GetSystemInfo里的SYSTEM_INFO结构体在C#中如何表示？

[runerback]

C++：

typedef struct _SYSTEM_INFO {
  union {
    DWORD  dwOemId;
    struct {
      WORD wProcessorArchitecture;
      WORD wReserved;
    };
  };
  DWORD     dwPageSize;
  LPVOID    lpMinimumApplicationAddress;
  LPVOID    lpMaximumApplicationAddress;
  DWORD_PTR dwActiveProcessorMask;
  DWORD     dwNumberOfProcessors;
  DWORD     dwProcessorType;
  DWORD     dwAllocationGranularity;
  WORD      wProcessorLevel;
  WORD      wProcessorRevision;
} SYSTEM_INFO;

C#对应数据类型：
DWORD -> uint
DWORD_PTR -> UIntPtr
WORD -> ushort
LPVOID -> UInt32

主要是 union 不知道怎么写，看网上说的大概是：

    [StructLayout(LayoutKind.Explicit)]
    public struct SYSTEM_INFO
    {
        [FieldOffset(0)]
        uint dwOemId;

        [FieldOffset(0)]
        public struct _
        {
            public uint wProcessorArchitecture;
            public uint wReserved;
        }

        uint dwPageSize;
        UInt32 lpMinimumApplicationAddress;
        UInt32 lpMaximumApplicationAddress;
        UIntPtr dwActiveProcessorMask;
        uint dwNumberOfProcessors;
        uint dwProcessorType;
        uint dwAllocationGranularity;
        uint wProcessorLevel;
        ushort wProcessorRevision;
    }

照猫画虎写完，完全错了啊

或者教我个使用 GetSystemInfo 的办法也行，主要是获取 wProcessorArchitecture 这个值来判断具体的操作系统版本
