C# 使用Prism和Unity在不同模块中切换视图

我想从模块视图导航到模块视图。如何在模块之间实现导航

在我使用Prism框架的应用程序中，我有两个模块

• 模块a
• 模块B

我在引导程序中配置了两个模块，如下所示：

protected override void ConfigureModuleCatalog()
        {
            base.ConfigureModuleCatalog();

            ModuleCatalog moduleCatalog = (ModuleCatalog)this.ModuleCatalog;
            moduleCatalog.AddModule(typeof(ModuleA));
            moduleCatalog.AddModule(typeof(ModuleB));
        }

public class ModuleA : IModule
    {

        private readonly IRegionManager  regionManager;
        private readonly IUnityContainer container;

        public StaffModule(IUnityContainer container, IRegionManager regionManager)
        {
            this.container     = container;
            this.regionManager = regionManager;
        }

        public void Initialize()
        {
            this.regionManager.RegisterViewWithRegion("MainRegion", () => this.container.Resolve<StaffView>());
         }           
    }


public class AccountModule : IModule
    {
        private readonly IRegionManager  regionManager;
        private readonly IUnityContainer container;

        public AccountModule(IUnityContainer container, IRegionManager regionManager)
        {
            this.container     = container;
            this.regionManager = regionManager;
        }

        public void Initialize()
        {
             container.RegisterType<object, AccountView>("AccountView");
            ////this.regionManager.RegisterViewWithRegion("MainRegion", () => this.container.Resolve<AccountView>());
        }
    }

container.RegisterTypeForNavigation<AccountView>();

我在我的模块a和模块b中注册我的视图，如下所示：

protected override void ConfigureModuleCatalog()
        {
            base.ConfigureModuleCatalog();

            ModuleCatalog moduleCatalog = (ModuleCatalog)this.ModuleCatalog;
            moduleCatalog.AddModule(typeof(ModuleA));
            moduleCatalog.AddModule(typeof(ModuleB));
        }

public class ModuleA : IModule
    {

        private readonly IRegionManager  regionManager;
        private readonly IUnityContainer container;

        public StaffModule(IUnityContainer container, IRegionManager regionManager)
        {
            this.container     = container;
            this.regionManager = regionManager;
        }

        public void Initialize()
        {
            this.regionManager.RegisterViewWithRegion("MainRegion", () => this.container.Resolve<StaffView>());
         }           
    }


public class AccountModule : IModule
    {
        private readonly IRegionManager  regionManager;
        private readonly IUnityContainer container;

        public AccountModule(IUnityContainer container, IRegionManager regionManager)
        {
            this.container     = container;
            this.regionManager = regionManager;
        }

        public void Initialize()
        {
             container.RegisterType<object, AccountView>("AccountView");
            ////this.regionManager.RegisterViewWithRegion("MainRegion", () => this.container.Resolve<AccountView>());
        }
    }

container.RegisterTypeForNavigation<AccountView>();

公共类模块a:IModule
{
专用只读IRegionManager regionManager；
专用只读IUnityContainer容器；
公共StaffModule（IUnityContainer容器、IRegionManager区域管理器）
{
this.container=容器；
this.regionManager=regionManager；
}
公共无效初始化（）
{
this.regionManager.RegisterViewWithRegion（“MainRegion”，（）=>this.container.Resolve（））；
}           
}
公共类AccountModule:IModule
{
专用只读IRegionManager regionManager；
专用只读IUnityContainer容器；
公共帐户模块（IUnityContainer容器、IRegionManager区域管理器）
{
this.container=容器；
this.regionManager=regionManager；
}
公共无效初始化（）
{
container.RegisterType（“AccountView”）；
////this.regionManager.RegisterViewWithRegion（“MainRegion”，（）=>this.container.Resolve（））；
}
}

当我从模块a中的StaffView单击按钮时，我想导航到模块b中的AccountView。这是我的导航代码

private void LodeViewfromModule()
{
   IUnityContainer unityContainer = ServiceLocator.Current.GetInstance<IUnityContainer>();
   var regionManager=unityContainer.Resolve<IRegionManager>();
   var uri = new Uri("pack://application:,,,/PrismAuto.Account;component/AccountView.xaml", UriKind.RelativeOrAbsolute);
   regionManager.RequestNavigate("MainRegion", uri);
}

private void LodeViewfromModule（）
{
IUnityContainer unityContainer=ServiceLocator.Current.GetInstance（）；
var regionManager=unityContainer.Resolve（）；
var uri=新的uri（“pack://application:，，，/PrismAuto.Account；component/AccountView.xaml“，UriKind.RelativeOrAbsolute）；
RequestNavigate（“MainRegion”，uri）；
}

但它表明：

对象异常

请任何人帮助我解决此问题。

您正在使用以下方式注册导航视图：

container.RegisterType<object, AccountView>("AccountView");

此外，如果您使用的是Prism 6，则Prism.Unity命名空间中有一个扩展方法，用于注册视图以进行导航，如下所示：

protected override void ConfigureModuleCatalog()
        {
            base.ConfigureModuleCatalog();

            ModuleCatalog moduleCatalog = (ModuleCatalog)this.ModuleCatalog;
            moduleCatalog.AddModule(typeof(ModuleA));
            moduleCatalog.AddModule(typeof(ModuleB));
        }

public class ModuleA : IModule
    {

        private readonly IRegionManager  regionManager;
        private readonly IUnityContainer container;

        public StaffModule(IUnityContainer container, IRegionManager regionManager)
        {
            this.container     = container;
            this.regionManager = regionManager;
        }

        public void Initialize()
        {
            this.regionManager.RegisterViewWithRegion("MainRegion", () => this.container.Resolve<StaffView>());
         }           
    }


public class AccountModule : IModule
    {
        private readonly IRegionManager  regionManager;
        private readonly IUnityContainer container;

        public AccountModule(IUnityContainer container, IRegionManager regionManager)
        {
            this.container     = container;
            this.regionManager = regionManager;
        }

        public void Initialize()
        {
             container.RegisterType<object, AccountView>("AccountView");
            ////this.regionManager.RegisterViewWithRegion("MainRegion", () => this.container.Resolve<AccountView>());
        }
    }

container.RegisterTypeForNavigation<AccountView>();

container.RegisterTypeForNavigation（）；

container.RegisterTypeForNavigation（）；

您是否尝试导航到新Uri（“AccountView”，UriKind.Relative）？毕竟，您已经在该“名称”下注册了它。您是否尝试导航到

新Uri（“AccountView”，UriKind.Relative）

？毕竟你是用这个“名字”注册的。非常感谢你的回答。非常感谢你的回答。
