You can let DateTime structure parse the date (and cope with it in the best-try manner): try { string raw = 05/Jul/2011; DateTime dt = DateTime.Parse(raw); string formatted = dt.ToString(dd/MM/yyyy); Console.WriteLine(formatted); } catch (System.Exception ex) { Console.WriteLine(ex); } Make sure that all exceptions are handled because user is free to enter garbage in the text box. You can enforce input string to be in the format stated in your question by matching it against a regular expression: try { string raw = 05/Jul/2011; Regex reg = new Regex(@\d[\d]/(Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec)/\d\d[\d\d]); if (reg.IsMatch(raw)) { DateTime dt = DateTime.Parse(raw); string formatted = dt.ToString(dd/MM/yyyy); Console.WriteLine(formatted); } else { Console.WriteLine(Incorrect input string.); } } catch (System.Exception ex) { Console.WriteLine(ex); } In this code if you change string raw = 05/07/2011 that would print out Incorrect input string. without exception.

Use this function to convert the date. Note that if oldDate cannot be interpreted as a date an exception will be thrown. public string ConvertDate ( string oldDate) { return String . Format (  {0:dd/MM/yyyy}   DateTime . Parse (oldDate)); }
