.NET 4.5中的DateTime问题

Question

I'm trying to parse a DateTime in .NET 4.5. This is the code.

var rawDatetime = "10-11-2012, 11:19 AM";
var format = "MM-dd-yyyy, hh:mm tt";
var ok = DateTime.TryParseExact(rawDateTime, format, new CultureInfo("en-US"), DateTimeStyles.None, out dateTime);

This gives ok==false , and dateTime=010101 . What am I doing wrong? Does the framework have a bug?

Fixed with "DateTime.TryParseExact(rawDateTime, format, CultureInfo.InvariantCulture, DateTimeStyles.None, out dateTime);"

Answer 1

Are you sure this isn't the typo of rawDatetime vs rawDateTime (which are different variables and could have different values)?

It works fine for me:

var rawDateTime = "10-11-2012, 11:19 AM";
var format = "MM-dd-yyyy, hh:mm tt";
DateTime dateTime;
var ok = DateTime.TryParseExact(rawDateTime, format, new CultureInfo("en-US"),
    DateTimeStyles.None, out dateTime);
if (ok)
{   // following prints correctly
    Console.WriteLine(dateTime);
}
