就地修改属性映射,但如果类型不匹配,则调用以前的映射。
public:
generic <typename TVirtualView, typename TViewHandler>
where TVirtualView : Microsoft::Maui::IElement where TViewHandler : Microsoft::Maui::IElementHandler[System::Runtime::CompilerServices::Extension]
static void ModifyMapping(Microsoft::Maui::IPropertyMapper<Microsoft::Maui::IElement ^, Microsoft::Maui::IElementHandler ^> ^ propertyMapper, System::String ^ key, Action<TViewHandler, TVirtualView, Action<Microsoft::Maui::IElementHandler ^, Microsoft::Maui::IElement ^> ^> ^ method);
public static void ModifyMapping<TVirtualView,TViewHandler> (this Microsoft.Maui.IPropertyMapper<Microsoft.Maui.IElement,Microsoft.Maui.IElementHandler> propertyMapper, string key, Action<TViewHandler,TVirtualView,Action<Microsoft.Maui.IElementHandler,Microsoft.Maui.IElement>?> method) where TVirtualView : Microsoft.Maui.IElement where TViewHandler : Microsoft.Maui.IElementHandler;

<Extension()>
Public Sub ModifyMapping(Of TVirtualView As IElement, TViewHandler As IElement) (propertyMapper As IPropertyMapper(Of IElement, IElementHandler), key As String, method As Action(Of TViewHandler, TVirtualView, Action(Of IElementHandler, IElement)))
类型参数
- TVirtualView
跨平台类型。
- TViewHandler
处理程序类型。
参数
- propertyMapper
- IPropertyMapper<IElement,IElementHandler>
要在其中更改映射的属性映射器。
- key
- String
属性的名称。
- method
- Action<TViewHandler,TVirtualView,Action<IElementHandler,IElement>>
更新属性时要调用的已修改方法。
