I have a class which I need to save to a file. The class looks like this
class GLogInfo
{
public int tmno;
public int smno, seno;
public int vmode;
public int yr, mon, day, hr, min, sec;
public string photo { get { return (tmno == -1) ? "No Photo" : Convert.ToString(tmno); } }
public int enroll { get { return seno; } }
public int machine { get { return smno; } }
public string verify_mode
{
get
{
string attend_status = "";
switch ((vmode >> 8) & 0xFF)
{
case 0: attend_status = "_DutyOn"; break;
case 1: attend_status = "_DutyOff"; break;
}
string antipass = "";
switch ((vmode >> 16) & 0xFFFF)
{
case 1: antipass = "(AP_In)"; break;
case 2: antipass = "(AP_Out)"; break;
}
int vm = vmode & 0xFF;
string str = "--";
switch (vm)
{
case 1: str = "Fp"; break;
case 7: str = "FP+Card+Pwd"; break;
}
if ((1 <= vm && vm <= 7) ||
(30 <= vm && vm <= 34) ||
(51 <= vm && vm <= 53) ||
(101 <= vm && vm <= 103) ||
(151 <= vm && vm <= 153))
{
str = str + attend_status;
}
str += antipass;
return str;
}
}
public string logtime { get { return string.Format("{0:D4}-{1:D2}-{2:D2} {3:D2}:{4:D2}:{5:D2}", yr, mon, day, hr, min, sec); } }
}
populating the class with data from a device(access control device) using a dll code
while (true)
{
GLogInfo gi = new GLogInfo();
vRet = sbxpc.SBXPCDLL.GetGeneralLogData(Program.gMachineNumber,
out gi.tmno,
out gi.seno,
out gi.smno,
out gi.vmode,
out gi.yr,
out gi.mon,
out gi.day,
out gi.hr,
out gi.min,
out gi.sec);
if (!vRet) break;
glogs_.Add(gi);
}
With this I can bind the data to DataGridView without any problem. But I need to also get all the data to a file. either txt or any format. I tried to use serialization which I couldn't since I'm not that expert in C#. I need help as to how to write/read the data to a file. Also I though maybe there is a way to read the data from DataGridView to file but I cant do that either :). I'm a leaner.
You could use Newtonsoft to serialize the class to a file.
If you have an instance of GLogInfo
object (myObj), the code would look like:
File.WriteAllText(@"c:\temp\somefile.json", JsonConvert.SerializeObject(myObj));
This would serialize all public properties in your class that have 'get' accessors.
If you wish to ignore some of the properties, you could add [JsonIgnore]
.
