9.获取错误信息并到指定页面 9+'@
Ere?d~8
不要使用Response.Redirect,而应该使用Server.Transfer 5D]30
#Cg}!38
e.g '&.)T2Kw
// in global.asax GCP{Z]u
protected void Application_Error(Object sender, EventArgs e) { 9zoT6QP4
if (Server.GetLastError() is HttpUnhandledException) y~==waZw
Server.Transfer("MyErrorPage.aspx"); rR,+G%[(=4
IDGQIg
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) "}'8`k+d
} r
1l/) ;
xZ.~:V03\t
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 [l8V<*x%S9
