Solution 2

Try this

C#

DateTime dateTo = DateTime.ParseExact(tb_DateTo.Text.Trim(), "MM/dd/yyyy", CultureInfo.InvariantCulture);
      string dateToFormat = dateTo.ToString("dd/MM/yyyy");

Solution 1

It's not necessarily wrong. I suspect you're getting a FormatException? When using ParseExact[^], the input string must exactly match the specified format, anything different and the parse will fail.

For example:

C#

DateTime.ParseExact("02/04/2014", "MM/dd/yyyy", CultureInfo.InvariantCulture)

Will parse just fine.

However, this:

C#

DateTime.ParseExact("02/04/2014 12:00:00", "MM/dd/yyyy", CultureInfo.InvariantCulture)

will fail

how do you check if date is empty in a textbox

Maarten Kools 4-Feb-14 3:55am

if (tb_DateTo.Text.Length != 0) // do something else

Member 10548723 4-Feb-14 4:13am

DateTime dateFrom = DateTime.ParseExact(tb_DateFrom.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture);
this still giving me string was not a valid datetime

Maarten Kools 4-Feb-14 4:15am

Then your input is incorrect. Like I said, if you use ParseExact, the input must exactly match the pattern. Any other case will give you a FormatException.

Ok, how you do a validation for this format dd/MM/yyyy
