How can I convert comma separated string into a List

Question

string tags = \"9,3,12,43,2\"

List TagIds = tags.Split(\',\');

This doesn\'t work cause the split method returns a string[]

Answer 1

You can use LINQ w/ int.Parse() to convert the string[] to an IEnumerable and then pass that result to the List constructor:

var tagIds = new List(tags.Split(',').Select(s => int.Parse(s)));
