在 C# 中解析 JSON

【中文标题】在 C# 中解析 JSON【英文标题】：Parse JSON in C# 【发布时间】：2010-11-15 18:56:02 【问题描述】：我正在尝试从 Google AJAX 搜索 API 解析一些 JSON 数据。我有this URL，我想将其分解以便显示结果。我目前已经编写了这段代码，但是对于下一步该做什么我很迷茫，尽管有许多简化 JSON 字符串的示例。
一般来说，作为 C# 和 .NET 的新手，我一直在努力为我的 ASP.NET 页面获得真正的文本输出，因此建议我尝试 JSON.NET。谁能指出我正确的方向，只需编写一些从 Google AJAX 搜索 API 接收 JSON 并将其打印到屏幕上的代码？
编辑：全部修复！所有结果都运行良好。再次感谢 Dreas Grech！

Json.NET 使用与上述示例相同的 JSON 和类。
GoogleSearchResults g1 = JsonConvert.DeserializeObject<GoogleSearchResults>(json);

【问题讨论】：
您的GoogleSearchResults 类型具有同名的字段和属性。尝试使用前导下划线重命名您的字段（任何可以消除两者之间歧义的内容）。
我在 json.net james.newtonking.com/pages/json-net.aspx 上取得了不错的成绩
我会在上面提到@kenny。与 JSON.NET 相比，.NET JSON 序列化程序的性能绝对糟糕。
【参考方案1】：
[更新]
我刚刚意识到为什么您没有收到结果……您的 Deserialize 方法中缺少一行。您忘记将结果分配给您的 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，这里有与上面代码等效的 Serialize/Deserialize 方法..
反序列化：
JsonConvert.DeserializeObject<T>(string json);
序列化：
JsonConvert.SerializeObject(object o);
这已经是 Json.NET 的一部分，因此您可以在 JsonConvert 类上调用它们。
链接：Serializing and Deserializing JSON with Json.NET
现在，您获得 *** 的原因是因为您的 Properties。
以这个为例：
[DataMember]
public string unescapedUrl
get return unescapedUrl; // <= this line is causing a Stack Overflow
set this.unescapedUrl = value;
请注意，在getter 中，您正在返回实际属性（即，该属性的 getter 一遍又一遍地调用自身），因此您正在创建无限递归。
属性（在 2.0 中）应该这样定义：
string _unescapedUrl; // <= private field
[DataMember]
public string unescapedUrl
get return _unescapedUrl;
set _unescapedUrl = value;
您有一个私有字段，然后在 getter 中返回该字段的值，并在 setter 中设置该字段的值。
顺便说一句，如果您使用的是 3.5 框架，则可以这样做并避免使用支持字段，并让编译器来处理：
public string unescapedUrl get; set;
【讨论】：
据我所知，这台机器还没有更新到 3.5，所以我假设是 2.0。我已经尝试过 get/set 的事情，但它没有用，但那部分似乎工作得很好。 ...hmm，但如果我没记错的话，DataContractJsonSerializer 仅在 3.5 框架中可用，不是吗？
这很奇怪，因为 Visual Studio 在我的代码中识别 DataContractJsonSerializer 似乎没有问题，但它不喜欢使用 (get; set;)。
不管怎样，我已经将这台新机器升级到3.5，所以应该没有任何问题。
我添加了这行额外的代码，如果我尝试编写 g1.responseData.results，我会在屏幕上打印“results[]”，其他所有内容都打印为它们的名称（例如 g1 .responseData 打印“responseData”和 g1 打印“GoogleSearchResults”）。【参考方案2】：
您的数据类与 JSON 对象不匹配。改用这个：
[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，您不必实例化该类来获取其类型以进行反序列化：
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);
【讨论】：
我刚刚尝试过，但我刚刚收到错误“找不到类型或命名空间名称 'IEnumerable'（您是否缺少 using 指令或程序集引用？）” . 没关系，我使用的是 System.Collections 而不是 System.Collection.Generic。它现在与该代码完美编译，但我需要做什么才能输出数据？ 检查我更新的帖子，因为我发现您的代码中缺少什么【参考方案3】：我发现了这种parse JSON into a dynamic object 的方法，它扩展了DynamicObject 和javascriptConverter 以将字符串转换为对象。
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);
转换器
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（sample 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。如果密钥不存在，则可以抛出错误。
返回true 并清空result 将返回一个空值，而不是引发错误。
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);
