我试图将我的Windows Phone 8 Silverlight应用程序转换为8.1 Phone应用程序,作为通用应用程序的一部分。我不知道这是否相关,因为这是我第一次试图正确实现视图模型。我想在Windows和Windows Phone视图之间共享数据。 无论如何,这是我得到的错误。MVVM Light“未在缓存中找到类型”
Error 3 Type not found in cache: ScoreAlerts.ViewModel.FixturesViewModel. C:\Users\Dave\Documents\Visual Studio 2012\Projects\Score Alerts\ScoreAlerts\ScoreAlerts.WindowsPhone\Pages\Fixtures.xaml 9 5 ScoreAlerts.WindowsPhone
Error 4 Type not found in cache: ScoreAlerts.ViewModel.HomePageViewModel. C:\Users\Dave\Documents\Visual Studio 2012\Projects\Score Alerts\ScoreAlerts\ScoreAlerts.Shared\Pages\HomePage.xaml 34 9 ScoreAlerts.WindowsPhone
这是我的视图模型定位器的外观
public class ViewModelLocator
{
/// <summary>
/// Initializes a new instance of the ViewModelLocator class.
/// </summary>
public ViewModelLocator()
{
if (!ViewModelBase.IsInDesignModeStatic)
{
ServiceLocator.SetLocatorProvider(() => SimpleIoc.Default);
if (ViewModelBase.IsInDesignModeStatic)
{
// Create design time view services and models
//SimpleIoc.Default.Register<IDataService, DesignDataService>();
}
else
{
// Create run time view services and models
//SimpleIoc.Default.Register<IDataService, DataService>();
}
SimpleIoc.Default.Register<HomePageViewModel>();
SimpleIoc.Default.Register<FixturesViewModel>();
}
}
[SuppressMessage("Microsoft.Performance",
"CA1822:MarkMembersAsStatic",
Justification = "This non-static member is needed for data binding purposes.")]
public HomePageViewModel Main
{
get
{
//return ServiceLocator.Current.GetInstance<HomePageViewModel>();
return SimpleIoc.Default.GetInstance<HomePageViewModel>("default");
}
}
[SuppressMessage("Microsoft.Performance",
"CA1822:MarkMembersAsStatic",
Justification = "This non-static member is needed for data binding purposes.")]
public FixturesViewModel Fixtures
{
get
{
//return ServiceLocator.Current.GetInstance<FixturesViewModel>();
return SimpleIoc.Default.GetInstance<FixturesViewModel>("default");
}
}
public static void Cleanup()
{
// TODO Clear the ViewModels
}
}
我的观点XAML有这个
DataContext="{Binding Fixtures, Source={StaticResource Locator}}"
和我的应用程序有这个
<viewModel:ViewModelLocator x:Key="Locator"
d:IsDataSource="True"/>
任何想法我做错了吗?
即使注册错误仍然存在。 –
同样在这里,但我有另外几十个其他ViewModel注册相同的方式。不明白为什么这个人会抛出这个错误。奇怪的是,它是一个空的,并且与其他的继承自同一个抽象类。困惑。还有其他建议吗? – Thierry
当你说在设计模式下没有执行一些代码时,你不是说你是如何修复它的?你可以解释吗? – Thierry
