RegEx to match string with digits and characters

Question

I want to create a regex to match one or two digits, followed by the character "M", followed by two digits, and then matching anything else, but it doesn't quite work:

I have this regex pattern:

string astring = "3M90-75";
string sPattern = "^\\d{1}M\\d{2}}$";
if (System.Text.RegularExpressions.Regex.IsMatch(astring, sPattern))
{
     //It's a match.
}

What you posted *isn't* a match. `\\d{2}}$` means two digits to the end of the input — Panagiotis Kanavos, Feb 15 '22 at 16:50
To avoid escaping backslashes in a regex, you can precede the string with an `@`: [What's the @ in front of a string in C#?](https://stackoverflow.com/a/556142/1115360). — Andrew Morton, Feb 15 '22 at 17:06

Use ^\d{1,2}M\d{2}.*:

\d{1,2}M One or two digit before M
\d{2} Two digit after M
.* To include the rest of string
