Date formatting yyyymmdd to yyyy-mm-dd

Question

I\'m trying to convert a date in yyyymmdd format to yyyy-mm-dd with the following code:

tdrDate = DateTime.ParseExact(dateString, \"yyyymmdd\", null).ToStrin         


        

Answer 1

tdrDate = DateTime.ParseExact(dateString, "yyyyMMdd", null).ToString("yyyy-MM-dd");

You need MM, not mm. mm is for minutes.

Answer 2

Disclaimer I know nothing about C#'s date formatting.

But I'm guessing the problem is that you used mm in the first format string, and MM in the second.

Answer 3

Here you're parsing the date to create a date object, formatting the date object to a string, and discarding the date object. That sounds like more work than simple string processing:

tdrDate = dateString.Substring(0,4) + '-' + 
    dateString.Substring(4,2) + '-' + 
    dateString.Substring(6,2);

Unless you need the validation that's performed by DateTime.ParseExact(), which will throw a System.FormatException if given an invalid date, I'd probably just use the string formatting approach.

Answer 4

"yyyymmdd" must be "yyyyMMdd".

mm is for minutes.

Answer 5

Try this :

tdrDate = DateTime.ParseExact(dateString, "yyyyMMdd", null).ToString("yyyy-MM-dd");

use MM instead mm, mm is for minute & MM is for Month that is why it is taking 01 (default value of MM).

Answer 6

try this: DateTime.ParseExact("20070205", "yyyyMMdd", null).ToString("yyyy-MM-dd")
