Question

Suppose you have a list<string[]>

  List<string[]> lst = new List<string[]>();

  lst.Add(new string[] { "A", "100.10" });
  lst.Add(new string[] { "B", "250.49" });

How do you get a sum of the second array items in the list?

Will need to convert the second array items to double and sum them up. Expected result is 350.59.

Thank you!

You could use:

double sum = lst.Sum(i => double.Parse(i[1]));
