Answer 2

struct ATTGUARDCARD
{
int nFileSort;
int nCardID;
string strPersonID;
int nGrade, nAttGroup;
string  strUserKey;
string  strName;
datetime nYear, nMonth, nDay;
}
限定的长度再通过string.length 控制

struct ATTGUARDCARD
{
int nFileSort;

string strPersonID;
int nGrade, nAttGroup;
string strUserKey;
string strName;
int nYear, nMonth, nDay;
}

Answer 4

2楼的有问题，正确对应如下：  [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
  public struct MQTTC_Message
  {
     public int    nFileSort;
     public int    nCardID;
     [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 7)]
     public string strPersonID;
     public int    nGrade;
     public int    nAttGroup;
     [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 4)]
     public string strUserKey;
     [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 8)]
     public string strName;
     public int    nYear;
     public int    nMonth;
     public int    nDay;
   }
