Cast List<int> to List<string> in .NET 2.0
Can you cast a List<int> to List<string> somehow?
I know I could loop through and .ToString() the thing, but a cast would be awesome.
I'm in C# 2.0 (so no LINQ).
Solution 1:
.NET 2.0 has the ConvertAll method where you can pass in a converter function:
List<int> l1 = new List<int>(new int[] { 1, 2, 3 } );
List<string> l2 = l1.ConvertAll<string>(delegate(int i) { return i.ToString(); });
Solution 2:
Updated for 2010
List<int> l1 = new List<int>(new int[] { 1,2,3 } );
List<string> l2 = l1.ConvertAll<string>(x => x.ToString());
