日期格式设定 ICpAt~3[M

9.获取错误信息并到指定页面 V n7*JS
vV6<^W:9F
不要使用Response.Redirect,而应该使用Server.Transfer Sw:7pByjI
oNr-Q& C,
e.g H[{F'c[e
// in global.asax E8!e:l
=Q
protected void Application_Error(Object sender, EventArgs e) { LVX[uWEM
if (Server.GetLastError() is HttpUnhandledException) d<% z
1Dj2
Server.Transfer("MyErrorPage.aspx"); t;\kR4P
81](T<
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) !4]TXH0f
} ]-PH^H
{^
qcx 8
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 .O74V~T
