Use the regular expression groups : on MSDN.

In C#, try this :

string pattern = @"(\d+)@abc\.com";
string input = "My address is 15464684@abc.com and you can send SMS to me";
Match match = Regex.Match(input, pattern);

// Get the first named group.
Group group1 = match.Groups[1];
Console.WriteLine("Group 1 value: {0}", group1.Success ? group1.Value : "Empty");
