C# DateTime ToString("MM-dd-yyyy") returns funny day values

Question

I have the following code in the codebehind file of an ASP.Net page

txtStartDate.Text = DateTime.Today.ToString("MM-dd-yyyy");

Which I expect to return "09-11-2009". However, when I run the page on the development server, I see "09-00-2009" in the text box. I can't see any reason for this, so I'm clearly missing something. Anyone have a clue?

Answer 1

I can't think why it would show 00, but as a random suggestion you could try:

... = DateTime.Today.ToString("MM-dd-yyyy", CultureInfo.InvariantCulture);

Answer 2

That format string should work as expected. I'd check your textbox to make sure you don't have some sort of mask (AJAX MaskedEditExtender?) on it. If you did, and maybe had the mask incorrect, it could overwrite what you were putting in the textbox.

Answer 3

could you check Datetime,Now.ToString() ?

Answer 4

Try something like this:

DateTime.Today.ToString("MM-dd-yyyy", CultureInfo.CreateSpecificCulture("en-US"))
