A simple string.Contains will do the job:

bool contains = fileName.Contains(name);

It will check if the fileName contains name and will return true if so. Note that Contains will match case-sensitive. It has to match exactly. If you want to match case insensitive, a regular expression or this post might be helpful, which tells you to use the current culture to do an IndexOf.
