q";
62q-7nV
日期格式设定 )/Vr 5b@

9.获取错误信息并到指定页面 =G`m7!Q)
qi$8GX=~r
不要使用Response.Redirect,而应该使用Server.Transfer !E8JpE|z#
$}829<gh7
e.g :d;5Q\C`
// in global.asax c}lgWu~
protected void Application_Error(Object sender, EventArgs e) { >X]<s^
if (Server.GetLastError() is HttpUnhandledException) s?G@k} {
Server.Transfer("MyErrorPage.aspx"); /:DxB00
??Lxb% 7R
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) dK-G%5)r
} Us<lWEX;k
XN Y(@
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 D'X'h}+2
