Convert a string Date to the DateTime Format?

Question

I have very well researched all the question like this , this and this . However, no matter what I try I still get the Format exception:

string DatePaid="9/5/2012";
var date = DateTime.ParseExact(DatePaid, "dd/MM/yyyy", CultureInfo.InvariantCulture);

I have no idea what am I doing wrong?

Answer 1

EDIT:

Since you changed the date string your question to "9/5/2012" now it could be Day/Month/Year or Month/Day/Year , Assuming that it is Day/Month/Year , You are getting the exception because of using dd since that requires day part to be in double digits. So in your string the day 9 should be 09 .

You can use single d and M which would work for both single and double digit day and month part respectively.

So your code should be:

string DatePaid = "9/5/2012";
var date = DateTime.ParseExact(DatePaid, "d/M/yyyy", CultureInfo.InvariantCulture);

You are getting the format exception because your format is wrong. Your format should be "M/dd/yyyy" or if you have single digit day part then use d which would parse both single and double digit day part.

string DatePaid = "9/15/2012";
var date = DateTime.ParseExact(DatePaid, "M/d/yyyy", CultureInfo.InvariantCulture);

Answer 2

您的MM（月）等于15。一年中只有12个月而不是15个月。

Answer 3

Try like this.

      string DatePaid="9/15/2012";

 var date = DateTime.ParseExact(DatePaid, "M/dd/yyyy", CultureInfo.InvariantCulture);
