WebForm-博客园-6.0-空间(Space)-短信息(Msg)

ylbtech-Architecture:WebForm-博客园-6.0-空间(Space)-短信息(Msg)

博客园的空间短消息的实现。

1.A，概念

优点：

缺点：

1.B，结构截图

B.1, /msg/Inbox.aspx

B.2,/msg/Compose.aspx

B.3,/msg/Message.aspx

B.4,/msg/Outbox.aspx

B.5,/msg/Export.aspx

1.C，创建流程

C.1,写信息-->发件箱-->单个短信息查看【回复，转化，删除】

C.2,收件箱-->单个短信息查看【回复，转化，删除】

C.3,短信备份

1.D，功能实现代码(摘抄重要的代码段)

1.E，注意事项

注意事项：

当发送有一封短消息的时候，需用同时向短息表插入一条已发送记录（自己发信箱里）和一条接受记录（他人的收件箱）。
