如何使用正则表达式拆分字符串

Question

how do i use regex to split a string such as Manga vol 1-515 into 2 different outputs i want Manga vol 1-5 as 1 output and 15 as another. i want to output them both into 2 separate text boxes the last 2 digits of the string will always be what i want to split. currently my solution is

string pricepat = "[1,3,4][5,9,0]";
string Price = BtnGlobal.Text.ToString();
string priceMatches = Regex.Split(Price, pricepat);                
Pricetxt.Text = priceMatches.ToString();

Answer 1

For this case you can split it without Regex caption groups, and check that your string have at least two chars

string input = "Manga vol 1-515";
string firstPart = input.Substring(0, input.Length - 2);
string lastTwo = input.Substring(input.Length - 2);

Answer 2

You can use Regex Match to get the last two characters

string input = "Manga vol 1-515";
var result = Regex.Match(input, @"(.{2})\s*$");

txtFirst.Text = input.Replace(result.ToString(), "");
txtSecond.Text = result.ToString();
