Regular Expression for a SharePoint Correlation ID

  • Article

As someone who is horrible with regular expressions, it took me longer that it should have to figure out how to match an expression in the format of xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx where x is either a number from 0-9 or a letter from a-f. I hope this saves someone some time. There is probably a slicker way of doing this for those regex pros, but this works for me! Code is in C#, you will need the reference of 'using System.Text.RegularExpressions;' in your file.

 

bool match = Regex.IsMatch(valueYouAreComparing, @"([0-9a-f]{8})-([0-9a-f]{4})-([0-9a-f]{4})-([0-9a-f]{4})-([0-9a-f]{12})",RegexOptions.IgnoreCase);
