Search Between Two List (Normalized Both List)

Question

Is there a better robust way to rewrite this using linq or any other way.

 

private static int getPowerIndexGreaterThanTargetPower(double target)

{

for (int i = 0; i < _color.PowerList.Count(); i++)

{

for (int j = 0; j < _color.PowerList[i].Count(); j++)

{

if (_color.PowerList[i][j] > target)

{

return j;

}

}

}

return -1;

}
