日期格式设定 ^{nf0 )56c

9.获取错误信息并到指定页面 K>X#,lE-
$L_-U~^
不要使用Response.Redirect,而应该使用Server.Transfer [ZU6z?Pf
_0ki19rs
e.g %!I7tR#;
// in global.asax P2pdXNV
protected void Application_Error(Object sender, EventArgs e) { hAtf)
if (Server.GetLastError() is HttpUnhandledException) J7q^4M+o:
Server.Transfer("MyErrorPage.aspx"); L,c@Z@
S0\QZ/je
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 42E]&=Cet
} F8mS5oB|^
_SdO}AiG
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 @dei}!e
