问题描述

我的MVP-PRISM WPF应用程序具有BaseView.现在由于某种原因,我们考虑将_presenter作为BaseView中的Templated字段.

I have a BaseView for my MVP - PRISM WPF application. Now for some reason we thought to make the _presenter as a Templated field in the BaseView.

之前,我将xaml表示为

earlier i had the view xaml representation as

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

</base:BaseView>

现在,因为我已经将BaseView更改为BaseView<TPresenter>,,那么我该如何编写Xaml?

now since i have changed the BaseView to BaseView<TPresenter>, So how shall i write the Xaml then?

推荐答案

.NET 4 Framework和XAML 2009开始,您就可以这样做.请参阅MSDN XAML中的泛型

You can do it since .NET 4 Framework and XAML 2009.See Generics in XAML on MSDN

例如:

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

对于.NET 3.5:

For .NET 3.5:

支持通用用法的可能解决方法包括定义一个 自定义标记扩展,可以返回通用类型,或提供 包装类定义,该类定义派生自泛型类型,但 使通用约束在其自己的类定义中变平整.

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.
