Convert.DateTime

What Convert.DateTime will convert the date开发者_StackOverflow中文版 7/25/2010 12:00:00 it's current format is(MM/dd/yyyy HH:mm:ss)?

When I convert this string format to date time I am getting the error "string was not recognized as valid DateTime"

None. Dates are not stored internally as a certain format.

If you want to parse a string into a date, use DateTime.ParseExact or DateTime.TryParseExact (the former will throw an exception if the conversion fails, the second uses an out parameter):

DateTime myDate = DateTime.ParseExact("7/25/2010 12:00:00", 
                                      "MM/dd/yyyy HH:mm:ss",
                                      CultureInfo.InvariantCulture);

If you want to display a certain format, use ToString with the format string.

So, if you have a date object that represents midday of the 25th of July 2010 (doesn't matter how it is represented internally) and you want to format it with the format string "MM/dd/yyyy HH:mm:ss" you do the following:

string formattedDate = myDate.ToString("MM/dd/yyyy HH:mm:ss");

If you need to use Convert.DateTime, I'll assume you're working with a string you want to convert to a date. So you might try this:

DateTime date = Convert.DateTime("7/25/2010 12:00:00 am");
string formattedDateString = date.ToString("MM/dd/yyyy HH:mm:ss")

I'm making no assumptions as to why you'd want to do this, except that, well, you have your reasons.

DateTime.TryParse() or DateTime.Parse() will do the trick.

Edit: This is assuming that you are going from a string to a DateTime object.

Edit2: I just tested this with your input string, and I receive no error with DateTime.Parse
