安卓开发，加载数据显示ListView ListAdapter 问题

Question

安卓开发，加载数据显示ListView正常

listview = FindViewById(Resource.Id.lvKcxx);
//加载数据
datas = new List();
//datas.Add(new JxglList { title = "Elephant1", postman = "Big and Gray, but what the hey", addtime = "2015-11-12 12:12:12" });
//datas.Add(new JxglList { title = "Elephant2", postman = "Big and Gray, but what the hey", addtime = "2015-11-12 12:12:12" });
//datas.Add(new JxglList { title = "Elephant3", postman = "Big and Gray, but what the hey", addtime = "2015-11-12 12:12:12" });

        //listview.Adapter = new DataListAdapter(this, datas); 

连接数据库后，换
datas.Add(new JxglList { title = list[i]["Title"].ToString(), postman = list[i]["PostMan"].ToString(), addtime = list[i]["AddTime"].ToString() });
出错
