【问题描述】：

我的 web 服务返回 json 数据，如下所示，但我想要的就像在 2nd CodeSnipts 中一样。我的网络服务和课程如下所示。

           "ShowID": 10107,
            "StartTime": "3:00 PM",
            "MovieID": 13,
            "Movie": "Bhaag Milkha Bhaag ",
            "Screen": "CDC SCreen2",
            "MediaPath": "bmb1_568962.jpg"
         ,  "ShowID": 115,
            "StartTime": "6:00 PM",
            "MovieID": 13,
            "Movie": "Bhaag Milkha Bhaag ",
            "Screen": "CDC SCreen2",
            "MediaPath": "bmb1_568962.jpg"
         ,  "ShowID": 110,
            "StartTime": "9:00 PM",
            "MovieID": 13,
            "Movie": "Bhaag Milkha Bhaag ",
            "Screen": "CDC SCreen2",
            "MediaPath": "bmb1_568962.jpg"
         

但我想像

   
        "MovieID": 13,
        "Movie": "Bhaag Milkha Bhaag ",
        "Screen": "CDC SCreen2",
        "MediaPath": "bmb1_568962.jpg",
        "ShowInfo": [
            
                "ShowID": 10107,
                "StartTime": "3:00 PM"
            ,
            
                "ShowID": 115,
                "StartTime": "6:00 PM"
            ,
            
                "ShowID": 110,
                "StartTime": "9:00 PM"
            
        ]
    

我的 Webservice 的 c# 代码

[WebMethod]
public string NowShowingGetList(DateTime ShowDate)

    HomeController obj = new HomeController();

    javascriptSerializer js = new JavaScriptSerializer();
    string retJSON = js.Serialize(obj.NowShowingGetList(ShowDate));
    return retJSON;

分类为

public class NowShowingInfo

    public int ShowID  get; set; 
    public string StartTime  get; set; 
    public int MovieID  get; set; 
    public string Movie  get; set; 
    public string Screen  get; set; 
    public string MediaPath  get; set; 

这里obj.NowShowingGetList(ShowDate)返回列表 提前谢谢你。

【问题讨论】：

你需要创建一个新的类名 ShowInfo 并在 NowShowingInfo 中添加它的 Array 或 List 。 ShowInfo 类将包含属性名称：ShowId 和 StartTime

你需要创建一个新的类名 ShowInfo 并在 NowShowingInfo 中添加它的 Array 或 List 。 ShowInfo 类将包含

【参考方案1】：

根据实体进行更改

public class NowShowingInfo

    public List<ShowInfo> ShowInformation  get; set; 
    public int MovieID  get; set; 
    public string Movie  get; set; 
    public string Screen  get; set; 
    public string MediaPath  get; set; 


public class ShowInfo

    public int ShowID  get; set; 
    public string StartTime  get; set; 

在您的网络服务中进行相关更改

【讨论】：

如何将我的 NowShowingInfo 转换为您的 NowShowingInfo obj.NowShowingGetList(ShowDate) 返回我的类型的 NowShowingInfo

新手意味着@NisargShah

好的。首先，您的 obj.NowShowingGetList(ShowDate) 现在将为 1 部电影返回 1 个值。 NowshowingInfo 的对象将只包含 1 部电影的一个值。并且演出时间将存储在列表中。 IE。 ShowInformation.Add(ShowInfoObject)

【参考方案2】：

信息如下

 public class ShowInfo
    
        public int ShowID  get; set; 
        public string StartTime  get; set; 
    
    public class NowShowing
    
        public List<ShowInfo> ShowInfo  get; set; 
        public int MovieID  get; set; 
        public string Movie  get; set; 
        public string Screen  get; set; 
        public string MediaPath  get; set; 
    

和

public List<NowShowing> NowShowingGetList(DateTime ShowDate)
                
        List<NowShowingInfo> objshowList = obj.NowShowingGetList(ShowDate);

        int movieID = 0;
        List<NowShowing> objShowingList = new List<NowShowing>();

        NowShowing obj2 = new NowShowing();
        ShowInfo objshowInfo = new ShowInfo();
        List<ShowInfo> objshowInfoList = new List<ShowInfo>();
        int count = 0;
        string Screen="";
        foreach (NowShowingInfo objs in objshowList)
        
            if (movieID != objs.MovieID )
            
                if (count != 0)
                
                    obj2.ShowInfo = objshowInfoList;
                    objshowInfoList = new List<ShowInfo>();
                    objShowingList.Add(obj2);
                    count = 0;
                
                obj2 = new NowShowing();
                obj2.MovieID = objs.MovieID;
                obj2.Movie = objs.Movie;
                obj2.Screen = objs.Screen;
                obj2.MediaPath = objs.MediaPath;

                if (count == 0)
                
                    objshowInfo = new ShowInfo();
                    objshowInfo.ShowID = objs.ShowID;
                    objshowInfo.StartTime = objs.StartTime;
                    objshowInfoList.Add(objshowInfo);
                

            
            else
            
                objshowInfo = new ShowInfo();
                objshowInfo.ShowID = objs.ShowID;
                objshowInfo.StartTime = objs.StartTime;
                objshowInfoList.Add(objshowInfo);
            
            movieID = objs.MovieID;
            Screen = objs.Screen;
            count++;
        

        obj2.ShowInfo = objshowInfoList;
        objShowingList.Add(obj2);
        return objShowingList;
