c# - 如何适配Device.OnPlataform来切换(Device.RuntimePlatform)？

Question

我需要“更新”以下代码:

namespace Pizzahouse.Pages
{
public class IndexPage : ContentPage
{
    public IndexPage()
    {
        Title = "Index";

        var telephone = new Button()
        {
            Text = "Call",
            WidthRequest = 50,
        };
        telephone.Clicked += (sender, e) => Device.OpenUri(new Uri("tel://123465789"));

        Content = new ContentView()
        {
            Content = new StackLayout()
            {
                Children = {
                    new Image
                    {
                        Aspect = Aspect.AspectFit,
                        Source = Device.OnPlatform(
                            ImageSource.FromFile("PizzaIcon.png"),
                            ImageSource.FromFile("PizzaIcon.png"),
                            null)
                    }, telephone
                }
             }
        };
    }
}
}

我需要插入图像，但 Xamarin.Forms 说 Device.OnPlataform() 方法已过时，它说我应该使用 switch(Device.RuntimePlatform)。

这段代码确实有效，那么您有什么建议呢？感谢您的建议。

Source = (Device.RuntimePlatform == Device.WinPhone) ? null : ImageSource.FromFile("PizzaIcon.png");
