y^Kph# F"
日期格式设定 0B&Y]*
DataFormatString="{0:yyyy-MM-dd}" &S]@Ot<z

9.获取错误信息并到指定页面 ,0~9dS
:l&V]}:7*
不要使用Response.Redirect,而应该使用Server.Transfer ^#1.l=s
?(m
jx
e.g tBT<EV{ G
// in global.asax AfP'EP0m
protected void Application_Error(Object sender, EventArgs e) { 9D}/\jM
if (Server.GetLastError() is HttpUnhandledException) ,FMx5$
Server.Transfer("MyErrorPage.aspx"); ivz>dJ ?T
:ORR_f`>
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) .G(llA}
} 7&"n`@(.!
}X_;X_\3;'
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 T4 N~(Fi)
