MVC3 JSON序列化：如何控制房地产的名字呢？ [英] MVC3 JSON Serialization: How to control the property names?

问题描述

我想序列化一个简单对象来JSON：

I want to serialize a simple object to JSON:

public class JsonTreeNode
{
    [DataMember(Name = "title")]
    public string Title { get; set; }

    [DataMember(Name = "isFolder")]
    public bool IsFolder { get; set; }

    [DataMember(Name = "key")]
    public string Key { get; set; }

    [DataMember(Name = "children")]
    public IEnumerable<JsonTreeNode> Children { get; set; }

    [DataMember(Name = "select")]
    public bool SelectedOnInit { get; set; }
}

但每当我做到这一点：

But whenever I do it:

return Json(tree, JsonRequestBehavior.AllowGet);

属性名称不作为 [数据成员] 部分中指定，而是类似直接在类如中定义的在 SelectOnInit 的情况下，它是不是选择，但 SelectOnInit

The property names are not as specified in the [DataMember] section, but similar to the ones defined directly in the class e.g. in the case of SelectOnInit it is not select but SelectOnInit.

我在做什么错了？

推荐答案

我用在这个问题中的答案提供的技术解决了这个问题：

I solved the problem by using the technique provided in the answer in this question:

<一个href=\"http://stackoverflow.com/questions/1302946/asp-net-mvc-controlling-serialization-with-jsonresult\">ASP.NET MVC：与JsonResult 属性名称的控制序列

下面是我做的类：

/// <summary>
/// Similiar to <see cref="JsonResult"/>, with
/// the exception that the <see cref="DataContract"/> attributes are
/// respected.
/// </summary>
/// <remarks>
/// Based on the excellent stackoverflow answer:
/// http://stackoverflow.com/a/263416/1039947
/// </remarks>
public class JsonDataContractActionResult : ActionResult
{
    /// <summary>
    /// Initializes a new instance of the class.
    /// </summary>
    /// <param name="data">Data to parse.</param>
    public JsonDataContractActionResult(Object data)
    {
        Data = data;
    }

    /// <summary>
    /// Gets or sets the data.
    /// </summary>
    public Object Data { get; private set; }

    /// <summary>
    /// Enables processing of the result of an action method by a 
    /// custom type that inherits from the ActionResult class. 
    /// </summary>
    /// <param name="context">The controller context.</param>
    public override void ExecuteResult(ControllerContext context)
    {
        if (context == null)
            throw new ArgumentNullException("context");

        var serializer = new DataContractJsonSerializer(Data.GetType());

        string output;
        using (var ms = new MemoryStream())
        {
            serializer.WriteObject(ms, Data);
            output = Encoding.UTF8.GetString(ms.ToArray());
        }

        context.HttpContext.Response.ContentType = "application/json";
        context.HttpContext.Response.Write(output);
    }
}

用法：

    public ActionResult TestFunction()
    {
        var testObject = new TestClass();
        return new JsonDataContractActionResult(testObject);
    }

我也不得不修改初始类：

I also had to modify the initial class:

// -- The DataContract property was added --
[DataContract]
public class JsonTreeNode
{
    [DataMember(Name = "title")]
    public string Title { get; set; }

    [DataMember(Name = "isFolder")]
    public bool IsFolder { get; set; }

    [DataMember(Name = "key")]
    public string Key { get; set; }

    [DataMember(Name = "children")]
    public IEnumerable<JsonTreeNode> Children { get; set; }

    [DataMember(Name = "select")]
    public bool SelectedOnInit { get; set; }
}
