which date you enter in textbox.. and what type of output you want.

What's an example of the content of tb_DateFrom.Text when you get the error ?

You have to handle incorrect user input, haven't you?

The date I entered was 21/12/2014

This is the error - String was not recognized as a valid DateTime.

I just tried that value against your code and it worked. Check that the string you enter is not being correpted somewhere.

I tried that code, with the date string you describe:

C#

string dateFromformat = "dd/MM/yyyy";
DateTime dateFrom1 = DateTime.ParseExact("21/12/2014", dateFromformat, CultureInfo.InvariantCulture);
DateTime dateFrom2 = DateTime.ParseExact("12/21/2014", dateFromformat, CultureInfo.InvariantCulture);

I get no error with the first conversion, but I do get a "Gregorian Calendar" exception when the second executes.

Did you perhaps miskey the input string?

(BTW: I'd use TryParseExact, instead of ParseExact, and report an error to the user instead of relying on the exception, or by preference use a DateTimePicker control instead of a TextBox - that way the user can't enter a wrong value and you get the DateTime directly without any conversions)
