cli / C ++如何定义cli :: array与非托管类型元素？ [英] cli/C++ how to define cli::array with unmanaged type element?

问题描述

我有一个原生的C / C ++结构

I have a native C/C++ struct

typedef struct
{
...
} AStruct;

并且在C ++ / CLI代码中定义一个委托和一个cli数组如下

and in C++/CLI code i define one delegate and one cli array as following

public delegate void UpdateDataDelegate(AStruct% aSt,AStruct% bSt);

cli::Array<AStruct>^ args=gcnew cli::Array<AStruct>(2); // complile failed!!!!。

this->Invoke(updateData,args);

AStruct 有许多字段，许多模块，所以如果我不喜欢为 AStruct 写一个mananged包，如何使上面的代码工作？

AStruct has many fields and was used by many modules so if i don't like to write a mananged wrap for AStruct, how to make above code works?

非常感谢。

推荐答案

托管数组的元素类型必须是托管类型。一种解决方法是存储指针：

The element type of a managed array must be a managed type. One workaround is store pointers:

array<AStruct*>^ args=gcnew array<AStruct*>(2);
args[0] = new AStruct;
// etc...

UpdateDataDelegate^ dlg = gcnew UpdateDataDelegate(Mumble);
dlg->Invoke(*args[0], *args[1]);
