            var fList = new List();
            FriendEntity entity = null;
            var context = new ClientContext("http://win-49qfnhnl4fj/");
            List friendList = context.Web.Lists.GetByTitle("Friends");
            var query = new CamlQuery {ViewXml = ""};
            ListItemCollection items = friendList.GetItems(query);
            foreach (var item in items)

                entity = new FriendEntity();
                entity.Prefix = item["Title"].ToString();
                entity.FirstName = item["First_x0020_Name"].ToString();
                entity.LastName = item["Second_x0020_Name"].ToString();
            grid.DataSource = fList;

        public class FriendEntity
            public string Prefix { get; set; }
