C# 结构指针

我想用c为board sdk编写包装器。sdk中的功能实现为：

void WINAPI GetSysInfo(TC_INI_TYPE *TmpIni);

该TC_INI_类型的结构如下所示：

typedef struct {
    WORD wCardNo;                        
    WORD wCardType;                 
    WORD wConnect;                      
    WORD wIRQ;                      
    char cbDir[LEN_FILEPATH];           
    WORD wAddress[MAX_CARD_NO];     
    WORD wMajorVer;                 
    WORD wMinorVer;                 
    WORD wChType[MAX_CHANNEL_NO];   
} TC_INI_TYPE;

如何为结构

TC\u INI\u TYPE

编写包装器

[System.Runtime.InteropServices.StructLayout(System.Runtime.InteropServices.LayoutKind.Sequential, Pack = 4)]
public struct TC_INI_TYPE
{
   public short wCardNo;
   public short wCardType;
   public short wConnect;
   public short wIRQ;
   [System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.ByValArray, SizeConst = 32)] // change 32 to LEN_FILEPATH
   public char[] cbDir;
   [System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.ByValArray, SizeConst = 32)] // change 32 to MAX_CARD_NO
   public short[] wAddress;
   public short wMajorVer;
   public short wMinorVer;
   [System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.ByValArray, SizeConst = 32)] // change 32 to MAX_CHANNEL_NO
   public short[] wChType;
}

您可能还希望根据需要更改包值

对于GetSysInfo，请执行以下操作：

[DllImport("")] 
private static extern void GetSysInfo([In,Out] ref TC_INI_TYPE tcIniType);

不过，对于64位系统上的对齐方式不太确定。我认为它是在8字节边界上对齐的。
