var userVersionHTML = "2448hello2448welcome2448";
Regex regex = new Regex("2448(.*?)2448");
var v = regex.Match(userVersionHTML);
versionNumberStatus.Text = v.Groups[1].ToString();
usernameStatus.Text = v.Groups[2].ToString();
The goal is to get versionNumberStatus.Text
to display 'hello' and for usernameStatus.Text
to display 'welcome'.
The issue is that nothing appears for the usernameStatus.Text
. Any ideas?
You only have one capturing group here, in "2448(.*?)2448"
pattern so you cannot access .Groups[2]
.
A solution is to either split with 2448
or use the 2448(.*?)2448(.*?)2448
pattern.
See the regex demo .
Or this C# code:
var userVersionHTML = "2448hello2448welcome2448";
var chunks = userVersionHTML.Split(new[] {"2448"}, StringSplitOptions.RemoveEmptyEntries);
var versionNumberStatus = chunks[0];
var usernameStatus = chunks[1];
A solution is to use Matches()
with a regex like this:
var userVersionHTML = "2448hello2448welcome2448";
Regex regex = new Regex("(2448)?(.*?)2448");
var v = regex.Matches(userVersionHTML);
versionNumberStatus.Text = v[0].Groups[2].ToString();
usernameStatus.Text = v[1].Groups[2].ToString();
