如何将json对象反序列化为json字符串?

问题描述：

我有以下json:

{
  "name" : "tim",
  "items" : {
    "car" : "Mercedes",
    "house" : "2 Bedroom"
  }
}

要反序列化为的对象是:

The object to deserialize into is:

public class Person
{
    public string Name {get;set;}
    public string Items {get;set;}
}

我想将items反序列化为json对象的字符串.因此，本例中的Items应该是

I want to deserialize items into a string of the json object. So Items in this example should be

"{\"car\" : \"Mercedes\",\"house\" : \"2 Bedroom\"}"

我不在乎空格，例如制表符或换行符.如何使用Newtonsoft.Json做到这一点?我已尝试制作JsonConverter<string>，如此处所示，但reader.Value出现为null.

I don't care about spacing such as tabs or new lines. How can I do this using Newtonsoft.Json? I've tried making a JsonConverter<string> as shown here but reader.Value comes up as null.

我想避免反序列化items，然后再次将其序列化为字符串，因为我不知道items的形状，而且它可能也很大. >

I would like to avoid deserializing items and then serializing it into a string again as I do not know what shape items will be and it may also be large.

在获得其他答案的帮助并看了一些文档之后，我发现了

After some help from the other answers here and looking at the docs some more, I discovered the JObject.Load method. My converter works now, and looks like this:

public class StringConverter : JsonConverter<String>
{
    public override void WriteJson(JsonWriter writer, String value, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }

    public override Version ReadJson(JsonReader reader, Type objectType, Version existingValue, bool hasExistingValue, JsonSerializer serializer)
    {
        return JObject.Load(reader).ToString();
    }
}

现在我可以使用如下属性:

And I can now use the attribute like this:

public class Person
{
    public string Name {get;set;}

    [JsonConverter(typeof(StringConverter))]
    public string Items {get;set;}
}
