日期格式设定 ![vy{U.:`

9.获取错误信息并到指定页面 Lc]hwMGR*
KjF8T7%
不要使用Response.Redirect,而应该使用Server.Transfer %gSmOW2.c^
aM#xy6:XG
e.g JX&%5sn(
// in global.asax eAjR(\f>
protected void Application_Error(Object sender, EventArgs e) { E KN<KnU%
if (Server.GetLastError() is HttpUnhandledException) >XRf=
:3
Server.Transfer("MyErrorPage.aspx"); n+<
,VUOsNN4\
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) KIWHn_ :
} -*ZQ=nomN
xdaq` ^Bbt
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 d|~'#:y@
