Question

Is that possible in C# to obtain array from System.Collections.IList interface without using Generics?

EDIT: I need some approach for converting collection to array. My collection is assigned to IList. Is that possible to do that? I don’t know real implementation of my collection so I can’t do e.g. like this
int[] arr = (ArrayList)list.ToArray();

You can use the CopyTo method:

IList list = new List<string>(new[] { "one", "two", "three" });
string[] array = new string[list.Count];
list.CopyTo(array, 0);
