MVC4 WebApi序列化/反序列化MongoDB ObjectId [英] MVC4 WebApi Serialization/Deserialization MongoDB ObjectId

问题描述

我正在将MVC4 WebApi与RestSharp客户端一起使用，并且正在努力获取ObjectId以正确地序列化(或反序列化).

I am using MVC4 WebApi with a RestSharp client and I am struggling to get ObjectIds to serialize (or deserialize) properly.

我有一个像这样的基础课:

I have a basic class like so:

public class User
{

    [BsonId]
    public ObjectId Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }

}

在客户端上反序列化此对象的最佳/正确方法是什么?我尝试过的所有Id属性都具有ObjectId.Empty值.

What is the best/proper way to deserialize this object on the client? Everything I have tried the Id property is of value ObjectId.Empty.

我尝试创建一个不同的ObjectIdDeserializers.下面是反序列化器和客户端的示例，并将示例json发送回客户端.

I have tried a creating a different ObjectIdDeserializers. Below is an example of a deserializer and the client and sample json that is being sent back to the client.

public class ObjectIdDeserializer : IDeserializer
{

    public string RootElement { get; set; }
    public string Namespace { get; set; }
    public string DateFormat { get; set; }

    public T Deserialize<T>(RestSharp.IRestResponse response)
    {
        return BsonSerializer.Deserialize<T>(response.Content);
    }

}

在RestSharp中，我添加了以下行来调用上述反序列化器:

In RestSharp I have added the following line to call the above deserializer:

_client.AddHandler("application/json", new ObjectIdDeserializer());

一些示例json看起来像这样:

And some sample json looks like this:

"User":
{
    "Id":
    {
    "_timestamp":1339158960,
    "_machine":7962014,
    "_pid":4040,
    "_increment":9499872
    },
    "FirstName":"Test",
    "LastName":"User"
}

推荐答案

在SO上进行了大量搜索之后，我能够找到自己想做的简单解决方案.

After doing a bunch of searching on SO, I was able to find a simple solution for what I was trying to do.

使用此答案中的方法，该属性将存储为ObjectId，而在代码中它只是一个字符串.正是我希望达到的目标.

Using the approach in this answer, the property gets stored as an ObjectId and in code it is just a string. Exactly what I was hoping to achieve.
