c# - Check if string ends with 4 numbers

Question

I'm trying to figure out the best way to determine if a string ends with exactly 4 numbers. The number range would be from 0000-9999.

eg. I have a string that could be either "MVI_2546" or something like "FILETEST".

I need to parse that string and essentially return a true or false value depending on whether it ends in exactly 4 numbers or not.

Regex.Match can be used to test a string against a regular expression. It returns a Match-object where the Success property shows if a match was made.

Regex.Match(yourString, @"\d{4}$").Success

Use this in your test to see if yourString ends in four digits.
