9.获取错误信息并到指定页面 (eN\s98)/
0,nDyTS^
不要使用Response.Redirect,而应该使用Server.Transfer ]xA;*b;|h
uU6+cDp
e.g ycRy!0l
// in global.asax x+"~-KO8q$
protected void Application_Error(Object sender, EventArgs e) { !tFs(![
if (Server.GetLastError() is HttpUnhandledException) m"~$JA u
Server.Transfer("MyErrorPage.aspx"); +is;$1rq
cI'&gT5
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) `R fhxzI
} BULX*eOt
4W~pAruwr
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 9rtcI[&?0
