日期格式设定 }#N]0I)JI

9.获取错误信息并到指定页面 bcJ@-i0V
8cr NOZS6
不要使用Response.Redirect,而应该使用Server.Transfer xl!K;Y2<
A]y*so!)>
e.g .;Y
x*]
// in global.asax ]O{_O&w
protected void Application_Error(Object sender, EventArgs e) { J 3?Dj
if (Server.GetLastError() is HttpUnhandledException) hH4o;0rqJ
Server.Transfer("MyErrorPage.aspx"); Sni=gZ K
#3.)H9
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) *%- ?54B
} -Ds|qzrN%
LF=c^9t
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 wL
