C# 使用LINQ解析JSON

你好，我面临一个非常简单的问题，但它没有得到解决。这是我的课堂设计

public class Program
{
    public string ProgramName { get; set; }
    public string ProgramTime { get; set; }
    public string ProgramDetails { get; set; }
}

public class Listing
{
    public string ChannelName { get; set; }
    public string NowShowing { get; set; }
    public string NowShowingTime { get; set; }
    public string NowShowingDescription { get; set; }
    public string NowShowingPicture { get; set; }
    public List<Program> Programs { get; set; }
}

public class RootObject
{
    public string status { get; set; }
    public string about { get; set; }
    public List<Listing> listings { get; set; }
}

帮我解决我的蹩脚方法。我关心的是正确解析项目，以及如何将它们添加到嵌套列表“程序”。第二个更为关键

示例Json输入-

   {
      "listings": [
      {
          "ChannelName": "NTV BANGLA",
          "NowShowing": "Ei Shomoy (R)",
          "NowShowingTime": "12:10",
          "NowShowingDescription": "Ei Shomoy is a daily talk show ........",
          "Programs": [
          {
              "ProgramName": "Ainer Chokhe (R)",
              "ProgramTime": "13:00",
              "ProgramDetails": "Human Rights and law based program Ainer Chokhe,"
          },
          {
              "ProgramName": "Shonkhobash",
              "ProgramTime": "15:10",
              "ProgramDetails": "Drama serial Shonkhobash, script by Bipasha Hayat and"
          }
        ]
      },
      {
          "ChannelName": "CHANNEL i",
          "NowShowing": "Taroka Kothon (Live)",
          "NowShowingTime": "12:30",
          "NowShowingDescription": "City Cell Taroka Kothon Live is a talk show ",
          "Programs": [
          {
               "ProgramName": "Channel i Top News",
               "ProgramTime": "13:00",
               "ProgramDetails": "Mutual Trust Bank top news (Shirsho Shongbad)"
       },
       {
               "ProgramName": "Ebong Cinemar Gaan",
               "ProgramTime": "13:10",
               "ProgramDetails": "Ebong Cinemar Gaan, a musical show based on "
        }
 ]
         }
      ]
   }

EDIT1

var customers = JsonConvert.DeserializeObject<RootObject>(e.Result);
Listing ls = new Listing
{
       ChannelName = customers.listings.First().ChannelName,
       NowShowing=customers.listings.First().NowShowing,
       Programs=??
};

var customers=JsonConvert.DeserializeObject（e.Result）；
清单ls=新清单
{
ChannelName=customers.listings.First（）.ChannelName，
NowShowing=customers.listings.First（）.NowShowing，
程序=？？
};

使用DataContractJsonSerializer在windows phone中解析json字符串

MemoryStream memoryStream = new MemoryStream(Encoding.Unicode.GetBytes(e.Result));

DataContractJsonSerializer dataContractJsonSerializer = new DataContractJsonSerializer(typeof(List<RootObject>));
RootObject itemDataList = dataContractJsonSerializer.ReadObject(memoryStream) as RootObject;

ChannelName = itemDataList.listings.First().ChannelName;

MemoryStream MemoryStream=newmemoryStream（Encoding.Unicode.GetBytes（e.Result））；
DataContractJsonSerializer DataContractJsonSerializer=新的DataContractJsonSerializer（类型（列表））；
RootObject itemDataList=dataContractJsonSerializer.ReadObject（memoryStream）作为RootObject；
ChannelName=itemDataList.listings.First（）.ChannelName；

如果

e.Result

是带有JSON的字符串，请尝试以下操作

var jss = new JavaScriptSerializer();
var o = jss.Deserialize<RootObject>(e.Result);

var jss=new JavaScriptSerializer（）；
var o=jss.反序列化（e.Result）；

更新
也许你需要这样的东西

var customers = JsonConvert.DeserializeObject<RootObject>(e.Result);
Listing ls = new Listing
{
    ChannelName = customers.listings.First().ChannelName,
    NowShowing=customers.listings.First().NowShowing,
    Programs=customers.listings.First().Programs
};

var customers=JsonConvert.DeserializeObject（e.Result）；
清单ls=新清单
{
ChannelName=customers.listings.First（）.ChannelName，
NowShowing=customers.listings.First（）.NowShowing，
Programs=customers.listings.First（）.Programs
};

