Question

typedef struct
  {
        long SeriaINo;  //流水号
        UCHAR ValidateTime[7];  //有效期
        UCHAR IdentityCard[19]; //身份证号码
        UCHAR ICCardNo[13];    //卡编号
        UCHAR Name[17];        //姓名
        UCHAR gender;        //性别
  }_Badic_Info;int MakeCard(HANDLE icdev,LPCSTR psddword,_Basic_Info & Basic_Info,
              ussigned long&CardSn)用C#该怎么写

Answer 1

[StructLayout(LayoutKind.Sequential)]
        public struct struct_Basic_Info
        {
            public const int vTime = 7;
            public const int idCard = 19;
            public const int icCard = 13;
            public const int name = 17;
            /// <summary>
            /// 流水号
            /// </summary>
            public int serialNo;
            /// <summary>
            /// 性别｛男=1,女=0｝
            /// </summary>
            public byte gender;
            /// <summary>
            /// 卡片有效期限　格式:YYMMDD
            /// </summary>
            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = vTime)]
            public string validateTime;
            /// <summary>
            /// 身份证号码
            /// </summary>
            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = idCard)]
            public string IdentityCard;
            /// <summary>
            /// IC卡号码
            /// </summary>
            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = icCard)]
            public string ICCardNo;
            /// <summary>
            /// 姓名
            /// </summary>
            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = name)]
            public string Name;
        };[DllImport("QuickDEVCard.dll",CharSet = CharSet.Auto)]
public static extern int MakeCard(int icdev,[MarshalAs(UnmanagedType.LPStr)]     string  userPassword,ref  struct_Basic_Info rec,ref uint cardSN);                       为什么成功调用了,但是struct_Basic_Info这里存的数据都是乱码啊

Answer 2

一个是unicode编码，一个是char型本地编码，需要转换。

Answer 3

[DllImport("QuickDEVCard.dll",CharSet = CharSet.Auto)]最后的 CharSet 改成  Unicode

Answer 4

还是不行啊.出现乱码?validateTime,IdentityCard,ICCardNo这三个出现乱码
