Regular expression in c# for input like (integer-anything)

Question

string strRegexclass = @"^([0-9]+)\-([a-zA-Z])$";

I want to make regular expression which accept input like this (1-class). Any integer value before dash(-) and then must have dash then anything after dash.

Maybe `^[0-9]+-[a-zA-Z]+$` will do. If you really mean anything, then `^[0-9]+-.*$` — Wiktor Stribiżew, Dec 25 '16 at 14:20

You can use the code like this:

string strRegexclass = @"^\d+-.*$";

Or you can use the next code

string strRegexclass = @"^\d+-\w*$";

if you want to allow only letters after the dash.

If you plan to only match a string that starts with 1 or more ASCII digits, then a hyphen, and then any 0+ chars use:

^[0-9]+-.*$

See the regex demo

Note that \d and [0-9] are not equal in .NET regex flavor.
