我向我的某些对象添加了自定义属性，如下所示：

[JsonCustomRoot("status")]
public class StatusDTO 
{
    public int StatusId { get; set; }
    public string Name { get; set; }
    public DateTime Created { get; set; }
}

该属性非常简单：

public class JsonCustomRoot :Attribute
{
    public string rootName { get; set; }

    public JsonCustomRoot(string rootName)
    {
        this.rootName = rootName;
    }
}

序列化对象实例时，JSON.NET的默认输出是：

{"StatusId":70,"Name":"Closed","Created":"2012-12-12T11:50:56.6207193Z"}

现在的问题是： 如何使用自定义属性的值向JSON添加根节点，如下所示 ：

{status:{"StatusId":70,"Name":"Closed","Created":"2012-12-12T11:50:56.6207193Z"}}

我发现有几篇文章提到了IContractResolver接口，但是我不知道该怎么做。我的尝试包括这段未完成的代码：

protected override JsonObjectContract CreateObjectContract(Type objectType)
{
    JsonObjectContract contract = base.CreateObjectContract(objectType);

    var info = objectType.GetCustomAttributes()
                   .SingleOrDefault(t => (Type)t.TypeId==typeof(JsonCustomRoot));
    if (info != null)
    {
        var myAttribute = (JsonCustomRoot)info;
        // How can i add myAttribute.rootName to the root from here?
        // Maybe some other method should be overrided instead?
    }

    return contract;
}
