c# - 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).ToString("yyyy-MM-dd");

This works the only problem is that when I have a date such as this "20070205" I get back "2007-01-05". I don't know why this is happening, any help is appreciated.

Answer 1

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

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