Hello!!!
I couldn't understand your requirement clearly... however you can preserve your data using List
List<int> fieldindex1 = new List<int>();
for (int i = 0; i < 24; i++)
{
if (SID >= 10 && SID <= 11)
{
fieldindex1.Add(1);
timer1.Start();
}
if (SID >= 12 && SID <= 13)
{
fieldindex1.Add(2);
timer1.Start();
}
if (SI >= 14 && SID <= 15)
{
fieldindex1.Add(3);
timer1.Start();
}
}
