动态过滤JSON信息

本文介绍了动态过滤JSON信息的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 您好， 我需要反序列化一些JSON，但问题是我的所有JSON对象都没有完全相同的格式。 以下是我必须反序列化的JSON示例： [ {" Player_Name"：" Zlatan Ibrahimovic"，" Country"：" Sweeden"，" Other_Informations"：{" Information1"：[ ] }，}， {" Player_Name"：" Pavel Nedved"，" Country"：" Czech Republic" " Personal_Honours"： {" Ballon_DOr" ;："One"，}，" Other_Informations" ;: {" Information1"：[ ] }，}， {" Player_Name"：" Zinedine Zidane"，" C ountry"：" Sweeden"，" Other_Informations"：{" Information1"：[ {" name"：" example"，} ] }，} ] 如您所见，某些字段仅针对某些对象显示，例如"Personal_Honours"。  我需要将JSON反序列化到这个类中：   public class PlayerData { public string Name {get;组; } public string BallonDor {get;组; } public string Information1 {get;组; } 公共字符串CurrentClub {get;组; } } 我使用的方法非常长并阻止了我的应用：  （在这个例子中，我使用Json来自文本文件，但通常 我必须发出REST请求..） StreamReader reader = File.OpenText（" TextFile1.txt"）; 列表< PlayerData> DataList控件; 动态值= JsonConvert .DeserializeObject< dynamic>（reader.ReadToEnd（））; DataList = new List< PlayerData>（）; foreach（动态数据价值） { if（data.Personal_Honours == null） { if（data.Other_Informations.Information1 = = null） { DataList.Add（new PlayerData { Name = data.Player_Name， Country = data.Country，}）; } else { DataList.Add（new PlayerData { Name = data.Player_Name， Country = data.Country， Information1 = data.Informations.Information1 }）; } } else { if（data.Other_Informations.Information1 == null） { DataList.Add（new PlayerData { Name = data.Player_Name， Country = data.Country， BallonDor = data.Personal_Honours.Ballon_DOr }）; } else { DataList.Add（new PlayerData { Name = data.Player_Name， Country = data.Country， BallonDor = data.Personal_Honours.Ballon_DOr， Information1 = data.Informations.Information1 }）; } } } 这种方法有效，但效率不高，阻止我的用户界面。  我该怎么做才能创建一个新的"PlayerData"  对象没有所有这些  '否则如果' 陈述？   谢谢！解决方案 首先你的JSON不正确并且要将新对象添加到列表中你必须只做  class 程序 { static void Main （ string [] args ） { List < 您的班级名称 > sampleList = new 列表 < your class name >（）; sampleList 。 添加 （ new 您的类名 （） { abc = " Main Street" ， xyz = " 1234" }）; } } public class " your class" { public string abc { get ; set ; } public string xyz { get ; set ; } } 如需进一步的帮助，请查看我的文章  http： //social.technet.microsoft.com/wiki/contents/articles/25648.learn-json-parsing-and-handling-live-data-in-10-mins.aspx Hello,I need to deserialize some JSON but the problem is that all of my JSON objects don't have the exact same format.Here is an example of the JSON that I have to deserialize :[ { "Player_Name": "Zlatan Ibrahimovic","Country": "Sweeden", "Other_Informations": { "Information1": [ ] }, }, { "Player_Name": "Pavel Nedved","Country": "Czech Republic","Personal_Honours": { "Ballon_DOr": "One", }, "Other_Informations": { "Information1": [ ] }, }, { "Player_Name": "Zinedine Zidane","Country": "Sweeden", "Other_Informations": { "Information1": [ { "name": "example", } ] }, } ]As you can see, some fields appear only for some objects for example "Personal_Honours". I need to deserialize the JSON into this class :   public class PlayerData{ public string Name { get; set; } public string BallonDor {get; set; } public string Information1{ get; set; } public string CurrentClub { get; set; }}I use this method which is really long and blocks my app : (In this exmple I use Json that comes frome a textfile but usually  I have to make a REST request..)StreamReader reader = File.OpenText("TextFile1.txt");List<PlayerData> DataList;dynamic value= JsonConvert .DeserializeObject<dynamic>(reader.ReadToEnd());DataList = new List<PlayerData>(); foreach (dynamic data in value) { if (data.Personal_Honours == null) { if (data.Other_Informations.Information1 == null) { DataList.Add(new PlayerData { Name = data.Player_Name, Country = data.Country, }); } else { DataList.Add(new PlayerData { Name = data.Player_Name, Country = data.Country, Information1 = data.Informations.Information1 }); } } else { if (data.Other_Informations.Information1 == null) { DataList.Add(new PlayerData { Name = data.Player_Name, Country = data.Country, BallonDor = data.Personal_Honours.Ballon_DOr }); } else { DataList.Add(new PlayerData { Name = data.Player_Name, Country = data.Country, BallonDor = data.Personal_Honours.Ballon_DOr, Information1 = data.Informations.Information1 }); } } }This method is working but it is not efficient and  blocks my UI. How can I do to create a  new "PlayerData"  object without having all of those   'else if'  statements ?  Thank you ! 解决方案 Firstly your JSON is not correct and to add new object to list you have to do just class Program{ static void Main(string[] args) { List<your class name> sampleList = new List<your class name>(); sampleList.Add(new your class name() { abc = "Main Street", xyz = "1234" }); }}public class "your class"{ public string abc{ get; set; } public string xyz{ get; set; }}For further help please have a look at my article http://social.technet.microsoft.com/wiki/contents/articles/25648.learn-json-parsing-and-handling-live-data-in-10-mins.aspx 这篇关于动态过滤JSON信息的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
