日期格式设定 v>yGsJnV'

9.获取错误信息并到指定页面 ;Fwm1ezx0
2!"\;/
不要使用Response.Redirect,而应该使用Server.Transfer HCn]#
D+@/x{wX2
e.g Oujlm|
// in global.asax 1' @lg*^9
protected void Application_Error(Object sender, EventArgs e) { AU${0#WV_
if (Server.GetLastError() is HttpUnhandledException) _sCJ3ZJ
Server.Transfer("MyErrorPage.aspx"); is_dPc
%o_0M^3W
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) bl!f5RO S(
} WEY97_@
dOYm 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 6{,K7FL
