如何在Windows Phone 8中將好友列表綁定為longlistselector

Question

我在Windows Phone中進行應用聊天，我的類名為GetFriendResponse

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace RAMACHAT.Model
{

    public class FriendInfo
    {
        public bool success { get; set; }
        public int statusCode { get; set; }
        public string message { get; set; }
        public _user data { get; set; }

    }
    public class GetFriendResponse
    {
        public bool success { get; set; }
        public int statusCode { get; set; }
        public string message { get; set; }
        public string _id { get; set; }

        public List<_user> data { get; set; }
    }

和類_user為

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace RAMACHAT.Model
{
    public class _user
    {
        public string _id { get; set; }
        public string username { get; set; }
        public string avatar { get; set; }
        public bool isOnline { get; set; }
        public bool isFollow { get; set; }

    }
}



    }

現在我想在服務器響應用戶frendslist時將frendslist設為longlistselector

 string result = await App.client.getAllFriends();
            string resultHistory = await App.client.getChatHistory();
            resultObject = JsonConvert.DeserializeObject<GetFriendResponse>(result);
            var resultHistoryObject = JsonConvert.DeserializeObject<HistoryResponse>(resultHistory);

            List<AlphaKeyGroup.AlphaKeyGroup1<_user>> DataSource = AlphaKeyGroup.AlphaKeyGroup1<_user>.CreateGroups(resultObject.data,
                           System.Threading.Thread.CurrentThread.CurrentUICulture,
                           (_user s) => { return s.username; }, true);
            friendList.ItemsSource = DataSource; 

但是它不起作用，任何人都有修復它的想法，非常感謝！

由於您尚未共享設計代碼塊，因此可能是XAML頁面綁定的問題。 最好您將此 MSDN頁面用於longlistselector綁定。
