对齐结构 [英] Struct with alignment

问题描述

有一个像这样的结构

Hi have a struct like that

typedef struct ServerState{
  WORD  Zone;              
  DWORD Init:1;        
  DWORD Link:1;  
  DWORD Spares:30;    
  WORD  Sectors;              
}TDeaMapServerState;

如何声明具有DWORD Init之类的维的字段:1;

How can I declare field with dimension like DWORD Init:1;

推荐答案

这应该有效:

This should work:

using System.Runtime.InteropServices;

[StructLayout(LayoutKind.Sequential)]
public struct ServerState
{
    public ushort Zone;
    [MarshalAs(UnmanagedType.ByValArray, SizeConst = 1)]
    public uint[] Init;
    [MarshalAs(UnmanagedType.ByValArray, SizeConst = 1)]
    public uint[] Link;
    [MarshalAs(UnmanagedType.ByValArray, SizeConst = 30)]
    public uint[] Spares;
    public ushort Sectors;
}
