日期格式设定 1U,1)<z~u

9.获取错误信息并到指定页面 $8crN$ye

不要使用Response.Redirect,而应该使用Server.Transfer \))=gu)I

e.g u1c%T@w>Lz
// in global.asax 1HPx|nmE]
protected void Application_Error(Object sender, EventArgs e) { tM#lFmdd\P
if (Server.GetLastError() is HttpUnhandledException) @;?T~^nGj
Server.Transfer("MyErrorPage.aspx"); _0 m\[t.
X.TI>90{
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) z~\t|Z]G,|
} EbZdas!l
1>Q'R
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 <vUVP\u~$
