Question

I have to work with some files/folders which can contain certain prefixes. For example, a file name could be

1.2.0 MyDocfile.doc
1.1.2.3 Anotherfile.txt

I want to be able to remove the prefix and the space after that (1.2.0, 1.1.2.3) and just take the actual file name.
What is the best way to do this ? Regular expressions ?

Can someone please give an example?

Answer 1

var formattedName = name.Substring(name.IndexOf(" ") + 1);

In case of optional prefix you need regex:

var formattedName = Regex.Replace(name, @"^[\d.]* ",  "");

To get all file names formatted:

Regex regex = new Regex(@"^[\d.]* ");
IEnumerable<string> formattedNames = names.Select(f => regex.Replace(f, ""));
