Winforms Schleife funktioniert nicht

Hallo wir machen eine Anwendung für unsere Schule und wir brauchen das Formular zu aktualisieren (aktualisieren) alle 5 Sekunden. Wir haben versucht eine einfache "Do While" -Schleife und eine Zeitschleife, aber nichts scheint zu funktionieren, kann jemand helfen?Winforms Schleife funktioniert nicht

Der Code ist nicht sehr effizient, aber wir beginnen gerade Programmierer. der Teil, den wir loopen wollen, ist alles vom timer1_tick Teil bis zum Ende.

Wenn Sie Ihren Blick auf, wenn die Bedingungen Sie werden sehen, dass Sie das gleiche mehrmals überprüfen. Dies ist nicht erforderlich. Sie können alle Unterbedingungen in eine if-Klausel einfügen. –

Sie müssen den Timer starten:

timer1.Start();

Und Sie brauchen die Funktion InitializeTimer, vorzugsweise im Konstruktor aufzurufen

public Form1() 
{ 
    InitializeComponent(); 

    InitializeTimer(); 
}

Es tut mir leid, ich bin ziemlich neu beim Programmieren, könntest du mir sagen, wo genau ich das hinstellen sollte? –

@CrazeJocker Ich habe meine Antwort bearbeitet. Der Konstruktor wird aufgerufen, wenn das Formular erstellt wird. Auf diese Weise wird Ihr Timer initialisiert –
