I am able to get date and time using:
DateTime now = DateTime.Now;
How can I get the current date and time separately in the DateTime forma
See, here you can get only date by passing a format string. You can get a different date format as per your requirement as given below for current date:
DateTime.Now.ToString("M/d/yyyy");
Result : "9/1/2015"
DateTime.Now.ToString("M-d-yyyy");
Result : "9-1-2015"
DateTime.Now.ToString("yyyy-MM-dd");
Result : "2015-09-01"
DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss");
Result : "2015-09-01 09:20:10"
For more details take a look at MSDN reference for Custom Date and Time Format Strings
