C# Regex take name from string

Question

Im getting strings somethink like this

"????log L 07/13/2012 - 23:59:21: \"Baobi<1><STEAM_ID_PENDING><>\" connected, address \"72.539.185.197:27005\"\n\0"

I had this method but sometimes its very buggy

 if (Data.EndsWith("\"")) Data = Data.Substring(0, Data.Length - 1);
                int start = Data.IndexOf("\"");
                int end = Data.IndexOf("<");
                var val = Data.Substring(start + 1, end - 1 - start);
                return val;

Please provides some good regex to get Baobi from here

Your current solution looks perfectly right to me. Why do you want a regex? — Haozhun

Good point, @Gene. OP: If you show some examples of what strings aren't working with your current code, we can be sure to have the regex take care of that. — Tim S.

Can't you see anything else about the error, e.g. to determine if Data was null or if an exception was thrown from Substring or IndexOf? You might want to put a try/catch around it and throw or log a more descriptive message that includes the contents of the string. — Tim S.

AFAIK this should work:

return Regex.Match(Data, @"""(.+?)<").Groups[1].ToString();

If this is still buggy, please give examples of strings that are problematic, and the results (e.g. exception details or what string was actually returned).

Or similarly, return Regex.Match(Data, @"""(.+?)<").Groups[1].ToString();. That has the advantage of allowing for more characters there (such as numbers).
