将视图模型添加到 视图 截获类型的类型映射

Question

我在WPF应用程序中一起使用Caliburn Micro和Ninject。我正在使用Ninject.Extensions.Interception来拦截和记录对我的 ViewModel 的调用，但这会阻止 Caliburn 找到 ViewModel 的视图，因为 Caliburn 正在被移交截获的视图模型（代理），该模型具有不同的命名空间和名称。

例如，而不是获得：

MyApp.ViewModels.OrdersViewModel

它正在得到：

Castle.Proxies.IOrdersProxy

更复杂的是，视图模型和视图位于不同的程序集中，因此不能假定命名空间。

由于我需要在运行时询问代理，因此我需要一种方法以编程方式挂钩到 View 解析，而不是通过添加字符串映射。我看不出有任何方法可以做到这一点 - 卡利本微型可以吗？

好的，我明白了。我没有与映射作斗争，而是在窗口管理器中解开代理：

using System;
using System.Collections.Generic;
using Caliburn.Micro;
using Castle.DynamicProxy;
namespace CAM.Utility
{
    public class WindowManagerEx : WindowManager, IWindowManagerEx
    {
        private readonly List<object> _trayIcons;
        public WindowManagerEx()
        {
            _trayIcons = new List<object>();
        }
        public override bool? ShowDialog(object rootModel, object context = null, IDictionary<string, object> settings = null)
        {
            rootModel = rootModel.UnwrapProxy();
            return base.ShowDialog(rootModel, context, settings);
        }
        public override void ShowWindow(object rootModel, object context = null, IDictionary<string, object> settings = null)
        {
            rootModel = rootModel.UnwrapProxy();
            base.ShowWindow(rootModel, context, settings);
        }
        public override void ShowPopup(object rootModel, object context = null, IDictionary<string, object> settings = null)
        {
            rootModel = rootModel.UnwrapProxy();
            base.ShowPopup(rootModel, context, settings);
        }
        public bool? ShowDialog<TViewModel>(object context = null, IDictionary<string, object> settings = null)
        {
            var viewModelInstance = IoC.Get<TViewModel>();
            return ShowDialog(viewModelInstance, context, settings);
        }
        public void ShowWindow<TViewModel>(object context = null, IDictionary<string, object> settings = null)
        {
            var viewModelInstance = IoC.Get<TViewModel>();
            ShowWindow(viewModelInstance, context, settings);
        }
        public void ShowPopup<TViewModel>(object context = null, IDictionary<string, object> settings = null)
        {
            var viewModelInstance = IoC.Get<TViewModel>();
            ShowPopup(viewModelInstance, context, settings);
        }
        public void ShowTrayIcon<TViewModel>(object context = null)
        {
            var viewModelInstance = IoC.Get<TViewModel>();
            _trayIcons.Add(viewModelInstance);
        }
        public void Dispose()
        {
            foreach (var trayIcon in _trayIcons)
            {
                var disposable = trayIcon as IDisposable;
                if (disposable != null)
                {
                    disposable.Dispose();
                }
            }
        }
    }
    public static class CastleProxyExtensions
    {
        public static object UnwrapProxy(this object target)
        {
            var proxy = target as IProxyTargetAccessor;
            if (proxy != null)
            {
                dynamic dynamicProxy = proxy;
                dynamic interceptors = dynamicProxy.__interceptors;
                dynamic interceptor = interceptors[0];
                target = interceptor.Instance;
            }
            return target;
        }
    }
}

另外，如果您想知道IWindowManagerEx是什么：

public interface IWindowManagerEx : IWindowManager, IDisposable
{
    bool? ShowDialog<TViewModel>(object context = null, IDictionary<string, object> settings = null);
    void ShowWindow<TViewModel>(object context = null, IDictionary<string, object> settings = null);
    void ShowPopup<TViewModel>(object context = null, IDictionary<string, object> settings = null);
    void ShowTrayIcon<TViewModel>(object context = null);
}
