9.获取错误信息并到指定页面 "OkZ

不要使用Response.Redirect,而应该使用Server.Transfer :c )R6=v
UaQW<6+
e.g 9M|#X1r{%{
// in global.asax VRY@}>W'
protected void Application_Error(Object sender, EventArgs e) { l_+q a6C*
if (Server.GetLastError() is HttpUnhandledException) SjJ$Oinc
Server.Transfer("MyErrorPage.aspx"); *(i%\
r<P? F
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) &js$qgY
} *(/b{!~
4{6,Sx
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?.VW/"
