Question

Environment: Visual Studio 2008 SP1

What’s the regex to get that integer between parenthesis, 100 in this case?

string input = "bunch of text(100):   more text here ignore the 1 or 2 ints here";

Answer 1

That would be:

\d+

C# code (requires using System.Text.RegularExpressions, of course):

Regex re = new Regex(@"\d+");
string input = "bunch of text(100):   more text here";
Match m = re.Match(input);

if(m.Success) {
    // Your number is in m.Value
} else {
    // No number in the string
}
