Question

我遇到异常问题，无法找到解决方法。属性{StaticResource PhoneAccentBrush}值超出范围。

System.Windows.Application.LoadComponent(this, new System.Uri("/PAK_phone_side;component/Views/About/App_info.xaml", System.UriKind.Relative));
        this.LayoutRoot = ((System.Windows.Controls.Grid)(this.FindName("LayoutRoot")));
        this.TitlePanel = ((System.Windows.Controls.StackPanel)(this.FindName("TitlePanel")));
        this.ApplicationTitle = ((System.Windows.Controls.TextBlock)(this.FindName("ApplicationTitle")));
        this.PageTitle = ((System.Windows.Controls.TextBlock)(this.FindName("PageTitle")));
        this.ContentPanel = ((System.Windows.Controls.Grid)(this.FindName("ContentPanel")));
        this.textBlock1 = ((System.Windows.Controls.TextBlock)(this.FindName("textBlock1")));

在Windows Phone中，当我点击App_info_Button按钮时，System.Windows.Apllication.LoadComponent上发生异常。在App_info.g.i.cs中，上面的代码来自该文件。

这是App_info.xaml上的内容面板定义

                   VerticalAlignment="Center" Width="425" Style="{StaticResource PhoneAccentBrush}" />
    </Grid>
</Grid>    
</phone:PhoneApplicationPage>

这是堆栈跟踪

在System.Windows.Application.LoadComponent（对象组件，Uri resourceLocator）在PAK_phone_side.App_info.InitializeComponent（）在PAK_phone_side.App_info..ctor（）在System.Reflection.RuntimeConstructorInfo.InternalInvoke（RuntimeConstructorInfo rtci，BindingFlags invokeAttr，Binder binder，Object parameters，CultureInfo culture，Boolean isBinderDefault，Assembly caller，Boolean verifyAccess，StackCrawlMark＆amp; stackMark） at System.Reflection.RuntimeConstructorInfo.InternalInvoke（Object obj，BindingFlags invokeAttr，Binder binder，Object [] parameters，CultureInfo culture，StackCrawlMark＆amp; stackMark）在System.Activator.InternalCreateInstance（Type type，Boolean nonPublic，StackCrawlMark＆amp; stackMark）在System.Activator.CreateInstance（类型类型）在System.Windows.Navigation.PageResourceContentLoader.BeginLoad_OnUIThread（AsyncCallback userCallback，PageResourceContentLoaderAsyncResult result）在System.Windows.Navigation.PageResourceContentLoader。＆lt;＆gt; c_ DisplayClass4.b _0（Object args）在System.Reflection.RuntimeMethodInfo.InternalInvoke（RuntimeMethodInfo rtmi，Object obj，BindingFlags invokeAttr，Binder binder，Object parameters，CultureInfo culture，Boolean isBinderDefault，Assembly caller，Boolean verifyAccess，StackCrawlMark＆amp; stackMark）在System.Reflection.RuntimeMethodInfo.InternalInvoke（Object obj，BindingFlags invokeAttr，Binder binder，Object []参数，CultureInfo文化，StackCrawlMark＆amp; stackMark）在System.Reflection.MethodBase.Invoke（Object obj，Object []参数）在System.Delegate.DynamicInvokeOne（Object [] args）在System.MulticastDelegate.DynamicInvokeImpl（Object [] args）在System.Delegate.DynamicInvoke（Object [] args）在System.Windows.Threading.DispatcherOperation.Invoke（）在System.Windows.Threading.Dispatcher.Dispatch（DispatcherPriority priority）在System.Windows.Threading.Dispatcher.OnInvoke（对象上下文）在System.Windows.Hosting.CallbackCookie.Invoke（Object [] args）在System.Windows.Hosting.DelegateWrapper.InternalInvoke（Object [] args）在System.Windows.RuntimeHost.ManagedHost.InvokeDelegate（IntPtr pHandle，Int32 nParamCount，ScriptParam [] pParams，ScriptParam＆amp; pResult）

问题出在这一行：

<TextBlock Height="311" HorizontalAlignment="Center" 
           Margin="25,32,0,0" Name="textBlock1" 
           Text="This Application is designed ...." 
           VerticalAlignment="Center" Width="425" 
           Style="{StaticResource PhoneAccentBrush}" />

您正在尝试将画笔资源值设置为样式，这是导致异常的原因。您可以尝试将XAML更改为：

<TextBlock Height="311" HorizontalAlignment="Center" 
           Margin="25,32,0,0" Name="textBlock1" 
           Text="This Application is designed ...." 
           VerticalAlignment="Center" Width="425" 
           Style="{StaticResource PhoneTextNormalStyle}"
           Foreground="{StaticResource PhoneAccentBrush}" />

XAML解析异常：属性{StaticResource PhoneAccentBrush}值超出范围
