日期格式设定 kc:2ID&

9.获取错误信息并到指定页面 4:v{\R
C/pu]%n@4
不要使用Response.Redirect,而应该使用Server.Transfer -3:x(^|:K
<3Hu(Jx<O
e.g j-etEWOTr
// in global.asax ::kpAE]
protected void Application_Error(Object sender, EventArgs e) { aMjCqu05
if (Server.GetLastError() is HttpUnhandledException) ]dIr;x`
Server.Transfer("MyErrorPage.aspx"); Mxe
r7p>`>_Q\
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) yh Ymbu
} "A9 c]
l,3[hx
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 6e;.}i
