推荐答案

规则一:在编写基于Web的应用程序时，请不要使用 Messagebox.Show
它显示在服务器上而不是客户端上.当消息框出现在用户看不到的地球另一端的服务器上时，它似乎在开发中起作用，但在生产中却以很大的方式失败，这在很大程度上是由于以下原因:
1)没有收到消息的用户-实际上他什么也没得到.
2)网络托管管理员，他开始热情地恨你...

Rule number one: When you are writing web based applications, do not use Messagebox.Show
It shows on the server not the client. It seems to work in developement, but fails in a very big way in production, when the message box appears on a server on the other side of the planet where the user can''t see it, much to the apoyance of:
1) The user, who doesn''t get the message - in fact he gets nothing.
2) The web host administrator, who begins to hate you with a passion...
