Cast List to List in .NET 2.0

Question

Can you cast a List to List somehow?

I know I could loop through and .ToString() the thing, but a cast would be aw

Answer 1

You wouldn't be able to directly cast it as no explicit or implicit cast exists from int to string, it would have to be a method involving .ToString() such as:-

foreach (int i in intList) stringList.Add(i.ToString());

Edit - or as others have pointed out rather brilliantly, use intList.ConvertAll(delegate(int i) { return i.ToString(); });, however clearly you still have to use .ToString() and it's a conversion rather than a cast.

Answer 2

Converting from int List to string List can be done in two adittional ways besides the usual ToString(). Choose the one that pleases you more.

var stringlist = intlist.Select(x=>""+x).ToList();

Or also:

var stringlist = intlist.Select(x=>$"{x}").ToList();

And finally the traditional:

var stringlist = intlist.Select(x=>x.ToString()).ToList();
