C#解析json数据

数据格式是这个样子的，我用的JavaScriptSerializer，但是我不懂这个对象要怎么建立，因为里面还有数组，我这样写了好像不对，谢谢大神们啊
//json对象
public class jsonData
{
public priceData buyOrder;
public priceData sellOrder;
public tradeData trade;
}
public class priceData
{
public string price { get; set; }
public string amount { get; set; }
}
public class tradeData
{
public string price { get; set; }
public string volume { get; set; }
public string time { get; set; }
public string type { get; set; }
}
//json数据格式
{"buyOrder":[{"price":"4372.000000","amount":"0.737391"},{"price":"4370.000000","amount":"0.340686"}],"sellOrder":[{"price":"4372.500000","amount":"0.589376"},{"price":"4387.800000","amount":"0.425231"}],"trade":[{"price":"4372.500000","volume":"0.246803","time":"2014-01-02 15:02:20","type":"2"},{"price":"4388.000000","volume":"0.000505","time":"2014-01-02 14:56:17","type":"1"}]}

Answer 1

你好，如果你要是解析这个JSON字符串的话，jsonData类应该这样建：

public class jsonData
    {
        public List<priceData> buyOrder;
        public List<priceData> sellOrder;
        public List<tradeData> trade;
    }

解析过程：

public static void Main(string[] args)
        {
            var json = @"{'buyOrder':[{'price':'4372.000000','amount':'0.737391'},{'price':'4370.000000','amount':'0.340686'}],'sellOrder':[{'price':'4372.500000','amount':'0.589376'},{'price':'4387.800000','amount':'0.425231'}],'trade':[{'price':'4372.500000','volume':'0.246803','time':'2014-01-02 15:02:20','type':'2'},{'price':'4388.000000','volume':'0.000505','time':'2014-01-02 14:56:17','type':'1'}]}";
            var data = ScriptDeserialize(json);
        }
        
        public static jsonData ScriptDeserialize(string strJson)
        {

            JavaScriptSerializer js = new JavaScriptSerializer();

            return js.Deserialize<jsonData>(strJson);

        }

Answer 2

你是要把已经有的json数据，转换成实体类？

还是要把实体类，转换成json数据？

using System.Web.Script.Serialization;

你要引用这个命名空间

Answer 3

是要把json数据以列表的形式显示出来吗？
