Match value after semicolon without including comma

I need to match the string after the semicolon while not including the comma, i.e. I am specifically looking for the values 1, 2, 3, 4, 5, 6, etc.

Here is the input:

C07KTL89290003;1,C07KTL89290003,1;2,C07KTL89290003,0;3,C07KTL89290003,0;4,C07KTL89290003,0;5,C07KTL89290003,0;6,C07KTL89290003,0;7,C07KTL89290003,0;8,C07KTL89290003,0;9,C07KTL89290003,0;10,C07KTL89290003,0;11,C07KTL89290003,0;12,C07KTL89290003,0;13,C07KTL89290003,0;14,C07KTL89290003,0;15,C07KTL89290003,0;16,C07KTL89290003,0;17,C07KTL89290003,0;18,C07KTL89290003,0;19,C07KTL89290003,0;20,C07KTL89290003,0;21,C07KTL89290003,0;22,C07KTL89290003,0;23,C07KTL89290003,0;24,C07KTL89290003,0;25,C07KTL89290003,0;26,C07KTL89290003,0;27,C07KTL89290003,0;28,C07KTL89290003,0;29,C07KTL89290003,0;30,C07KTL89290003,0;31,C07KTL89290003,0;32,C07KTL89290003,0;33,C07KTL89290003,0;34,C07KTL89290003,0;35,C07KTL89290003,0;36,C07KTL89290003,0;37,C07KTL89290003,0;38,C07KTL89290003,0;39,C07KTL89290003,0;40,C07KTL89290003,0

The expression I am using right now is

\d+[,]+[^,]+[^,0-2]

However this is returning the number after a ;, a comma and the substring till the next comma.

Can someone please help me modify my expression to match only the digits after the semicolon while not including the comma?

In .NET, C# in your case, you may use 

(?<=;)\d+

Or, if you must specify that a valid match is only when a comma follows the digits:

(?<=;)\d+(?=,)

See the .NET regex demo and the regex graph:

enter image description here

Details

  • (?<=;) - a positive lookbehind that requires a ; to appear immediately to the left of the current location
  • \d+ - 1+ digits
  • (?=,) - (not really necessary here) a positive lookahead that requires a , to appear immediately to the right of the current location.

C# snippet:

var results = Regex.Matches(text, @"(?<=;)\d+")
        .Cast<Match>()
        .Select(x => x.Value);
