Co vraci metody DateTime ToString()

Pokud mate ve Windows/na serveru nastaveno zobrazeni data, casu, meny a cisel ala USA, vrati vam nize uvedene metody toto:
ToLongDateString(): Friday, July 27, 2012
ToLongTimeString(): 9:26:49 AM
ToShortDateString(): 7/27/2012
ToShortTimeString(): 9:26 AM
ToString(): 7/27/2012 9:26:49 AM

Pokud ceske / Ceska Republika, tak toto(je zde delsi posun casu, protoze jsem musel udelat reset PC):

ToLongDateString(): 27. cervence 2012
ToLongTimeString(): 9:46:17
ToShortDateString(): 27.7.2012
ToShortTimeString(): 9:46
ToString(): 27.7.2012 9:46:17

Datum muzete zobrazit metodou ToString() i jinak nez je nastaveno zobrazeni casu ve Windows. Konkretne takto(pokud nevite zkratku jazyku, podivejte se treba na http://sharpertutorials.com/list-of-culture-codes/ ):

dt.ToString(CultureInfo.GetCultureInfoByIetfLanguageTag("en-us"));

1	dt.ToString(CultureInfo.GetCultureInfoByIetfLanguageTag("en-us"));

Pokud chcete datum zobrazit v libovolnem formatu, neni treba to skladat nejak takto:

public static string UsaDateTimeToString(DateTime d)
{
    return d.Month + "/" + d.Day + "/" + d.Year + " " + d.Hour + ":" + d.Minute + ":" + d.Second;// +":" + miliseconds;     
}

public static string UsaDateTimeToString(DateTime d)

{

return d.Month + "/" + d.Day + "/" + d.Year + " " + d.Hour + ":" + d.Minute + ":" + d.Second;// +":" + miliseconds;

}

Jednoduse staci zavolat metodu takto:

dt.ToString("MM/dd/yyyy hh:mm:ss");

1	dt.ToString("MM/dd/yyyy hh:mm:ss");

Pokud zadate oba dva parametry metody ToString, “zvitezi” parametr string nad IFormatProvider:

dt.ToString("MM/dd/yyyy hh:mm:ss", CultureInfo.GetCultureInfoByIetfLanguageTag("cs-cz");

1	dt.ToString("MM/dd/yyyy hh:mm:ss", CultureInfo.GetCultureInfoByIetfLanguageTag("cs-cz");
