Question

我想根据展示广告或发生错误的情况更新我的用户界面。我正在使用AdRotator v2.1。查看源代码，如果无法从各种提供程序提供广告，则控件将崩溃，并且IsAdRotatorEnabled将设置为false。但该属性不会触发通知更改。如何检测是否没有展示广告？

Enabled="{Binding AreAdsEnabled,Mode=TwoWay,FallbackValue=true,UpdateSourceTrigger=PropertyChanged}"

这是我正在使用的黑客。它非常脆弱。它查看字符串的日志消息，以检测是否发生了错误。

public class BaseAdControl
{
    public AdRotatorControl CurrentAdRotatorControl { get; set; }
    private UserControl userControlWrapper;


    public BaseAdControl(AdRotatorControl MyAdRotatorControl, UserControl userControlWrapper)
    {
        // TODO: Complete member initialization
        this.CurrentAdRotatorControl = MyAdRotatorControl;
        this.userControlWrapper = userControlWrapper;


        MyAdRotatorControl.PlatformAdProviderComponents.Add(AdRotator.Model.AdType.PubCenter, typeof(Microsoft.Advertising.WinRT.UI.AdControl));
        MyAdRotatorControl.PlatformAdProviderComponents.Add(AdRotator.Model.AdType.AdDuplex, typeof(AdDuplex.Universal.Controls.Win.XAML.AdControl));


        MyAdRotatorControl.Loaded += MyAdRotatorControl_Loaded;
        MyAdRotatorControl.Unloaded += MyAdRotatorControl_Unloaded;
    }
