有方法，帮你想一下

[wind_cloud2011]

using Newtonsoft.Json;
  string jj = "{\"3\":{\"i\":3,\"n\":\"海淀\",\"t\":2},\"2\":{\"i\":2,\"n\":\"北京\",\"t\":1},\"1\":{\"i\":1,\"n\":\"中国\",\"t\":0},\"7\":{\"i\":7,\"n\":\"天河\",\"t\":6},\"6\":{\"i\":6,\"n\":\"广州\",\"t\":52},\"4\":{\"i\":4,\"n\":\"五道口\",\"t\":3}}";
            JObject jo = JObject.Parse(jj);
            string[] values = jo.Properties().Select(item => item.Value.ToString()).ToArray();
            JObject jo1 = JObject.Parse(values[5]);
            string[] values1 = jo1.Properties().Select(item => item.Value.ToString()).ToArray();
            MessageBox.Show(values1[0]);

源文件是http://images04.edeng.cn/js/blue/g.js?ver=13134这个，要获取这里面最后一个等级的地区，如北京、海淀、五道口，知道北京这个信息，要获取五道口i的值，winform下，怎么获取？

你引用Newtonsoft.Json;，测试一下我上面的代码，string[] values，就取得每组数据，values[5]就是最后一组数据，values1[0])则是取得最后一组{\"i\":4,\"n\":\"五道口\",\"t\":3}中的第一个i的值，其它值类推

http://images04.edeng.cn/js/blue/g.js?ver=13134返回是josn数据，你下载到本地，再从中截取

var result= json对象.4;

楼主可以试试fastCSharp转换成实体数组

        class add
        {
            public int i;
            public string n;
            public int t;
        }
            string json = @"{""3"":{""i"":3,""n"":""海淀"",""t"":2},""2"":{""i"":2,""n"":""北京"",""t"":1},""1"":{""i"":1,""n"":""中国"",""t"":0},""7"":{""i"":7,""n"":""天河"",""t"":6},""6"":{""i"":6,""n"":""广州"",""t"":52},""4"":{""i"":4,""n"":""五道口"",""t"":3}}";
            add[] values = fastCSharp.setup.cSharp.json.parse.Get<add[]>(new fastCSharp.setup.cSharp.json.node(new fastCSharp.setup.cSharp.json.parser().Parse(json).Dictionary.Values.getList()));
