查找资源字典时发生 Windows Phone 错误

所以，我正在创建通用的Windows Phone应用程序。我正在尝试更改透视标题面板中单击项目的颜色。我使用以下语法在Windows Phone项目中添加了Styleing.axml文件：

            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>

在共享项目的 App.xaml 文件中，我正在尝试添加这段代码

<ResourceDictionary x:Key="Dictionary">
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Styling.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>

但是我收到错误"查找资源字典"Styleing.axml"时发生 en 错误。

查找资源字典时发生 Windows Phone 错误

您需要为通用应用程序引用这样的字典（假设字典在共享项目中）：

<ResourceDictionary Source="ms-appx:///MyUniversaldResourceDictionary.xaml"/>

我最近在博客上写了这个，如果你想更详细一点：在通用应用中访问资源

所以我放弃了这种方法，这就是我在代码中解决它的方式：在 .xaml 文件中，在 Pivot 标记中添加此属性：SelectionChanged="MyPivot_SelectionChanged"

比在代码中：

 private void MyPivot_SelectionChanged(object sender,    SelectionChangedEventArgs e)
        {
            foreach (PivotItem pivotItem in MyPivot.Items)
            {
                if (pivotItem == MyPivot.Items[MyPivot.SelectedIndex])
                {
                    //selected
                   ((TextBlock)pivotItem.Header).Foreground = new SolidColorBrush(Windows.UI.Color.FromArgb(255,31, 93, 184));
                }
                else
                {
                     // not selected
                    ((TextBlock)pivotItem.Header).Foreground = new SolidColorBrush(Windows.UI.Color.FromArgb(255,109, 162, 240 ));
                 }
             }
         }
