Convert comma separated string of ints to int array

Convert comma separated string of ints to int array

string sNumbers = "1,2,3,4,5";

If you want to throw an exception if a number couldn't be parsed, you can do it much more simply using LINQ:

(str ?? "").Split(',').Select<string, int>(int.Parse);

If you don't want to have the current error handling behaviour, it's really easy:

text.Split(',').Select(x => int.Parse(x));

return a list instead of int array:

var numbers = sNumbers.Split(',').Select(Int32.Parse).ToList();

List<int> numbers = new List<int>( Array.ConvertAll(sNumbers.Split(','), int.Parse) );

// Uses Linq

var numbers = Array.ConvertAll(sNumbers.Split(','), int.Parse).ToList();
