2;
        }

        ref class class2
        {
            public:

            int x;
        }
        inside;
    };
};

"inside" becomes the member variable whose type is class2. Your vb.net code would look like this:

dim a as new mydll.class1
a.inside.x=4
