EventHandler

範例

下列程式碼範例示範如何使用這個成員。The following code example demonstrates the use of this member. 在此範例中，事件處理常式會報告 RegionChanged 事件的發生。In the example, an event handler reports on the occurrence of the RegionChanged event. 此報表可協助您瞭解事件發生的時間，並可協助您進行調試。This report helps you to learn when the event occurs and can assist you in debugging. 若要報告多個事件或經常發生的事件，請考慮使用 Console.WriteLine 取代 MessageBox.Show，或將訊息附加到多行 TextBox。To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

若要執行範例程式碼，請將它貼入包含繼承自 Control之類型實例的專案，例如 Button 或 ComboBox。To run the example code, paste it into a project that contains an instance of a type that inherits from Control, such as a Button or ComboBox. 然後將實例命名為 Control1，並確定事件處理常式與 RegionChanged 事件相關聯。Then name the instance Control1 and ensure that the event handler is associated with the RegionChanged event.

private void Control1_RegionChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the Control.RegionChanged event.");
}

Private Sub Control1_RegionChanged(sender as Object, e as EventArgs) _ 
     Handles Control1.RegionChanged

   MessageBox.Show("You are in the Control.RegionChanged event.")

End Sub
