5. Der Vergleich des 2 Objekte DateTime
// Wenn die Wert < 0 ist, d.h ist firstDateTime früher (vorn stehen)
// Wenn die Wert > 0 ist, d.h ist secondDateTime früher (vorne stehen).

Console.WriteLine("First DateTime: " + firstDateTime);
Console.WriteLine("Second DateTime: " + secondDateTime);
Console.WriteLine("Compare value: " + compare);// -1
if (compare < 0)
{
// firstDateTime ist früher als secondDateTime.
Console.WriteLine("firstDateTime is earlier than secondDateTime");
}
else
{
// firstDateTime ist später als secondDateTime
Console.WriteLine("firstDateTime is laster than secondDateTime");
}
Console.Read();
}
}
}
First DateTime: 9/2/2000 12:00:00 AM
Second DateTime: 1/20/2011 12:00:00 AM
Compare value: -1
firstDateTime is earlier than secondDateTime

out DateTime result)
Method | Example |
static DateTime Parse(string) | // See also Standard DateTime format. string httpHeaderTime = "Fri, 21 Feb 2011 03:11:31 GMT"; DateTime.Parse(httpHeaderTime); |
static DateTime ParseExact(
string s, string format, IFormatProvider provider ) | string dateString = "20160319 09:57";
DateTime.ParseExact(dateString ,"yyyyMMdd HH:mm",null); |
static bool TryParseExact(
string s, string format, IFormatProvider provider, DateTimeStyles style, out DateTime result ) | This method is very similar to ParseExact, but it returns a boolean, true if the time series is parsed, otherwise it returns false.
(See example below). |

DateTime dateTime = DateTime.ParseExact(dateString, "yyyyMMdd HH:mm", null);
Console.WriteLine("Input dateString: " + dateString);
Console.WriteLine("Parse Results: " + dateTime.ToString("dd-MM-yyyy HH:mm:ss"));
// Ein datetime String mit einem leeren Raum davon.
dateString = " 20110319 11:57";
// Die Methode TryParseExact benutzen.
// Die Methode gibt true zurück wenn das String 'dateString' analysiert werden können.
// Und die Wert für den Parameter 'out dateTime' zurückgeben.
bool successful = DateTime.TryParseExact(dateString, "yyyyMMdd HH:mm", null,
