Question

I have a string

"transform(23, 45)"

from this string i have to extract 23 and 45, i did

var xy = "transform(23,45)".Substring("transform(23,45)".indexOf('(') + 1).TrimEnd(')');
var num = xy.Split(',');

I am using c#. Is there any better method to do this in c#?

Answer 1

Use a Regular Expression:

string sInput = "transform(23, 45)";
Match match = Regex.Match(sInput, @"(\d)+",
              RegexOptions.IgnoreCase);

if (match.Success)
{
    foreach (var sVal in match)
             // Do something with sVal
}
