Convert existing IEnumerable<int> to string (#,#,#,..) via Method

Question

I'm trying to convert an IEnumerable<int> to a string in the format #,#,#,... I'm having a terrible time attempting to make a method of this. What is a quick and easy way to handle?

Thanks.

Answer 1

Use String.Join:

string result = string.Join(",", enumerable);

Answer 2

Are you talking about something like:

string.Join(",", e.Select(i=>i.ToString()).ToArray());

i.e., concatenating an enumerable of ints (e in this case)?
