C# 使用Key Ref的Spring.NET合并字典

相关的：

我试图在Spring.NET配置中创建合并的父/子继承对象，如下所示：

<object name=".parent" abstract="true" type="Assembly.KeysAndValues, Assembly">
  <property name="TheDictionary">
    <dictionary key-type="Assembly.KeyType, Assembly" value-type="Assembly.ValueType, Assembly">
      <entry key-ref="Object1" value-ref="Value1" />
      <entry key-ref="Object2" value-ref="Value2" />
      <entry key-ref="Object3" value-ref="Value3" />
    </dictionary>
  </property>
</object>

<object name="child" parent=".parent">
  <property name="TheDictionary">
    <dictionary merge="true">
      <entry key-ref="Object2"><null/></entry>
    </dictionary>
  </property>
</object>

spring集合合并是否不支持key ref，或者这里正在进行其他操作？

在对spring.NET源代码进行一些调试之后，我为spring.NET Github项目创建了一个pull请求，因为我认为这是库中的一个bug。有了我的零钱，词典合并就成功了。有关问题的详细信息，请参阅拉动请求：

Object2是否在spring容器中定义为singleton？我曾尝试将其标记为singleton，但相同的错误仍然存在，不管key ref对象上是否有该属性。我还尝试在key ref对象类型上实现相等成员，并继续看到错误。
