示例

下面的示例创建一个新Form,并将附加到事件处理程序InputLanguageChanged事件。The following example creates a new Form and attaches an event handler to the InputLanguageChanged event. 此事件更改IMEmode当输入的语言更改为日语。This event changes the IMEmode when the input language changes to Japanese.

注解

创建 InputLanguageChangedEventHandler 委托时,需要标识将要处理该事件的方法。When you create an InputLanguageChangedEventHandler delegate, you identify the method that will handle the event. 若要将事件与事件处理程序关联,请将该委托的一个实例添加到事件中。To associate the event with your event handler, add an instance of the delegate to the event. 除非移除了该委托,否则每当发生该事件时就会调用事件处理程序。The event handler is called whenever the event occurs, unless you remove the delegate.

有关事件处理程序委托的详细信息,请参阅处理和引发事件For more information about event-handler delegates, see Handling and Raising Events.

扩展方法

GetMethodInfo(Delegate) GetMethodInfo(Delegate) GetMethodInfo(Delegate) GetMethodInfo(Delegate)

获取指示指定委托表示的方法的对象。Gets an object that represents the method represented by the specified delegate.
