求:c#结构体内数组以及结构体嵌套

[axia_T]

/*结构体原型
typedef struct {
unsigned int s;
unsigned int d;
unsigned int SP[4][4];
} A;

typedef struct {
unsigned char mv;
unsigned char n;
B sb;
unsigned int cn;
unsigned int Seg[8];
int* r1;
unsigned char* r2[512];
} B;

*/
用C#怎么写

指针的还不知道怎么表示,但是类型嵌套应是如下的样式:

struct b
{
public char mv;
public char n;
public b sp;
public int cn;
public int[] Seg=new int[8];
...
}

struct不是很好写,要用到Invoke的那种写法
简单的方法就是把struct当成class来写

[Red_angelX]

public int[] Seg=new int[8];
struct中不能有new 不能赋值

[cangwu_lee]

public int[8] Seg;

[Red_angelX]

public int[8] Seg;
一样报错 不能这么写
要用到那个[Mar..]什么的忘了

[Marshal]
我是建议把struct当成class来写 反正是一样的调用
指针麻..........,Marshal里好像也有

[axia_T]

嵌套不能用public b sp;
错误信息:causes a cycle in the struct layout

'这里有VB.NET的写法,可以用C#写出来吗

Public Const C1 As Short = 8
Public Const C2 As Short = 8

Structure A
Dim s As Integer
Dim d As Integer
<VBFixedArray(C1, 4)> Dim Sig(,) As Integer

Public Sub Initialize()
ReDim Sig(C1, 4)
End Sub
End Structure

Structure B
<VBFixedString(1), System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.ByValTStr, SizeConst:=1)> Public mv As String
<VBFixedString(1), System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.ByValTStr, SizeConst:=1)> Public n As String
Dim sb As B
Dim cn As Integer
<VBFixedArray(C2)> Dim Seg() As Integer

Public Sub Initialize()
ReDim Seg(C2)
End Sub
End Structure
