在C＃中parsingJSON
我试图parsing来自Google AJAX Search API的一些JSON数据。 我有这个url ，我想分解它，以便显示结果。 我目前编写了这个代码，但是我很遗憾接下来要做什么，虽然有很多简单的JSONstring的例子。
作为C＃和.NET的新手，我一直在努力为我的ASP.NET页面获得一个真正的文本输出，所以我被推荐给JSON.NET一个尝试。 任何人都可以指向正确的方向，只需简单地编写一些代码，从Google AJAX Search API获取JSON并将其打印到屏幕上？
编辑：全部修复！ 所有结果工作正常。 再次感谢你Dreas Grech！

我刚刚意识到你为什么没有收到结果…你的Deserialize方法中有一个缺失的行。 你忘了把结果分配给你的obj ：
public static T Deserialize<T>(string json) { using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json))) { DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T)); return (T)serializer.ReadObject(ms); } }
另外，仅供参考，这里是Serialize方法：
public static string Serialize<T>(T obj) { DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType()); using (MemoryStream ms = new MemoryStream()) { serializer.WriteObject(ms, obj); return Encoding.Default.GetString(ms.ToArray()); } }
编辑
如果你想使用Json.NET这里是相当于上面代码的Serialize / Deserialize方法..
反序列化：
JsonConvert.DeserializeObject<T>(string json);
连载：
JsonConvert.SerializeObject(object o);
这已经是Json.NET的一部分，所以你可以在JsonConvert类中调用它们。

现在，你得到一个StackOverflow的原因是因为你的Properties 。
拿这个例子来说吧：
[DataMember] public string unescapedUrl { get { return unescapedUrl; } // <= this line is causing a Stack Overflow set { this.unescapedUrl = value; } }
请注意，在getter ，您正在返回实际属性（即属性的getter正在调用自己，因此您正在创build一个无限recursion）。
属性（在2.0中）应该像这样定义：
string _unescapedUrl; // <= private field [DataMember] public string unescapedUrl { get { return _unescapedUrl; } set { _unescapedUrl = value; } }
你有一个私人领域，然后你返回该领域的价值在吸气剂，并设置该领域的价值设置。
顺便说一句，如果你使用3.5框架，你可以这样做，避免支持字段，让编译器照顾：
public string unescapedUrl { get; set;}
您的数据类不匹配JSON对象。 用这个代替：
[DataContract] public class GoogleSearchResults { [DataMember] public ResponseData responseData { get; set; } } [DataContract] public class ResponseData { [DataMember] public IEnumerable<Results> results { get; set; } } [DataContract] public class Results { [DataMember] public string unescapedUrl { get; set; } [DataMember] public string url { get; set; } [DataMember] public string visibleUrl { get; set; } [DataMember] public string cacheUrl { get; set; } [DataMember] public string title { get; set; } [DataMember] public string titleNoFormatting { get; set; } [DataMember] public string content { get; set; } }
此外，您不必实例化类以获取其反序列化types：
public static T Deserialise<T>(string json) { using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(json))) { var serialiser = new DataContractJsonSerializer(typeof(T)); return (T)serialiser.ReadObject(ms); } }
我发现这种将JSONparsing为dynamic对象的方法 ，它扩展了DynamicObject和JavascriptConverter以将string转换为对象。
DynamicJsonObject
public class DynamicJsonObject : DynamicObject { private IDictionary<string, object> Dictionary { get; set; } public DynamicJsonObject(IDictionary<string, object> dictionary) { this.Dictionary = dictionary; } public override bool TryGetMember(GetMemberBinder binder, out object result) { result = this.Dictionary[binder.Name]; if (result is IDictionary<string, object>) { result = new DynamicJsonObject(result as IDictionary<string, object>); } else if (result is ArrayList && (result as ArrayList) is IDictionary<string, object>) { result = new List<DynamicJsonObject>((result as ArrayList).ToArray().Select(x => new DynamicJsonObject(x as IDictionary<string, object>))); } else if (result is ArrayList) { result = new List<object>((result as ArrayList).ToArray()); } return this.Dictionary.ContainsKey(binder.Name); } }
变stream器
public class DynamicJsonConverter : JavaScriptConverter { public override object Deserialize(IDictionary<string, object> dictionary, Type type, JavaScriptSerializer serializer) { if (dictionary == null) throw new ArgumentNullException("dictionary"); if (type == typeof(object)) { return new DynamicJsonObject(dictionary); } return null; } public override IDictionary<string, object> Serialize(object obj, JavaScriptSerializer serializer) { throw new NotImplementedException(); } public override IEnumerable<Type> SupportedTypes { get { return new ReadOnlyCollection<Type>(new List<Type>(new Type[] { typeof(object) })); } } }
用法（ 样本json ）：
JavaScriptSerializer jss = new JavaScriptSerializer(); jss.RegisterConverters(new JavaScriptConverter[] { new DynamicJsonConverter() }); dynamic glossaryEntry = jss.Deserialize(json, typeof(object)) as dynamic; Console.WriteLine("glossaryEntry.glossary.title: " + glossaryEntry.glossary.title); Console.WriteLine("glossaryEntry.glossary.GlossDiv.title: " + glossaryEntry.glossary.GlossDiv.title); Console.WriteLine("glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.ID: " + glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.ID); Console.WriteLine("glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.GlossDef.para: " + glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.GlossDef.para); foreach (var also in glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.GlossDef.GlossSeeAlso) { Console.WriteLine("glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.GlossDef.GlossSeeAlso: " + also); }
这个方法必须返回true，否则会抛出错误。 例如，如果一个键不存在，你可以抛出一个错误。
返回true和清空result将返回一个空值，而不是抛出错误。
public override bool TryGetMember(GetMemberBinder binder, out object result) { if (!this.Dictionary.ContainsKey(binder.Name)) { result = ""; } else { result = this.Dictionary[binder.Name]; } if (result is IDictionary<string, object>) { result = new DynamicJsonObject(result as IDictionary<string, object>); } else if (result is ArrayList && (result as ArrayList) is IDictionary<string, object>) { result = new List<DynamicJsonObject>((result as ArrayList).ToArray().Select(x => new DynamicJsonObject(x as IDictionary<string, object>))); } else if (result is ArrayList) { result = new List<object>((result as ArrayList).ToArray()); } return true; // this.Dictionary.ContainsKey(binder.Name); }
我只是觉得整个例子会很有用。 这是这个问题的例子。

