ProtoBuf-Net:从父类继承object []类型的[ProtoMember] [英] ProtoBuf-Net: Inheriting [ProtoMember] of type object[] from a parent class

问题描述

object [] mList持有子集合想要的任何对象. 对于其余指定的更多对象集合，这应该是伪包装类.

The object[] mList holds whatever objects that the child collection wants it to. This is supposed to be a dummy wrapper class for the rest of the more specified collections of objects.

[ProtoInclude(98, typeof(Object1CollectionProto))]
[ProtoInclude(99, typeof(Object2CollectionProto))]
[ProtoInclude(100, typeof(Object3CollectionProto))] 
public class ObjectCollectionProto
{
  protected ObjectType mCollectionType;
  protected object[] mList;
  public ObjectCollectionProto(){}

  [ProtoMember(1), DefaultValue(ObjectType.Base)]
  public ObjectType CollectionType //enumeration for type
  {
     get { return mCollectionType; }
     set { mCollectionType = value;}
  }

  [ProtoMember(2)]
  public object[] List
  {
     get { return mList; }
     set { mList = value;}
  }
}

然后我们有一个上面的虚拟包装器的子类示例，该子类应该继承其所需类型的object [].

Then we have an example child class of the above dummy wrapper that is supposed to inherit the object[] of it's desired type.

 [ProtoContract]
public class Object1CollectionProto : ObjectCollectionProto
{
  public Object1CollectionProto()
  {
  }
}

我如何指定类层次结构，以便Object1CollectionProto继承一个object [] mList作为可序列化的Object1的列表?就我而言，Object1已经可以序列化了.只是不是它们的集合版本.

How do I go about specifying the class hierarchy so that Object1CollectionProto inherits a the object[] mList as a list of Object1's that can be serialized? Object1's can be serialized in my case already. Just not the collection version of them.

推荐答案

如何序列化数组? 这是解决问题的好方法，只需重新构建框架以适合这种序列化数组的方式即可.

How to serialize arrays? This is a good way to solve the problem, just remake the framework to fit this way of serializing arrays.

我还经过一些仔细的思考，提出了一种正确地序列化 array 的方法.就我而言，我从不实际上序列化了 PARENT 类，但是我只序列化了儿童.

Also with some careful thinking I made a way of serializing that array correctly. In my case I NEVER actually serialize the PARENT class, but rather I only serialize the CHILDREN.

我从父类数组中删除了ProtoMember属性，并在子类中设置了该数组，并在CHILDREN类中添加了特定类型.

I removed the ProtoMember attribute from the parent class array and set the array in the children, with a specific type into the CHILDREN classes.

public class BaseCollection{
  protected object[] mList;
  /*
   * this has a lot more properties/functions that declare how I prepare  
   * collections for serialization but are superfluous for the conversation, 
   * hence the reason for me wanting to know how to do this
  */
}

public class ChildCollection : BaseCollection{
  [ProtoMember(1)]
  public Child[] childCollection
  {
    get { return mList as Child[]; }
    set { mList = value; }
  }
}
