I want to convert a string which contains the date in yyyyMMdd format to mm-dd-yyyy DateTime format. How do I get it?

Answer 1

CultureInfo provider = CultureInfo.CreateSpecificCulture("en-UK");   

string dateString = "19850121"; //in yyyyMMdd format 

string oldFormat = "yyyyMMdd"; 

DateTime result = DateTime.ParseExact(dateString, oldFormat, provider); //MM/dd/yyyyformat
