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.

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.
