日期格式设定 S<

9.获取错误信息并到指定页面 hI+mx
LSX;|#AI
不要使用Response.Redirect,而应该使用Server.Transfer }^ g6Y3\
#:UP'v=w
e.g !>n^ ;u
// in global.asax i!|OFU6
protected void Application_Error(Object sender, EventArgs e) { E46+B2_~zk
if (Server.GetLastError() is HttpUnhandledException) JO|%Vpco
Server.Transfer("MyErrorPage.aspx"); xI'sprNa_1
DlD;rL=
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) m2i'$^a#
} 1FkS$ j8:
e-4 Qw#cw
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 " R=,W{=
