int iNumber = 2;

>>Thank you. I wonder though if the syntax "x =>" is something new, after .NET 2.0; since I have never seen it (and I am still working in .NET 2.0). But the key, as others suggested, is learning to "Split" (pun intended).

bool isWithin = cstring.Split(',').Contains(iNumber.ToString());
Again, thank you very much. As I just mentioned to Gregory, I can't seem to see the Contains in my list of methods (in Intellisense).
