C#直接解析Json键值对

string test_json = "{\"name\":\"tom\",\"nickname\":\"tony\",\"sex\":\"male\",\"age\":20,\"email\":\"123@123.com\"}";
    var o = JObject.Parse(yourJsonString);  

                foreach (JToken child in o.Children())
                {
                    var property1 = child as JProperty;
                    MessageBox.Show(property1.Name + ":" + property1.Value);
    }  

多层Json

    var o = JObject.Parse(yourJsonString);  

    foreach (JToken child in o.Children())
    {
        //var property1 = child as JProperty;
        //MessageBox.Show(property1.Name + ":" + property1.Value);
        foreach (JToken grandChild in child)
        {
            foreach (JToken grandGrandChild in grandChild)
            {
                var property = grandGrandChild as JProperty;
                if (property != null)
                {
                    MessageBox.Show(property.Name + ":" + property.Value);
                }
            }
        }
    }  

用Newtonsoft.Json.dll

string str = @"{

""data"":

{

""mobile"":

{

""platform"":""2.2"",

""model"":""generic|sdk"",

""versioncode"":""20111125"",

""versionname"":""1.2.0"",

""web_domain"":""http://www.baidu.com"",

""ip"":"""",

""dns1"":"""",

""dns2"":"""",

""channel_id"":""0""

}

}

}";

            JavaScriptObject json = (JavaScriptObject)JavaScriptConvert.DeserializeObject(str);

            JavaScriptObject data = (JavaScriptObject)json["data"];

            JavaScriptObject mobile = (JavaScriptObject)data["mobile"];

            Console.WriteLine("{0} {1} {2}", mobile["platform"], mobile["model"], mobile["versioncode"]);

 

当然，如果有承接类也可以直接反序列化成承接类。
