Answer 1

// first I need to create a match to see if the input string is in the corrent form
Match match = Regex.Match("image1-school", @"^image\d-(.*)$", RegexOptions.IgnoreCase);
// the parenthesis in the Regular Expression meeans the content must be place in a group
// as groups are 1 based, the first group is group[1]
if (match.Success)
{
     // this string will have the value of whatever was within the parenthesis
     string theStringYouWant = Regex.Match("image1-school", @"^image\d-(.*)$", RegexOptions.IgnoreCase).Groups[1].Value;
}
