Json.NET反序列化对象始终显示null

代码如下：

Json.NET deserializing object returns null.

当我赋值时，它为空

{"recordsTotal":13,"recordsFiltered":13,"data":[{"Id":2,"Title":"Brajo testing","Type":null,"Description":null,"Importancy":null,"CreatedDate":"2017-03-16T14:31:04.41","Status":null,"Email":"+HNcbJGxLqAGmAQq9gOW1A==","Name":"Oliver Woodss"},{"Id":3,"Title":"udal testing","Type":null,"Description":null,"Importancy":null,"CreatedDate":"2017-03-16T14:31:41.253","Status":null,"Email":"+HNcbJGxLqAGmAQq9gOW1A==","Name":"Oliver Woodss"},

这样做,

result = this.Json(new { draw = draw, recordsFiltered = recordsTotal, recordsTotal = recordsTotal, data = _contacts }, JsonRequestBehavior.AllowGet);

var response=client.GetAsync（apirl）.Result；
var responseResult=JsonConvert.DeserializeObject
（response.Content.ReadAsStringAsync（）.Result）；
然后可以使用点运算符从responseResult获取数据。

哪个值会变为空？？您需要像这样分配recordsFiltered=_contacts.recordsTotal，_contacts.recordsTotal，…在_contacts中我得到的是null这里是modelpublic类用户{public User（）{UserList=new List（）；}public List UserList{get；set；}///////一个用户的用户名。例如：“sergiotapia，mrkibbles，matumbo”///[JsonProperty（“Id”）]公共字符串Id{get；set；}//////用户名。例如：“Sergio Tapia，John Cosack，Lucy McMillan”//[JsonProperty（“CreatedDate”）]公共日期时间CreatedDate{get；set；}响应结果错误无法反序列化当前JSON对象（例如，{“name”：“value”}）进入类型“System.Collections.Generic.List`1[EmailTemplate.UI.Areas.Ticket.Models.User]”，因为该类型需要JSON数组（例如[1,2,3]）才能正确反序列化。若要修复此错误，请将JSON更改为JSON数组（例如[1,2,3]），或更改反序列化类型，使其成为可以从JSON对象反序列化的正常.NET类型（例如，不是integer之类的基元类型，也不是数组或列表之类的集合类型）。还可以将JsonObjectAttribute添加到类型中，以强制它从第1行第16位的“recordsTotal”反序列化。我应该怎么做？使用此选项检查MODELCheck，List responseResult=（List）Newtonsoft.Json.JsonConvert.DeserializeObject（response），typeof（List）），是否有任何问题；如果Newtonsoft出现错误，则需要使用Nuget添加引用

{"recordsTotal":13,"recordsFiltered":13,"data":[{"Id":2,"Title":"Brajo testing","Type":null,"Description":null,"Importancy":null,"CreatedDate":"2017-03-16T14:31:04.41","Status":null,"Email":"+HNcbJGxLqAGmAQq9gOW1A==","Name":"Oliver Woodss"},{"Id":3,"Title":"udal testing","Type":null,"Description":null,"Importancy":null,"CreatedDate":"2017-03-16T14:31:41.253","Status":null,"Email":"+HNcbJGxLqAGmAQq9gOW1A==","Name":"Oliver Woodss"},

result = this.Json(new { draw = draw, recordsFiltered = recordsTotal, recordsTotal = recordsTotal, data = _contacts }, JsonRequestBehavior.AllowGet);

var response = client.GetAsync(apiUrl).Result;
var responseResult = JsonConvert.DeserializeObject<List<User>>
                    (response.Content.ReadAsStringAsync().Result);

Then you can fetch data from responseResult with a dot operator.
