I have a string like: string test = "1,2,3,4";

Is there any easier way (syntactically) to convert it to a List<int> equivalent to something like this:

string[] testsplit  = test.Split(',');
List<int> intTest = new List<int>();
foreach(string s in testsplit)
    intTest.Add(int.Parse(s));

Answer 1

You can throw LINQ at it:

List<int> intTest = test.Split(',').Select(int.Parse).ToList();

It first splits the string, then parses each part(returning an IEnumerable<int>) and finally constructs a list from the integer sequence.

Answer 2

var result = test.Split(',').Select(x => int.Parse(x));

Or, if you really want a List<int> (rather than just any IEnumerable<int>), append a .ToList().

Answer 3

test.Split(',').Select(x => int.Parse(x)).ToList()

Answer 4

Linq can make it a bit cleaner:

var intTest = test.Split(',').Select(s=>int.Parse(s)).ToList();
