Question

I have the following strings:

string a = "1. testdata";
string b = "12. testdata xxx";

What I would like is to be able to extract the number into one string and the characters following the number into another. I tried using .IndexOf(“.”) and then remove, trim and
substrings. If possible I would like to find something simpler as I have this to do in a
lot of parts of my code.

Answer 1

Proposed solutions so far are not correct.
First, after Split(‘.’) or Split(“.”) you will have space in the beginning of second substring.
Second, if you have more than one dot – you’ll have to do something yet after the split.

More robust solution is below:

string a = "11. Test string. With dots.";
var res = a.Split(new[] {". "}, 2, StringSplitOptions.None);
string number = res[0];
string val = res[1];

Argument 2 specifies maximum number of strings to return. Thus when you have several dots – it will make a split only at the first.
