            var room = (from r in db.Rooms
                        where r.RoomID == Convert.ToInt32(lblRoomId.Text)

            lblRoomId.Text = room.RoomID.ToString();
            lblRoomName.Text = room.Name;
        }

推荐答案

错误消息输入字符串格式不正确."表示在lblRoomId中输入的数据不是可以转换为整数的数字-它包含的字符不是0-> 9

The error message "Input string was not in a correct format." means that the data entered in lblRoomId is not a number that can be converted to an integer - it contains characters which are not 0->9
