Simple regex:

string s = "ABC142";    
var r= new Regex("^([A-Za-z]*)(\\d*)$");
var m = r.Match(s);
m.Groups[1].Index.Dump();  # index of the match
m.Groups[1].ToString().Dump();
m.Groups[2].Index.Dump(); # index of the match
m.Groups[2].ToString().Dump();

will print

0
ABC
3
142

(Dump is from LINQPAd, you can use Console.WriteLine etc).
