C# Regular Expression ends in _DXX where X is number

Question

I am trying to create a regular expression pattern in C# which allow you to have

next pattern: _DXX at the end of your .

Example :

04R5714A_D15 is correct

04R5714A_D05 is incorrect

04R5714A_D5 is correct

I tried : .*_D([1-9]{1}[0-9]?) but it didn't work :

Can you please put that in the question, and also try to make it more readable? I know not everybody knows perfect English,, but incomplete sentences + weird punctuation usually do not help in getting proper answers. — Peter B, Aug 14 '18 at 15:45
Why don't you clearly define the **rules** for what constitutes a valid pattern. Then it would be easier to define the pattern itself. — Kenneth K., Aug 14 '18 at 17:29

.*_D[1-9]\d?$ should work for you.

.* catches everything up until your underscore

_D is a literal match

[1-9] matches one number in that range

\d? matches 0 or 1 single number (0-9)

$ is the end of the string
