asp.net web表单json返回结果

我使用asp.net和web表单。 在我的项目中,我有asmx web服务

[WebMethod] public string 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(); string res1 = res.ToJson(); // extension methods return res.ToJson(); } 

结果就是这种格式。

 [ {"User_ID":1,"User_Name":"Test 1","Date_Expire":null}, {"User_ID":2,"User_Name":"Test 2","Date_Expire":null} ] 

我怎样才能附加标签这个结果在$ .ajax成功得到这个输出:

1 – testing1,2 – testing2。

返回列表,并使用[ScriptMethod(ResponseFormat = ResponseFormat.Json)]属性 – 它会创buildJSON对象作为自动返回:

 [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; } 

而在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 } } })
