而是返回列表，并使用[scriptMethod（ResponseFormat = ResponseFormat.Json）]属性-
它将自动创建JSON对象作为返回：
[WebMethod][scriptMethod(ResponseFormat = ResponseFormat.Json)] public List<RetUsers> GetSomething(){ // avoid circual reference(parent child) List<RetUsers> res = repo.GetAllUser().Select(c => new RetUsers {User_ID = c.User_ID,User_Name = c.User_Name,Date_Expire = c.Date_Expire }).ToList(); return res;}在JS方面：
$.ajax({ type: "POST",async: true,url: YourMethodUrl,data: {some data},contentType: "application/json; charset=utf-8",dataType: "json", success: function(msg) { var resultAsJson = msg.d // your return result is JS array // Now you can loop over the array to get each object for(var i in resultAsJson) { var user = resultAsJson[i] var user_name = user.User_Name // Here you append that value to your label } }})
