InputLanguageChangedEventHandler 代理人

代表將處理 InputLanguageChanged 之 Form 事件的方法。
public delegate void InputLanguageChangedEventHandler(System::Object ^ sender, InputLanguageChangedEventArgs ^ e);C#
public delegate void InputLanguageChangedEventHandler(object sender, InputLanguageChangedEventArgs e);C#
public delegate void InputLanguageChangedEventHandler(object? sender, InputLanguageChangedEventArgs e);type InputLanguageChangedEventHandler = delegate of obj * InputLanguageChangedEventArgs -> unitPublic Delegate Sub InputLanguageChangedEventHandler(sender As Object, e As InputLanguageChangedEventArgs)- sender
- Object
事件的來源。
下列範例會建立新的 Form ，並將事件處理常式附加至 InputLanguageChanged 事件。 當輸入語言變更為日文時，此事件會變更 IMEmode 。

當您建立 InputLanguageChangedEventHandler 委派 (Delegate) 時，就可以識別即將處理此事件的方法。 若要使事件與您的事件處理常式產生關聯，請將委派的執行個體 (Instance) 加入至事件。 除非您移除委派，否則每當事件發生時就會呼叫事件處理常式。
如需事件處理常式委派的詳細資訊，請參閱 處理和引發事件。
