没有root对象的C＃数据契约 [英] C# data contract without root object

问题描述

我有这样的json输出，我找不到根对象。



[



{

Id：954，

FilmId：ST00000026，

标题：当前战争，

ScreenId：2，

PreShowStartTime：2018-01-25T11：00：00，

}，

{

Id：955，

FilmId：ST00000026，

标题：当前战争，

ScreenId：2，

PreShowStartTime：2018-01-25T13：10：00，

}

]



因此尝试通过DataContract将json转换为c＃使用此



[DataContract]



公共类RewardRequest1：JsonDataContractObject

{

[DataMember（Name = Id）]

public string Id {get;组; }



[DataMember（Name =FilmId）]

public string FilmId {get;组; }

}



它返回Null值，我找不到根对象。



我尝试了什么：



我试过arry但我无法获得列表。请帮我解决这个问题。

I have json output like this and i cannot find the root object.

[

{
"Id": 954,
"FilmId": "ST00000026",
"Title": "The Current War",
"ScreenId": 2,
"PreShowStartTime": "2018-01-25T11:00:00",
},
{
"Id": 955,
"FilmId": "ST00000026",
"Title": "The Current War",
"ScreenId": 2,
"PreShowStartTime": "2018-01-25T13:10:00",
}
]

So try to convert json to c# through DataContract using this

[DataContract]

public class RewardRequest1 : JsonDataContractObject
{
[DataMember(Name = "Id")]
public string Id { get; set; }

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

It returns Null value and i cannot find the root object.

What I have tried:

I tried arry but i cannot get the list. Please help me to fix this.

推荐答案

你的JSON没有根对象，你只需要创建一个包含2个对象的数组。



如果您要将JSON更改为

Your JSON has no root object, you've just create an array of 2 objects is all.

If you were to change your JSON to

{  
   "Items":[  
      {  
         "Id":954,
         "FilmId":"ST00000026",
         "Title":"The Current War",
         "ScreenId":2,
         "PreShowStartTime":"2018-01-25T11:00:00"
      },
      {  
         "Id":955,
         "FilmId":"ST00000026",
         "Title":"The Current War",
         "ScreenId":2,
         "PreShowStartTime":"2018-01-25T13:10:00"
      }
   ]
}

然后你的根对象将是Items，你的类结构看起来像

Then your root object would be "Items" and your class structure would look like

public class Item
{
    public int Id { get; set; }
    public string FilmId { get; set; }
    public string Title { get; set; }
    public int ScreenId { get; set; }
    public DateTime PreShowStartTime { get; set; }
}

public class RootObject
{
    public List<Item> Items { get; set; }
}

然后你可以使用json.net库做一些像
$ b $这样的事情b

Where you could then, using json.net library, do something like

var mydata = JsonConvert.DeserializeObject<RootObject>(myjsonstring>();

但是在你改变你提供的JSON之前，你没有根对象。

But until you alter your JSON that you've provided, you have no root object.
