使用protobuf-net合并收集属性对象

尝试使用protobuf-net合并保存和恢复对象。我可以得到简单的对象来工作，但我无法将集合属性对象获取到合并。任何来自protobuf网专家的帮助表示赞赏。使用protobuf-net合并收集属性对象

working code: 

using System; 
using System.Collections.Generic; 
using System.IO; 
using System.Runtime.Serialization; 
using ProtoBuf; 
class Program 
{ 
    static void Main(string[] args) 
    { 
     ChildTest(); 
     ParentTest(); 

     Console.Write("Press any key to continue..."); 
     Console.ReadKey(); 
    } 

    private static void ChildTest() 
    { 
     Console.WriteLine("ChildTest:"); 
     var child = new Child() {Name = "OriginalName"}; 

     var stream = new MemoryStream(); 
     Serializer.Serialize(stream, child); 
     var tempChild = Serializer.Deserialize<Child>(new MemoryStream(stream.ToArray())); 
     tempChild.Name = "MergedName"; 

     var stream1 = new MemoryStream(); 
     Serializer.Serialize(stream1, tempChild); 
     child = Serializer.Deserialize<Child>(new MemoryStream(stream1.ToArray())); 
     Console.WriteLine(child.Name + " - MergedName as expected"); 
    } 

    private static void ParentTest() 
    { 
     Console.WriteLine("ParentTest:"); 
     var child = new Child() {Name = "OriginalName"}; 
     var parent = new Parent {Items = new List<Child>(1)}; 
     parent.Items.Add(child); 

     var stream = new MemoryStream(); 
     Serializer.Serialize(stream,parent); 
     var tempParent = Serializer.Deserialize<Parent>(new MemoryStream(stream.ToArray())); 
     tempParent.Items[0].Name = "MergedName"; 

     var stream1 = new MemoryStream(); 
     Serializer.Serialize(stream1, tempParent); 
     parent = Serializer.Merge(new MemoryStream(stream1.ToArray()), parent); 
     Console.WriteLine(parent.Items[0].Name + " - MergedName expected here"); 

     Parent nullParent = null; 
     nullParent = Serializer.Merge(new MemoryStream(stream1.ToArray()), nullParent); 
     Console.WriteLine(nullParent.Items[0].Name+ " - MergedName as expected for null"); 
    } 
} 

[ProtoContract] //, ProtoInclude(2, typeof(Child[])) 
public partial class Parent : ISerializable 
{ 
    public Parent() { } 

    [ProtoMember(1)] 
    public List<Child> Items { get; set; } 

    protected Parent(SerializationInfo info, StreamingContext context) 
    { 
     Serializer.Merge<Parent>(info, this); 
    } 
    public void GetObjectData(SerializationInfo info, StreamingContext context) 
    { 
     Serializer.Serialize(info, this); 
    } 
} 

[ProtoContract] 
public partial class Child : ISerializable 
{ 
    public Child() { } 

    [ProtoMember(1)] 
    public string Name { get; set; } 

    protected Child(SerializationInfo info, StreamingContext context) 
    { 
     Serializer.Merge<Child>(info, this); 
    } 
    public void GetObjectData(SerializationInfo info, StreamingContext context) 
    { 
     Serializer.Serialize(info, this); 
    } 
}

显然这不能用protobuf网， - 有什么办法做我想做的事吗？即覆盖重复的属性？另一个图书馆呢？

这是预期的功能;合并一个单数属性确实会用合并流中的值覆盖属性;然而，对于重复的属性（列表，数组等），行为（按照更广泛的“protobuf”系列实现）是将来自合并流的附加对象附加到列表。

你会发现：

Console.WriteLine(parent.Items[0].Name); // prints OriginalName 
    Console.WriteLine(parent.Items[1].Name) // prints MergedName

具体而言，它不做一个项目，通过项目的位置合并。

谢谢马克，我希望能直接从你那里得到答案。有没有办法做我想做的事情？即覆盖重复的属性。 – 2011-03-28 12:32:56
