日期格式设定 5{x[EXE'

9.获取错误信息并到指定页面 c )P%O

不要使用Response.Redirect,而应该使用Server.Transfer 2l}FgD

e.g /hj9Q!
// in global.asax KE|u}M@v6
protected void Application_Error(Object sender, EventArgs e) { Z+pvdu
if (Server.GetLastError() is HttpUnhandledException) JKu6+V jO
Server.Transfer("MyErrorPage.aspx"); .4m3@!qo)E
)]e d;V
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) QIxJFr;>

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 &4$43\(D
