我的数据格式是 
{"result":[{"teamId":94885,"teamname":"asas"},{"teamId":132820,"teamname":"哈喽"},{"teamId":137710,"teamname":"幸福花"}]}想得到teamId teamname 绑定到下拉列表里 谁能帮忙弄下啊 谢谢啦~~ 

Answer 1

        string str = "[{\"result\":[{\"teamId\":94885,\"teamname\":\"asas\"},{\"teamId\":132820,\"teamname\":\"哈喽\"},{\"teamId\":137710,\"teamname\":\"幸福花\"}]}]";
        JavaScriptArray array = (JavaScriptArray)JavaScriptConvert.DeserializeObject(str);
        if (array.Count > 0)
        {
            JavaScriptObject obj = (JavaScriptObject)array[0];
            JavaScriptArray arr = (JavaScriptArray)obj["result"];
            foreach (JavaScriptObject o in arr)
            {
                Response.Write(o["teamId"] + "===" + o["teamname"] + "<br/>");
            }
        }
/*
下个Newtonsoft.Json.dll
结果：
94885===asas
132820===哈喽
137710===幸福花
*/

Answer 2

//刚自己给lz加了个中括号，现在按lz提供的字符串
        string str = "{\"result\":[{\"teamId\":94885,\"teamname\":\"asas\"},{\"teamId\":132820,\"teamname\":\"哈喽\"},{\"teamId\":137710,\"teamname\":\"幸福花\"}]}";
        JavaScriptObject json = (JavaScriptObject)JavaScriptConvert.DeserializeObject(str);
        if (json.Count > 0)
        {
            JavaScriptArray arr = (JavaScriptArray)json["result"];
            foreach (JavaScriptObject o in arr)
            {
                Response.Write(o["teamId"] + "===" + o["teamname"] + "<br/>");
            }
        }
/*
94885===asas
132820===哈喽
137710===幸福花
*/

Answer 3

一定要下载 Newtonsoft.Json.dll这个吗？
