C# 查找资源字典时发生windows phone错误

因此，我正在创建通用windows phone应用程序。我正在尝试更改pivot标题面板中单击项目的颜色。我已使用以下语法在windows phone项目中添加了style.axml文件：

<ResourceDictionary

        <Setter Property="Padding" Value="0"/>
        <Setter Property="Foreground" Value="{ThemeResource PhoneForegroundBrush}"/>

                                        </ObjectAnimationUsingKeyFrames>
                                    </Storyboard>

                                        </ObjectAnimationUsingKeyFrames>
                                    </Storyboard>
                                </VisualState>
                            </VisualStateGroup>

                                    </PivotHeaderPanel.RenderTransform>
                                </PivotHeaderPanel>
                                <ItemsPresenter x:Name="PivotItemPresenter">
                                    <ItemsPresenter.RenderTransform>

                                </ItemsPresenter>
                            </PivotPanel>
                        </ScrollViewer>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>

在共享项目的App.xaml文件中，我试图添加这段代码

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

但是我发现错误“En error occurrent when finding the resource dictionary”styleing.axml.

您需要为通用应用程序引用这样的字典（假设字典位于共享项目中）：

如果你想了解更多细节，我最近在博客上写过：

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

而不是在代码中：

 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 ));
                 }
             }
         }

您的style.xaml文件是否在根文件夹中？并尝试从ResourceDictionary标记中删除x:Key=“Dictionary”…这是项目的结构..当我尝试删除键时，它会说“每个字典必须具有和关联的键”“您是在创建通用应用程序还是仅创建WINDOWS PHONE 8.1应用程序？这个style.xaml ResourceDictionary在两个应用程序中都使用，或者仅在windows phone应用程序中使用？我正在制作通用应用程序（但目前我只使用手机版本）…它仅在windows phone应用程序中使用..您有什么想法吗？阅读此文，

 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 ));
                 }
             }
         }
