//工具类

publicstaticList<T> JSONStringToList<T>(thisstring JsonStr)

{

        JavaScriptSerializer Serializer = newJavaScriptSerializer();

        List<T> objs = Serializer.Deserialize<List<T>>(JsonStr);

        return objs;

}

 

publicstatic T Deserialize<T>(string json)

{

        T obj = Activator.CreateInstance<T>();

        using (MemoryStream ms = newMemoryStream(Encoding.UTF8.GetBytes(json)))

        {

        DataContractJsonSerializer serializer = newDataContractJsonSerializer(obj.GetType());

        return (T)serializer.ReadObject(ms);

}

}

 

 

好了，我们来测试下

stringJsonStr = "[{Name:'苹果',Price:5.5},{Name:'橘子',Price:2.5},{Name:'柿子',Price:16}]";

List<Product> products = newList<Product>();

products = JSONStringToList<Product>(JsonStr);

//Response.Write(products.Count());

foreach(var item in products)

{

   Response.Write(item.Name + ":" + item.Price + "<br />");

}

//实体类

public class Product

{

        publicstring Name { get; set; }

        publicdouble Price { get; set; }

}

结果：

苹果:5.5

橘子:2.5

柿子:16
