I was collect data an array with 2 coloumn look like this
---------------
Order | Value
---------------
order1 | 45
order2 | 70
order1 | 85
order2 | 32
--------------
Using Linq (Where
for Conditional) and (Sum
for Aggregate Functions):
var sum = array.Where(x=> x.Order == "order1").Sum(x=> x.Value);
If you really meant a 2-D (Multidimentional) Array, then you can do this:
object[,] array =
{
{ "order1", 45 }, { "order2", 70 },
{ "order1", 85 }, { "order2", 32 }
};
decimal Sum = 0;
for(int i = 0; i < array.GetLength(0); i++)
{
if (array.GetValue(i, 0)?.ToString() == "order1")
{
decimal val;
if(decimal.TryParse(array.GetValue(i, 1)?.ToString(), out val))
Sum += val;
}
}
