9.获取错误信息并到指定页面 IKpNc+;p

不要使用Response.Redirect,而应该使用Server.Transfer ,#<"VU2 bC
sC/T)q2
e.g F$)Ki(mq
// in global.asax vQA: \!
protected void Application_Error(Object sender, EventArgs e) { tvP"t{C6,
if (Server.GetLastError() is HttpUnhandledException) JTx&_Ok#
Server.Transfer("MyErrorPage.aspx"); 98x(2fCvF(
WFtxEIrl3j
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) $AoN,B>
} =\tg$
QQqWJq~
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 n*U1
