如何创建 Xamarin.Forms 自定义渲染器,其中渲染器基础 class 使用泛型?

How to create a Xamarin.Forms custom renderer, where the renderer base class uses generics?

我有一个基地class,它看起来像下面

public class DialogSelectionItem<Tobject> : ViewCell

现在我想给它附加一个自定义渲染器:

[assembly: ExportRenderer(typeof(SomeApp.CustomRenderers.DialogSelectionItem<Tobject>), typeof(SomeApp.iOS.CustomRenderers.DialogSelectionItemRenderer))]
namespace SomeApp.iOS.CustomRenderers
{
    public class DialogSelectionItemRenderer : ViewCellRenderer
    {
        // some customizations
    }
}

问题是

The type or namespace name 'Tobject' could not be found (are you missing a using directive or an assembly reference?)

我可以改用 object,但是自定义渲染器永远不会被调用。

是否有获取正确类型或使用泛型的选项?我应该如何定义 ExportRenderer?

好的解决方案已发布here

基础class:

public class DialogSelectionItem : ViewCell
{
    // nothing
}

public class DialogSelectionItem<Tobject> : DialogSelectionItem
{
    // do something
}

视图渲染器:

[assembly: ExportRenderer(typeof(SomeApp.CustomRenderers.DialogSelectionItem), typeof(SomeApp.iOS.CustomRenderers.DialogSelectionItemRenderer))]
namespace SomeApp.iOS.CustomRenderers
{
    public class DialogSelectionItemRenderer : ViewCellRenderer
    {
        // some customizations
    }
}