我试图使用上面的代码，但没有工作。 Google返回的JSON结构非常不同，在助手函数中有一个非常重要的缺失：调用DataContractJsonSerializer.ReadObject() ，实际将JSON数据反序列化到对象中。
这是2011年的代码：
using System; using System.Runtime.Serialization; using System.Runtime.Serialization.Json; using System.IO; using System.Text; using System.Collections.Generic; namespace <YOUR_NAMESPACE> { public class JSONHelper { public static T Deserialise<T>(string json) { T obj = Activator.CreateInstance<T>(); MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json)); DataContractJsonSerializer serialiser = new DataContractJsonSerializer(obj.GetType()); obj = (T)serialiser.ReadObject(ms); ms.Close(); return obj; } } public class Result { public string GsearchResultClass { get; set; } public string unescapedUrl { get; set; } public string url { get; set; } public string visibleUrl { get; set; } public string cacheUrl { get; set; } public string title { get; set; } public string titleNoFormatting { get; set; } public string content { get; set; } } public class Page { public string start { get; set; } public int label { get; set; } } public class Cursor { public string resultCount { get; set; } public Page[] pages { get; set; } public string estimatedResultCount { get; set; } public int currentPageIndex { get; set; } public string moreResultsUrl { get; set; } public string searchResultTime { get; set; } } public class ResponseData { public Result[] results { get; set; } public Cursor cursor { get; set; } } public class GoogleSearchResults { public ResponseData responseData { get; set; } public object responseDetails { get; set; } public int responseStatus { get; set; } } }
要获得第一个结果的内容，请执行以下操作：
GoogleSearchResults googleResults = new GoogleSearchResults(); googleResults = JSONHelper.Deserialise<GoogleSearchResults>(jsonData); string contentOfFirstResult = googleResults.responseData.results[0].content;
感谢大家的帮助。 这是我最终的版本，它的工作得益于你的帮助！ 我只是展示了我所做的改变，其余的都来自乔忠的作品
public class GoogleSearchResults { [DataMember] public ResponseData responseData { get; set; } [DataMember] public string responseDetails { get; set; } [DataMember] public int responseStatus { get; set; } }
和
[DataContract] public class ResponseData { [DataMember] public List<Results> results { get; set; } }
