This matches an IP address, putting each number in its own group that can be retrieved by number. If you do not care about capturing the numbers, then you can make this shorter by putting everything after ^ until immediately after the first \. in a group ( ) with a {3} after it. Then put the number matching regex in once more. It only permits numbers in the range 0-255.

Just a simple regExp to parse the stack trace. Developed when using the exception block from MS, coz they only showed the stack all bunched together. Could be used as follows: [C#] string regExParams = @"(at\s)(?<fullClassName>.+)(\.)(?<methodName>[^\.]*)(\()(?<parameters>[^\)]*)(\))((\sin\s)(?<fileName>.+)(:line )(?<lineNumber>[\d]*))?"; Regex re = new System.Text.RegularExpressions.Regex(regExParams,RegexOptions.Compiled); MatchCollection mtc; mtc = re.Matches(System.Environment.StackTrace); foreach(Match mt in mtc) { MessageBox.Show(mt.Result("${fullClassName}")); MessageBox.Show(mt.Result("${methodName}")); MessageBox.Show(mt.Result("${parameters}")); MessageBox.Show(mt.Result("${fileName}")); MessageBox.Show(mt.Result("${lineNumber}")); } Seems to work well, but use at your own peril!! Feel free to use and enhance (there's probably a lot that could be done, like getting parameters individually(?), etc)
