以下代碼位於Windows Phone 8應用程序的app.xaml內。它收到錯誤The attachable property "ThemeDictionaries" was not found in type "ResourceDictionary"
。同樣,它不設置背景。我正在嘗試在整個應用程序中設置背景,並使用(App.Current.Resources["BackgroundImage"] as ImageBrush).ImageSource = imgSrc;
通過c#代碼進行更改。在「ResourceDictionary」類型中未找到可附加屬性「ThemeDictionaries」

謝謝,ThemeManager似乎破了。只需使用'ThemeManager.SetBackground(new Uri(「Assets/backgroundImage.jpg」,UriKind.Relative));'在新的全景頁面上調用時不執行任何操作並且不起作用。 – Euthyphro
確保您沒有在每個頁面中設置背景顏色 –
