我将下面三个数据项都注释以后发现序列化会产生一个240byte的dat文件
//addresses.Add("Jeff", "123 Main Street, Redmond, WA 98052");
//addresses.Add("Fred", "987 Pine Road, Phila., PA 19116");
//addresses.Add("Mary", "PO Box 112233, Palo Alto, CA 94301");
当放开以后,会产生387byte的文件如果应用是在本机的话,不会有任何问题,这点冗余的数据量可以忽略不计
但如果程序是在网络上走的话,可能这些冗余的数据就很不爽了
而且.net的二进制序列化的格式只有.net认识,如果设计到其他平台的数据兼容性问题等就会遇到很大的麻烦关于该问题大家有什么看法可以发我email: [email protected]
