MongoDB的C＃：ID序列化的最佳模式 [英] MongoDB C#: ID Serialization best pattern

问题描述

我有一个类用户，我需要在Web服务中与他们合作。

I have a class User and I need to work with them in web services.

那么问题是如果我尝试序列编号是 BsonObjectId 的类型，我看到
有一个空属性，这有一个空的财产，等等...

Then problem is that if I try to serialize Id that is type of BsonObjectId, I see that have an empty property, that have an empty property, and so on ...

我写这篇文章的解决方法，才能，这是是一个好的解决方案？

I have write this workaround in order, it's is a good solution?

public partial class i_User 
{
    [BsonId(IdGenerator = typeof(BsonObjectIdGenerator))]
    [NonSerialized]
    public BsonObjectId _id;

    public String Id
    {
        get
        {
            return this._id.ToString();
        }
    }   
}   

在这种方式，我可以保持 _id 为 BsonObjectId ，但我在属性发送在网上的字符串表示标识。

In this way, I can keep _Id as BsonObjectId but I send an string representation over the web in the property Id.

另一种方法是用 StringObjectIdGenerator

Another solution is to work with StringObjectIdGenerator

public partial class i_User 
{
    [BsonId(IdGenerator = typeof(StringObjectIdGenerator))]
    public String id;
}

不过是看到MongoDB的将存储字符串进入数据库，而不是的ObjectId 。

But is see that MongoDB will store a string into database instead of ObjectId.

什么是为了工作的最佳方法序列化环境如Web服务和/或客户端 - 服务器（Flash + C＃）？

What is the best approach in order to work in a serialization environmental like web services and/or an client-server (Flash+C#)?

推荐答案

如果我理解正确的话，您要访问的编号属性作为一个字符串，但有编号另存为的ObjectId 在MongoDB中。这可以通过使用 BsonRepresentation 与 BsonId 来完成。

If I understand you correctly, you want to access the Id property as a string, but have the Id saved as an ObjectId in MongoDB. This can be accomplished using BsonRepresentation with BsonId.

[BsonId]
[BsonRepresentation(BsonType.ObjectId)]
public string Id { get; set; }
