9.获取错误信息并到指定页面 -C-OG}XjI
@W\4UX3dK
不要使用Response.Redirect,而应该使用Server.Transfer D7WI(j\
]RXtC*
e.g g;#KBxE
// in global.asax
2C33;?M
protected void Application_Error(Object sender, EventArgs e) { j)tCr Py
if (Server.GetLastError() is HttpUnhandledException) LH/&\k
Server.Transfer("MyErrorPage.aspx"); Ik-E4pxKo
a3dzok
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) Hl2f`GZ
} oz0n$`O$/
w^rb|mKo
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 |;U=YRi
