在于json。超级郁闷。下载了Newtonsoft.Json,可是没有JavaScriptArray属性，这是为什么呀
我想要取新浪微博API返回的JSON格式的值，因为本人没接触过这个，所以返回的json格式值解析不了，在网上找了一天了，终于看到有一个Newtonsoft.Json.dll，可以很简单的取到json的值。。。
可现在郁闷的是，我下载了Newtonsoft.Json.dll （我是vs2008 用NET3.5），引用上去后，命名空间也写了，可是就是找不到JavaScriptArray，
using System.Json;using Newtonsoft.Json;
string jsonStr = "{'order_no':'1205281338370004556','access_item':[{'commodity_id':'EZG20111130112304161','color':'red','size':'24','complex_access':'','access_content':''},{'commodity_id':'EZG20111130112304161','color':'','size':'','complex_access':'','access_content':''}]}"; JavaScriptObject jObject = JavaScriptConvert.DeserializeObject(jsonStr) as JavaScriptObject; Console.WriteLine(jObject["order_no"]); JavaScriptArray array = jObject["access_item"] as JavaScriptArray; foreach (JavaScriptObject o in array) { Console.WriteLine("commodity_id:{0} color:{1} size:{2} complex_access:{3}", o["commodity_id"], o["color"], o["size"], o["complex_access"]); }

应该是dll的版本问题，你的应该较新
修改如下
string jsonStr = "{'order_no':'1205281338370004556','access_item':[{'commodity_id':'EZG20111130112304161','color':'red','size':'24','complex_access':'','access_content':''},{'commodity_id':'EZG20111130112304161','color':'','size':'','complex_access':'','access_content':''}]}"; JObject jObject = JsonConvert.DeserializeObject(jsonStr) as JObject; JArray array = jObject["access_item"] as JArray; foreach (JObject o in array) { Console.WriteLine("commodity_id:{0} color:{1} size:{2} complex_access:{3}", o["commodity_id"], o["color"], o["size"], o["complex_access"]); }

教楼主个好办法无需第三方控件。
public class XLJson
{
public List<UserInfo> users { get; set; }
public string next_cursor { get; set; }
public string ious_cursor { get; set; }
public string total_number { get; set; }
}
public class UserInfo
{
public string id { get; set; }
public string city { get; set; }
}
新建个类如上
string jsonstr = @"

JavaScriptSerializer js = new JavaScriptSerializer();
XLJson xljson = js.Deserialize<XLJson>(jsonstr);
下面是调用法
