Hier ist eine TimeOfDay-Klasse mit vollem Funktionsumfang.
Dies ist in einfachen Fällen übertrieben, aber wenn Sie wie ich erweiterte Funktionen benötigen, kann dies hilfreich sein.
Es kann die Eckfälle, einige grundlegende Berechnungen, Vergleiche, die Interaktion mit DateTime, das Parsen usw. behandeln.
Unten finden Sie den Quellcode für die TimeOfDay-Klasse. Sie können Anwendungsbeispiele sehen und erfahren Sie mehr hier :
Diese Klasse verwendet DateTime für die meisten internen Berechnungen und Vergleiche, damit wir das gesamte bereits in DateTime eingebettete Wissen nutzen können.
