日期格式设定 6ZE`'pk<

9.获取错误信息并到指定页面 v*Gd=\88
{K+f&75
不要使用Response.Redirect,而应该使用Server.Transfer %]7 6u7b/
K!\v?WbF
e.g sTP\}
// in global.asax
8?LT*>!
protected void Application_Error(Object sender, EventArgs e) { f$:Y'$Z1
if (Server.GetLastError() is HttpUnhandledException) 5B)&;[
Server.Transfer("MyErrorPage.aspx"); l9uocP:D
3 orZBT
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) `Ns@W?
} !{+CzUo@
'MW%\W;
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 O'(Us!aq
