DateTime.ToString（）不能按预期工作

Question

In the screenshot DateTime.ToString() method is being called but the date is not getting formatted in expected format (as seen in Quick Watch widnow). Is something wrong ?

Answer 1

You are using / as separator in your ToString format. But your current culture seems to has - as date separator. That is why you see the difference. You can pass CultureInfo.InvariantCulture with ToString .

Like:

DateTimeObject.ToString("MM/dd/yyy HHmmss", CultureInfo.InvariantCulture)

Answer 2

DateTime.ToString replaces / with the current date separator and : with the current time separator. You're passing in the format yourself, and it does not match what's in the Region settings.

To use the Region settings, use ToShortDateString() and ToShortTimeString() .

Answer 3

You can use this:

   DateTime.now.ToString("yyyyMMddHHmmss");

or

   DateTime.now.ToString("mm-dd-yyyy");
