请大家看看我转换的对不对，c++开发人员说转换有错。



typedef struct _sockaddr_my

{

short sin_family; //地址家族,AF_xxx

u_short sin_port; //端口号

struct { u_char s_b1,s_b2,s_b3,s_b4; } S_un_b; //IP地址

char sin_zero[8];  

}sockaddr_my;

typedef struct NewDHCP_Info

{

char hostmac[20];

sockaddr_my ipchange; 

sockaddr_my submaskaddr;

sockaddr_my gatewayaddr;

sockaddr_my dnsaddr;

sockaddr_my dhcpaddr;

char domainame[128];

int Flag;

int messagetype;

unsigned char Devtype;

char strSN[256];

char strDescriptName[256];

char UserName[256];

char Password[256];

unsigned char cDhcpAble;

unsigned char sub_device_type;

}NEWDHCP_INFO;

typedef void (*fDeviceInfoCallBack)(NEWDHCP_INFO* dhcp_info);

ALKSDK_API int SetDeviceInfoCallBack(fDeviceInfoCallBack fun);



public struct sockaddr_my

  {

  public Int16 sin_family;

  public UInt16 sin_port;

  public class S_un_b

  {

  public UInt16 s_b1, s_b2, s_b3, s_b4;

  }

  [MarshalAsAttribute(UnmanagedType.ByValTStr, SizeConst = 8)]

  public string sin_zero;

  }



  [StructLayoutAttribute(LayoutKind.Sequential, CharSet = CharSet.Ansi)]

  public class NewDHCP_Info

  {

  [MarshalAsAttribute(UnmanagedType.ByValTStr, SizeConst = 32)]

  public string strhostmac;



  public sockaddr_my ipchange;

  public sockaddr_my submaskaddr;

  public sockaddr_my gatewayaddr;

  public sockaddr_my dnsaddr;

  public sockaddr_my dhcpaddr;



  [MarshalAsAttribute(UnmanagedType.ByValTStr, SizeConst = 128)]

  public string domainame;



  public int Flag;

  public int messagetype;

  public byte Devtype;

  [MarshalAsAttribute(UnmanagedType.ByValTStr, SizeConst = 32)]

  public string strSN;

  [MarshalAsAttribute(UnmanagedType.ByValTStr, SizeConst = 32)]

  public string strDescriptName;

  [MarshalAsAttribute(UnmanagedType.ByValTStr, SizeConst = 32)]

  public string strUserName;

  [MarshalAsAttribute(UnmanagedType.ByValTStr, SizeConst = 32)]

  public string strPassword;   

  public byte cDhcpAble;

  public byte sub_device_type;

  }

除了长度不对，还有其他问题吗？？？

我觉得像char strSN[256]这种是转换成byte数组把

我错了，应该是这种
[MarshalAsAttribute(UnmanagedType.ByValTStr, SizeConst = 32)]
public string strPassword; 长度改改就行了
