var info = from p in entity.Users where p.ID >= 10 orderby p.ID descending select p;
foreach (var item in info)

    Console.WriteLine("ID:" + item.ID + " " + "登录名:" + item.LoginName + " " + "密码:" + item.Password);
}

var info2 = entity.Users.Where<User>(p => p.ID >= 10).OrderByDescending(p => p.ID);
foreach (var item in info)

}

try

    string strSQL2 = "SELECT * FROM Users WHERE ID>=10 ORDER BY ID DESC";
    var info4 = entity.Database.SqlQuery<User>(strSQL2);
