C#中的结构指针 [英] Structure pointer in C#

问题描述

我有C ++库.我想在C#项目中使用它.我需要将链接列表传递给C ++函数.我的C ++结构是这样的:

Hi,
I have C++ library. I want to use it in C# project. I need to pass linked list to C++ function. My C++ structure is like this:

struct Node
{
   char data[];
   struct Node *next;
};

每当我创建具有该结构的对象时，下一个指针将必须指向先前创建的节点.这就是链表的形成方式，但是当我试图用C#这样编写不安全的结构时:

Every time when I create an object of that structure, the next pointer will have to point to the previously created node. This is how a linked list will be formed, but when I am trying to write unsafe struct in C# like this:

[StructLayout(LayoutKind.Sequential)]
unsafe struct Node
{
   char [] data = new char[10];
   struct Node *next;
};

在结构内部声明结构指针时出现错误

I am getting an error while declaring the structure pointer inside the structure

Error - The type or namespace name "next" could not be found

如果我在编组邮件时想念什么，请告诉我.

谢谢

Please let me know if i am missing something while marshaling.

Thank you,

推荐答案

您不需要在声明内使用struct关键字-只需Node *部分:

You don''t need the struct keyword inside the declaration - just the Node* part:

[StructLayout(LayoutKind.Sequential)]
unsafe struct Node
{
   char [] data = new char[10];
   Node *next;
};
