为什么我在UWP上看不到图标图像？

Question

我正在使用Xamarin.Forms，遵循此tutorial：

public MasterPage()
{
    var masterPageItems = new List<MasterPageItem>();
    masterPageItems.Add(new MasterPageItem
    {
        Title = "Contacts",
        IconSource = "contacts.png",
        TargetType = typeof(Pages.Contacts)
    });
    masterPageItems.Add(new MasterPageItem
    {
        Title = "ToDo",
        IconSource = "todo.png",
        TargetType = typeof(Pages.ToDo)
    });
    masterPageItems.Add(new MasterPageItem
    {
        Title = "Reminders",
        IconSource = "reminders.png",
        TargetType = typeof(Pages.Reminder)
    });
    masterPageItems.Add(new MasterPageItem
    {
        Title = "Login",
        IconSource = "reminders.png",
        TargetType = typeof(Pages.Login)
    });
    masterPageItems.Add(new MasterPageItem
    {
        Title = "Sign Up",
        IconSource = "reminders.png",
        TargetType = typeof(Pages.SignUp)
    });

    listView = new ListView
    {
        ItemsSource = masterPageItems,
        ItemTemplate = new DataTemplate(() => {
            var imageCell = new ImageCell();
            imageCell.SetBinding(TextCell.TextProperty, "Title");
            imageCell.SetBinding(ImageCell.ImageSourceProperty, "IconSource");
            return imageCell;
        }),
        VerticalOptions = LayoutOptions.FillAndExpand,
        SeparatorVisibility = SeparatorVisibility.None
    };

    Padding = new Thickness(0, 40, 0, 0);
    Icon = "hamburger.png";
    Title = "Personal Organiser";
    Content = new StackLayout
    {
        VerticalOptions = LayoutOptions.FillAndExpand,
        Children = {
        listView
    }
    };
}

我已将所有icons.png（待办事项，提醒等）放在MyProject.UWP根目录中。

但是当我从Visual Studio（调试模式，x64）运行它时，我无法在Master-Detail页面的导航布局中看到图标。

编辑：我无法在图片的属性中看到BuildAction字段：

编辑2：现在我明白了。您需要＆＃34;添加现有项目＆＃34;，而不是在文件夹上放置复制/粘贴图像。

Answer 1

BuildAction应设置为Content

Answer 2

我通过将所有图标添加到UWP的根项目并将构建操作属性设置为内容来解决此问题....
