本文介绍了如何使用System.Web.Helpers库中的Json类以及JavaScriptSerializer进行JSON字符串的解析与反序列化。通过实例展示了如何读取JSON数据，并提供了适用于.NET框架的代码示例。

If you are happy to have a dependency upon the System.Web.Helpers assembly, then you can use the Json class:

dynamic data = Json.Decode(json);

It is included with the MVC framework as an additional download to the .NET 4 framework. Be sure to give Vlad an upvote if that's helpful! However if you cannot assume the client environment includes this DLL, then read on.

An alternative deserialisation approach is suggested here. I modified the code slightly to fix a bug and suit my coding style. All you need is this code and a reference to System.Web.Extensions from your project:

You can use it like this:

string json = ...;

var serializer = new JavaScriptSerializer();

serializer.RegisterConverters(new[] { new DynamicJsonConverter() });

dynamic obj = serializer.Deserialize(json, typeof(object));

So, given a JSON string:

{ "Items":[

{ "Name":"Apple", "Price":12.3 },

{ "Name":"Grape", "Price":3.21 } ],

 "Date":"21/11/2010" }

The following code will work at runtime:

dynamic data = serializer.Deserialize(json, typeof(object));

data.Date; // "21/11/2010"

data.Items.Count; // 2

data.Items[0].Name; // "Apple"

data.Items[0].Price; // 12.3 (as a decimal)

data.Items[1].Name; // "Grape"

data.Items[1].Price; // 3.21 (as a decimal)
