asp.net2.0中到底怎么样扩展membership?一直困惑我的问题!谢谢!

Question

扩展membership可能是很多刚接触2.0的朋友的第一个问题,我搜了很多这方面的资料,但感觉都不是说的特别仔细,所以在此请教一下,希望做过这方面东西的朋友可以把代码共享出来让大家看看啊...给我们解决一下这个第一步,谢谢!有两个小问题.
1: 数据库是修改微软的那个表还是做一个关联表?
2: 听说是写一个新类继承MemberShip类,有没有这方面的例子?

Answer 1

昨天我找了那个membership provider. 我还有两个小问题要问一下: 
1. 比如我要给会员资料添加一个地址信息的字段,我需要修改那份数据库里面的表和存储过程吗? 
2. 我写一个新类继承MembershipProvider,是不是需要override里面的所有方法啊,还是只需要覆盖其中的几个? 
谢谢谢谢!!!!

Answer 2

我在应用的时候一般采用两种方法:
一:profile
二:自己建立一个memberinfo表,来进行扩充,但是这时候的查询要自己写了。
一般写成类,使用起来也是很方便的.

Answer 3

谢谢,我还有几个问题不明白
1: profile的话,数据好象都是串行化的存在aspnet_Profile这个表中,这样好么?
2: 自己建立一个memberinfo表,需要建立一个类来继承Membership吧？有没有写好的代码供我们学习一下啊？谢谢！！
