How to cast a LONG to a CString?

I want to cast a long to a cstring.

I've been struggling with this for a while and I've seen so many variants of solving this problem, more or less riddled with hassle and angst.

I know the question seems subjective, but it really shouldn't be in my opinion. There must be a way considered to be the best when the circumstances involve MFC and the standard libs that come with those circumstances.

I'm looking for a one-line solution that just works. Sort of like long.ToString() in C#.
