Question

I’m not sure what is the best way to convert an IList<string> (IList does not implement the ToArray property) to an string[] array.

I cannot use Linq because I’m compiling with .NET 2.0. Any ideas will be wellcome.

Answer 1

Use ICollection<T>.CopyTo:

string[] strings = new string[list.Count];
list.CopyTo(strings, 0);

I’m not quite sure if I understand the no-LINQ restriction though? It sounds like you would use ToArray if IList<T> had it. But it turns out it does because IEnumerable<T>.ToArray is an extension method defined on IEnumerable<T> of which IList<T> implements. So why don’t you just use that?
