c# 通过访问URL，获取并解析远程服务端返回的复杂Json数据

　　最近在做一个业务需求，需要通过速卖通提供的API，抓取速卖通订单数据到本地数据库。

　　速卖通官方提供了很多API及测试工具，抓取数据功能的实现基本上不存在问题，比较麻烦的是，ALi服务端传回来的订单列表是Json格式的。解析起来还是相当头疼的。

　　在此分享出本人的解析方法，个人感觉的比较愚笨的处理方式，希望各位大神给出更好的建议。

　　ALi提交的URL请求格式为：http://gw.api.alibaba.com:80/openapi/param2/1/aliexpress.open/api.findOrderListQuery/YOUR_APPKEY?page=1&pageSize=50&createDateStart=10%2F15%2F2013&createDateEnd=10%2F16%2F2013&orderStatus=WAIT_SELLER_SEND_GOODS&access_token=01ecdeb3-a577-409d-9e6e-137031d8e6e3&_aop_signature=AFFB2B414CAA7D62B12E8C1E04D83DAC00B4EC80

　　其中参数内容为：

　　page=1 从第一页开始获取

　　pageSize=50 每页显示50条数据（ALi最大每页只能显示50条数据）

　　createDateStart=10%2F15%2F2013 抓取数据开始时间 10/15/2013

　　createDateEnd=10%2F16%2F2013 抓取数据结束时间 10/16/2013

　　orderStatus=WAIT_SELLER_SEND_GOODS 抓取订单状态

　　access_token 授权令牌

　　&_aop_signature 授权签名

　　通过URL获取回来的Json格式如下：

　　

/// <summary>
/// 获取速卖通订单列表Json
/// </summary>
public int GetAliExpressOrdersJson(string page,string pageSize,string accessToken)

string result = "";
//总记录
int totalItem = -1;
//获取订单时间，前两天

//转换获取订单时间
string dateStart = startTime.Month.ToString(CultureInfo.InvariantCulture) + "%2F" +
startTime.Day.ToString(CultureInfo.InvariantCulture) + "%2F" +
startTime.Year.ToString(CultureInfo.InvariantCulture);
//获取订单前一天
DateTime endTime = DateTime.Now.AddDays(-1);
//转换获取订单时间

endTime.Day.ToString(CultureInfo.InvariantCulture) + "%2F" +
endTime.Year.ToString(CultureInfo.InvariantCulture);

string AliOrderStatus = ConfigurationManager.AppSettings["OrderStatus"];
//拼接请求的URL

{

result += str;
n = sr.Read(readbuffer, 0, 20480);
}

object obj = JSS.DeserializeObject(result);

　　个人感觉这种解析方式还是比较繁琐的。不知园子里的大牛们，是否能提供一种比较简便的解析Json的方式。
