日期格式设定 Vz&!N/0i

9.获取错误信息并到指定页面 rfMzHY}%
h|1 /Q
(
不要使用Response.Redirect,而应该使用Server.Transfer {o[*S%Z"
DPZG_{3D
e.g B[O1^jdO
// in global.asax #}!Ge
protected void Application_Error(Object sender, EventArgs e) { {)0"?$C_H
if (Server.GetLastError() is HttpUnhandledException) !_gHIJiq}
Server.Transfer("MyErrorPage.aspx"); ZjXpMx,
tcf>9YsOr
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) t|aBe7t7
} #4*~ 4/

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 ceR zHq=
