asp.net - How to convert date to mm/dd/yyyy format

Question

I want to convert dateformat to mm/dd/yyyy. Whatever dateformat is coming in textbox, I want to convert it into mm/dd/yyyy.

Answer 1

First you need to get it into a datetime object. The most common standards work via:

DateTime x = DateTime.Parse(txtDate.Text);

If you expect a freaky format, you still have to know what format it is:

DateTime x;
DateTime.TryParseExact(txtDate.Text, "YYddd", out x);

Then simply output the data:

string date = x.ToString("MM/dd/yyyy");

But you really need to enforce your formatting using regex, validators, scout's honor - something.
