WPF ViewModel与多个View绑定后如何解决的问题

当重复创建View并绑定同一个ViewModel后，ViewModel中的字段更新，在新的View中的没有反应或者在View中找不到相应的视觉树（如ListBox的ListBoxItem)

初始的解决方案：View关闭后，注销属性Unregister Dependency。

如果可以将属性注销，貌似是可行的

注销属性 RemoveDependency(LoadCousewareItemAnimationProperty);

 1 private void RemoveDependency(DependencyProperty prop)
 2 {
 3   var registeredPropertyField = typeof(DependencyProperty).
 4     GetField("RegisteredPropertyList", BindingFlags.NonPublic | BindingFlags.Static);
 5   object list = registeredPropertyField.GetValue(null);
 6   var genericMeth = list.GetType().GetMethod("Remove");
 7   try
 8   {
 9     genericMeth.Invoke(list, new[] { prop });
10   }
11   catch (TargetInvocationException)
12   {
13     Console.WriteLine("Does not exist in list");
14   }
15 
16   var propertyFromNameField = typeof(DependencyProperty).
17     GetField("PropertyFromName", BindingFlags.NonPublic | BindingFlags.Static);
18   var propertyFromName = (Hashtable)propertyFromNameField.GetValue(null);
19 
20   object keyToRemove = null;
21   foreach (DictionaryEntry item in propertyFromName)
22   {
23     if (item.Value == prop){        
24        keyToRemove = item.Key;
25        return;
26     }
27   }
28   if (keyToRemove != null)
29   propertyFromName.Remove(keyToRemove);
30 }
