c# - How To Add In List Array Using Loop I am Getting Error? -


hi getting 1 value in list array not adding rows in it.. how add rows in list array ?

for(int a=0;a<_dt.rows.count;a++) {          double pw =convert.todouble(_dt.rows[a]["power"]);     int vol =convert.toint32(_dt.rows[a]["voltage"]);     double pv = pw * vol;     list<double> res = new list<double>();     res.add(pv); }

hopes suggestions..

regards,

you adding result list inside loop, must declare bevor loop:

list<double> res = new list<double>();              for(int a=0;a<_dt.rows.count;a++) {     double pw =convert.todouble(_dt.rows[a]["power"]);                  int vol =convert.toint32(_dt.rows[a]["voltage"]);                  double pv = pw * vol;                  res.add(pv);          }
