Answer 1

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;
    }
}
