Ad Alanı:

System.Windows.Forms

Bütünleştirilmiş Kod:

System.Windows.Forms.dll

Olayın son oluşumuna Tick göre tetiklenmeden önce Tick milisaniye cinsinden süreyi alır veya ayarlar.

public:
 property int Interval { int get(); void set(int value); };

public int Interval { get; set; }

member this.Interval : int with get, set

Public Property Interval As Integer

Int32

Olayın Int32 son oluşumuna Tick göre olay tetiklenmeden önce Tick milisaniye sayısını belirten. Değer birden az olamaz.

Örnekler

Aşağıdaki kod örneği, beş saniyede bir alarm ayarlayan basit bir aralık zamanlayıcı uygular. Alarm oluştuğunda, MessageBox alarmın kaç kez başlatıldığının sayısını görüntüler ve kullanıcıya zamanlayıcının çalışmaya devam edip etmeyeceğini sorar.
