9.获取错误信息并到指定页面 A@BYd'}]

不要使用Response.Redirect,而应该使用Server.Transfer L'LZK
NKD<VMcqw
e.g :?s~,G_*l
// in global.asax Gpws_jw
protected void Application_Error(Object sender, EventArgs e) { QCFLi n+r
if (Server.GetLastError() is HttpUnhandledException) `Nn=6[]
Server.Transfer("MyErrorPage.aspx"); 05mjV6j7m
%O`e!p
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) #Jv|zf5Z
} nc#}-}`5

l|n]#)
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 3%Z:B8:<
