我的代码如下所示:
引导程序
public class Bootstrapper : BootstrapperBase
{
private SimpleContainer _container = new SimpleContainer();
public Bootstrapper()
{
Initialize();
}
protected override void OnStartup(object sender, StartupEventArgs e)
{
base.OnStartup(sender, e);
DisplayRootViewFor<ShellViewModel>();
}
protected override void Configure()
{
_container.Singleton<IEventAggregator, EventAggregator>();
_container.Singleton<IWindowManager, WindowManager>();
_container.RegisterPerRequest(typeof(ShellViewModel), null, typeof(ShellViewModel));
}
protected override object GetInstance(Type service, string key)
{
return _container.GetInstance(service, key);
}
protected override IEnumerable<object> GetAllInstances(Type serviceType)
{
return _container.GetAllInstances(serviceType);
}
protected override void BuildUp(object instance)
{
_container.BuildUp(instance);
}
}
我的ShellViewModel样子是这样的:
ShellViewModel.cs
public class ShellViewModel : Conductor<Screen>
{
public ShellViewModel
{
var aViewModel = IoC.Get<AViewModel>();
ActivateItem(aViewModel);
}
}
但是每当我运行程序时,都会显示一个空白屏幕。当我调试它时,它说aViewModel是null.
有什么问题Bootstrapper吗?
