asp.net – 相当于[DataMember(Name =“Test”)]的JsonResult

发布时间：2020-12-16 09:34:07 所属栏目：asp.Net 来源：网络整理

导读：我有一个方法这样做： public JsonResult Layar(string countryCode,string timestamp,string userId,string developerId,string layarName,double radius,double lat,double lon,double accuracy){ LayarModel model = new LayarModel(lat,lon,radius); ret

我有一个方法这样做：

public JsonResult Layar(string countryCode,string timestamp,string userId,string developerId,string layarName,double radius,double lat,double lon,double accuracy)
{
    LayarModel model = new LayarModel(lat,lon,radius);

    return Json(model,JsonRequestBehavior.AllowGet);
}

它返回此对象：

public class LayarModel
{        
    private List<HotSpot> _hotSpots = new List<HotSpot>();
    public List<HotSpot> HotSpots { get { return _hotSpots; } set { _hotSpots = value; } }    
    public string Name { get; set; }    
    public int ErrorCode { get; set; }
    public string ErrorString { get; set; }
}

我想要JSON

{"hotspots": [{
    "distance": 100,"attribution": "The Location of the Layar Office","title": "The Layar Office","lon": 4884339,"imageURL": http://custom.layar.nl/layarimage.jpeg,"line4": "1019DW Amsterdam","line3": "distance:%distance%","line2": "Rietlandpark 301","actions": [],"lat": 52374544,"type": 0,"id": "test_1"}],"layer": "snowy4","errorString": "ok","morePages": false,"errorCode": 0,"nextPageKey": null
}

一切都在返回的类中出现大写(HotSpots而不是热点).

我尝试过DataContract和DataMembers(Name =“Test”),但这不起作用.有什么建议？

解决方法

JsonResult()在内部使用JavaScriptSerializer进行序列化,似乎它不支持使用属性定义序列化属性名称.

DataContractJsonSerializer支持这一点,因此这可能是一种方法.
