Convert String to Date - C #

Question

How can I convert a string like "Monday, March 25, 2010 ..." to 25/03/10? Also, is this possible?

Answer 1

You can use it DateTime.ParseExact, but I think you need to remove "On" before trying to analyze it.

EDIT According to the format documentation, you probably won’t need to disable On. after.

var theDate = DateTime.ParseExact(theString, "On dddd ddth MMMM yyy",
                  CultureInfo.InvariantCulture);

Must do it.

Answer 2

. , 25-, 22- 23-. , .

string s = "On Monday 25th March 2010";
string pattern = @"^[^0-9]+(\d+)(\w\w)?";
string clean = Regex.Replace(s, pattern,@"$1");
string result = DateTime.ParseExact(clean,"dd MMMM yyyy",
      CultureInfo.InvariantCulture)
     .ToString("dd/MM/yy");

Answer 3

, DateTime.ParseExact - . , ():

@"On dddd dd\t\h MMMM yyyy..."

't' 'h' , ( "AM/PM" "" ).

, . , 25 2010 , ; :

"On Thursday 25th March 2010..."

, :

"dd/MM/yy"
