Facebook JSON字符串的反序列化？
我无法解决从运行我的fql查询后生成的JSON字符串中提取facebook用户的work_history，affiliations和current_loc的问题。
我做了这堂课：
public class Data { public CurrentLocation current_location { get; set; } public WorkHistory[] work_history { get; set; } public EducationHistory[] education_history { get; set; } } public class EducationHistory { public string name { get; set; } public int? year { get; set; } public string school_type { get; set; } } public class WorkHistory { public string company_name { get; set; } public Location location { get; set; } } public class CurrentLocation { public string city { get; set; } public string state { get; set; } public string country { get; set; } } public class Location { public string city { get; set; } public string state { get; set; } } 我的JSON字符串的格式是：
{"current_location":{"city":"Delhi","state":"Delhi","country":"India","zip":"","id":102161913158207,"name":"Delhi, India"} ,"education_history":[{"name":"IET , Alwar (Raj.)","year":2007,"concentrations":[],"school_type":"College"},{"name":"Institute of Engineering and Technology, Alwar","concentrations":[],"school_type":"College"}], "work_history": [{"location":{"city":"","state":""},"company_name":"Defence Research & Development Organisation (DRDO)","description":"","start_date":"0000-00","end_date":"0000-00"}]}
我如何提取此数据当我使用此代码时，我得到一个null：
Data soap = JsonConvert.DeserializeObject(ser);
编辑：我确实根据答案建议更改了代码我仍然没有得到任何值
编辑2：如果我只有一个用户，那么提供的解决方案会有效但是我有几个用户拥有这些详细信息我如何获得这些数据？ 对于不同的用户，有几个像下面给出的这些值

请帮忙
您需要使用与JSON结构匹配的正确属性名称：
using System; using Newtonsoft.Json; public class Data { public CurrentLocation current_location { get; set; } public WorkHistory[] work_history { get; set; } public EducationHistory[] education_history { get; set; } } public class EducationHistory { public string name { get; set; } public int? year { get; set; } public string school_type { get; set; } } public class WorkHistory { public string company_name { get; set; } public Location location { get; set; } } public class CurrentLocation { public string city { get; set; } public string state { get; set; } public string country { get; set; } } public class Location { public string city { get; set; } public string state { get; set; } } class Program { static void Main() { var json = @" { ""current_location"": { ""city"": ""Delhi"", ""state"": ""Delhi"", ""country"": ""India"", ""zip"": """", ""id"": 102161913158207, ""name"": ""Delhi, India"" }, ""education_history"": [ { ""name"": ""IET , Alwar (Raj.)"", ""year"": 2007, ""concentrations"": [], ""school_type"": ""College"" }, { ""name"": ""Institute of Engineering and Technology, Alwar"", ""concentrations"": [], ""school_type"": ""College"" } ], ""work_history"": [ { ""location"": { ""city"": """", ""state"": """" }, ""company_name"": ""Defence Research & Development Organisation (DRDO)"", ""description"": """", ""start_date"": ""0000-00"", ""end_date"": ""0000-00"" } ] }"; Data soap = JsonConvert.DeserializeObject(json); Console.WriteLine(soap.current_location.city); } }
关于affiliations属性，我没有看到与你的JSON有任何关系，所以我只是从Data对象中删除它并将其替换为EducationHistory类型。
更新：
要处理多个节点，您可以调整模型：
public class Result { public Data[] data { get; set; } } public class Data { public CurrentLocation current_location { get; set; } public WorkHistory[] work_history { get; set; } public EducationHistory[] education_history { get; set; } } public class EducationHistory { public string name { get; set; } public int? year { get; set; } public string school_type { get; set; } } public class WorkHistory { public string company_name { get; set; } public Location location { get; set; } } public class CurrentLocation { public string city { get; set; } public string state { get; set; } public string country { get; set; } } public class Location { public string city { get; set; } public string state { get; set; } }
然后：
Result soap = JsonConvert.DeserializeObject(json); Console.WriteLine(soap.data[0].current_location.city);
我没有宣布很多小class，而是采用dynamic方式。 这是动态json对象的代码。 用法将是这样的：
dynamic obj = JsonUtils.JsonObject.GetDynamicJsonObject(jsonString); Console.WriteLine("{0} , {1}", obj.current_location.city, obj.current_location.state); Console.WriteLine("EDUCATION"); foreach (var eduHist in obj.education_history) { Console.WriteLine("{0} , {1}", eduHist.name, eduHist.year); } Console.WriteLine("WORK"); foreach (var workHist in obj.work_history) { Console.WriteLine("{0} {1}-{2}", workHist.company_name, workHist.start_date, workHist.end_date); }
这是另一个用于检索id，姓名，图片和朋友的例子。 您必须包含对newtonsoft.json包的引用。
