wpf - 如何在 XAML 中指定泛型类型参数

Question

我的 MVP - PRISM WPF 应用程序有一个 BaseView。现在出于某种原因，我们考虑将 _presenter 作为 BaseView 中的模板化字段。

之前我的 View xaml 表示为

<base:BaseView xamlns:base="clr address of the dll which had BaseView" >

</base:BaseView>

现在我已经更改了 BaseView至BaseView<TPresenter>,那么我该如何编写Xaml呢？

从 .NET 4 Framework 和 XAML 2009 开始您就可以做到这一点。请参阅Generics in XAML在 MSDN 上

例如:

<my:BusinessObject x:TypeArguments="x:String,x:Int32"/>

对于 .NET 3.5:

For XAML 2006 usage when specifically targeting WPF, x:Class must also be provided on the same element as x:TypeArguments, and that element must be the root element in a XAML document. The root element must map to a generic type with at least one type argument. An example is PageFunction.

Possible workarounds to support generic usages include defining a custom markup extension that can return generic types, or providing a wrapping class definition that derives from a generic type but flattens the generic constraint in its own class definition.