如果你想在现有的基础上，你可以尝试这样做

var customers = JsonConvert.DeserializeObject<RootObject>(e.Result);
Listing ls = new Listing
{
    ChannelName = customers.listings.First().ChannelName,
    NowShowing=customers.listings.First().NowShowing,
    Programs=customers.listings.First().Programs.Select(p=>new Program{
                                        ProgramName=p.ProgramName,
                                        ProgramTime=p.ProgramTime, 
                                        ProgramDetails = p.ProgramDetails
                                       }).ToList()
};

var customers = JsonConvert.DeserializeObject<RootObject>(e.Result);
Listing ls = new Listing
{
    ChannelName = customers.listings.First().ChannelName,
    NowShowing=customers.listings.First().NowShowing,
    Programs=Enumerable.Range(1,10).Select(p=>new Program{
                                        ProgramName="generated name",
                                        ProgramTime="generated time", 
                                        ProgramDetails = "generated details"
                                       }).ToList()
};

var customers=JsonConvert.DeserializeObject（e.Result）；
清单ls=新清单
{
ChannelName=customers.listings.First（）.ChannelName，
NowShowing=customers.listings.First（）.NowShowing，
Programs=customers.listings.First（）.Programs.Select（p=>newprogram{
ProgramName=p.ProgramName，
编程时间=p.ProgramTime，
ProgramDetails=p.ProgramDetails
})托利斯先生（）
};

或者，如果你不是随机的，你可以试试这样的东西

var customers = JsonConvert.DeserializeObject<RootObject>(e.Result);
Listing ls = new Listing
{
    ChannelName = customers.listings.First().ChannelName,
    NowShowing=customers.listings.First().NowShowing,
    Programs=customers.listings.First().Programs.Select(p=>new Program{
                                        ProgramName=p.ProgramName,
                                        ProgramTime=p.ProgramTime, 
                                        ProgramDetails = p.ProgramDetails
                                       }).ToList()
};

var customers = JsonConvert.DeserializeObject<RootObject>(e.Result);
Listing ls = new Listing
{
    ChannelName = customers.listings.First().ChannelName,
    NowShowing=customers.listings.First().NowShowing,
    Programs=Enumerable.Range(1,10).Select(p=>new Program{
                                        ProgramName="generated name",
                                        ProgramTime="generated time", 
                                        ProgramDetails = "generated details"
                                       }).ToList()
};

var customers=JsonConvert.DeserializeObject（e.Result）；
清单ls=新清单
{
ChannelName=customers.listings.First（）.ChannelName，
NowShowing=customers.listings.First（）.NowShowing，
程序=可枚举。范围（1,10）。选择（p=>newprogram{
ProgramName=“生成的名称”，
ProgramTime=“生成时间”，
ProgramDetails=“生成的详细信息”
})托利斯先生（）
};

您必须迭代嵌套数组来创建

程序。

您可以提供样本json进行输入吗？您的解析代码没有运行时错误吗？您可以为json输入提供样本预期输出吗？这是说Path中的非法字符不幸的是，itemdatalist仍然为空。我遗漏了什么吗？我在我的ans中进行了编辑。请检查并让我知道它是否作为JObject工作JObject json=JsonConvert.DeserializeObject（e.Result）；我从这里获取json数据。问题在于解析和迭代。很抱歉，我无法正确表达我自己，我手中有数据，我想将它们分配给正确的属性以供以后使用。我如何填充ChannelName、NowShowing和最重要的嵌套数组程序？我不太明白你的意思，在

o

中，您已反序列化了具有字段属性的对象，包括

列表

，

列表

，因此您可以简单地获取它并进行更改，您可以提供示例您具体的意思吗？我已经解决了问题的第一部分（我将在回答中详细说明）。请告诉我如何在“程序”中插入数据？我遇到了麻烦，因为它是一个列表，而不是像“ChannelName”或“nowshiving”这样的属性。这是一个正确的方法。但是我也需要“ProgramName”、“ProgramTime”、“ProgramDetails”中的值。有一些铸造问题。已引发IEnumerable到泛型转换错误。
