我有一个例外问题,找不到如何解决它的答案。 属性{staticresource spheacentbrush}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时,当我点击App_Info_Button时,System.Windows.apllication.loadComponent发生在App_info.g.i.cs中的例外时,上面的代码来自该文件。

以下是App_info.xaml上的内容面板定义

        <TextBlock Height="311" HorizontalAlignment="Center" Margin="25,32,0,0" Name="textBlock1" Text="This Application is designed ...." 
                   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,BindingFlags Invokeattr,BindingBinder,对象参数,CultureInfo文化,布尔斯基金德,汇编来电者,Boolean ReveryAccess,StackCrawlmark&Stackmark) 在system.reflection.runtimeConstructorInfo.internalInvoke(Object Obj,BindingFlags Invokeattr,Binder Binder,Object []参数,CultureInfo Culture,StackCrawlmark&Stackmark) 在System.Activator.InternalCreateInstance(类型类型,布尔非公开,StackCrawlmark&Stackmark) 在system.activator.createinstance(类型类型) 在system.windows.navigation.pageresourcecontloader.beginload_onuithread(asynccallback usercallback,pageresourceCecontLoaderAsyncresult结果) 在System.Windows.Navigation.PageresourceCecontopler。<> C_ DisplayClass4.B _0(对象args) 在system.reflection.runtimemethodinfo.internalinvoke(Runtimemethodinfo RTMI,Object OBJ,BindingFlags Invokeattr,Binder Binder,对象参数,CultureInfo Culture,Boolean IsbinderDefault,汇编来电,Boolean FirederAccess,StackCrawlmark&Stackmark) 在system.reflection.runtimemethodinfo.internalinvoke(Object Obj,BindingFlags Invokeattr,Binder Binder,Object []参数,CultureInfo Culture,StackCrawlmark&Stackmark) 在system.reflection.methodbase.invoke(对象obj,对象[]参数) 在system.delegate.dynamicInvokeone(对象[] args) 在system.multicastdelegate.dynamicinvokeimpl(对象[] args) 在system.delegate.dynamicInvoke(对象[] 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(对象[] args) 在system.windows.hosting.delegatewrapper.internalInvoke(对象[] args) 在System.Windows.Runtimehost.ManagedHost.Invokedelegate(Intptr Phandle,Int32 Nparamcount,ScriptParam [] PParams,ScriptParam&Presult)

有帮助吗?

解决方案

问题在于这一行:

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

您正在尝试将刷子资源值设置为样式,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}" />
.
