That one is great for a SortedList with keys that are strings. You’d have to manage casting if you have a SortedList with anything but string keys.

Thanks Pete!

Last one, promise!

How about this in SortedListKeysToDelimList?

string[] sa = new string[sl.Keys.Count];
sl.Keys.CopyTo(sa, 0);
return string.Join(delim, sa);

Not a bad idea, but I’d still say use a StringBuilder since you might not know the size of your incoming SortedList.

How’s about different?

SortedList sl = new SortedList();
sl.Add(1, “hi”);
sl.Add(2, “there”);
sl.Add(3, “everyone”);

IList il = sl.GetKeyList();
string str = string.Empty;

for (int i = 0; i < il.Count; i++)
{
str += i == 0 ? il[i].ToString() : string.Format(“,{0}”, il[i].ToString());
}
