Have a look at the system.web.script.serialization namespace (i think you will need .Net 3.5)
看看 system.web.script.serialization 命名空间（我认为你需要 .Net 3.5）

If you look here, you will see several different libraries for JSON on C#.
如果您查看此处，您将在 C# 上看到几个不同的 JSON 库。
You will find a version for LINQ as well as some others. There are about 7 libraries for C# and JSON.
您将找到 LINQ 和其他一些版本。C# 和 JSON 大约有 7 个库。

The .net framework supports JSON through JavaScriptSerializer. Here is a good example to get you started.
.net 框架通过 JavaScriptSerializer 支持 JSON。这是一个很好的例子，可以帮助您入门。
using System.Collections.Generic;
using System.Web.Script.Serialization;
namespace GoogleTranslator.GoogleJSON
{
public class FooTest
{
public void Test()
{
const string json = @"{
""DisplayFieldName"" : ""ObjectName"",
""FieldAliases"" : {
""ObjectName"" : ""ObjectName"",
""ObjectType"" : ""ObjectType""
},
""PositionType"" : ""Point"",
""Reference"" : {
""Id"" : 1111
},
""Objects"" : [
{
""Attributes"" : {
""ObjectName"" : ""test name"",
""ObjectType"" : ""test type""
},
""Position"" :
{
""X"" : 5,
""Y"" : 7
}
}
]
}";
var ser = new JavaScriptSerializer();
ser.Deserialize<Foo>(json);
}
}
public class Foo
{
public Foo() { Objects = new List<SubObject>(); }
public string DisplayFieldName { get; set; }
public NameTypePair FieldAliases { get; set; }
public PositionType PositionType { get; set; }
public Ref Reference { get; set; }
public List<SubObject> Objects { get; set; }
}
public class NameTypePair
{
public string ObjectName { get; set; }
public string ObjectType { get; set; }
}
public enum PositionType { None, Point }
public class Ref
{
public int Id { get; set; }
}
public class SubObject
{
public NameTypePair Attributes { get; set; }
public Position Position { get; set; }
}
public class Position
{
public int X { get; set; }
public int Y { get; set; }
}
}

Try the Vici Project, Vici Parser. It includes a JSON parser / tokeniser. It works great, we use it together with the MVC framework.
试试 Vici 项目，Vici Parser。它包括一个 JSON 解析器/标记器。它工作得很好，我们将它与 MVC 框架一起使用。

I forgot to say that it is open source so you can always take a look at the code if you like.
我忘了说它是开源的，所以你可以随时查看代码。

You should also try my ServiceStack JsonSerializer- it's the fastest .NET JSON serializer at the moment based on the benchmarks of the leading JSON serializersand supports serializing any POCO Type, DataContracts, Lists/Dictionaries, Interfaces, Inheritance, Late-bound objects including anonymous types, etc.
您还应该尝试我的 ServiceStack JsonSerializer- 它是目前最快的 .NET JSON 序列化器，基于领先的 JSON 序列化器的基准测试，并支持序列化任何 POCO 类型、数据合同、列表/字典、接口、继承、后期绑定对象，包括匿名类型等。
Basic Example
基本示例
var customer = new Customer { Name="Joe Bloggs", Age=31 };
var json = customer.ToJson();
var fromJson = json.FromJson<Customer>();
Note: Only use Microsofts JavaScriptSerializer if performance is not important to you as I've had to leave it out of my benchmarks since its up to 40x-100xslower than the other JSON serializers.
注意：只有在性能对您不重要的情况下才使用 Microsoft 的 JavaScriptSerializer，因为我不得不将它排除在我的基准测试之外，因为它比其他 JSON 序列化程序慢40 到 100 倍。

To answer your first question, Microsoft does ship a DataContractJsonSerializer: see msdn How to: Serialize and Deserialize JSON Data
要回答您的第一个问题，Microsoft 确实提供了 DataContractJsonSerializer：请参阅 msdn How to: Serialize and Deserialize JSON Data

To give a more up to date answer to this question: yes, .Net includes JSON seriliazer/deserliazer since version 3.5 through the System.Runtime.Serialization.Json Namespace: http://msdn.microsoft.com/en-us/library/system.runtime.serialization.json(v=vs.110).aspx
要对此问题提供最新答案：是的，.Net 从 3.5 版开始通过 System.Runtime.Serialization.Json 命名空间包含 JSON seriliazer/deserliazer：http: //msdn.microsoft.com/en-us/library /system.runtime.serialization.json(v=vs.110).aspx
But according to the creator of JSON.Net, the .Net Framework compared to his open source implementation is very much slower.
但是根据 JSON.Net 的创建者的说法，.Net Framework 与他的开源实现相比要慢得多。
