日期格式设定 ,BH@j%Jmy

9.获取错误信息并到指定页面 C_(
*>!Z%
caU0\VS
不要使用Response.Redirect,而应该使用Server.Transfer $|L
Sx
ynq}76 H0k
e.g N@2dA*T,
// in global.asax >tYm+coS
protected void Application_Error(Object sender, EventArgs e) { ohRjvJ'v|
if (Server.GetLastError() is HttpUnhandledException) q3mJ782p]
Server.Transfer("MyErrorPage.aspx"); D[4u+g?[}>
L5Ebc#
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ? E1<!~
} 7S-ys+
MDnKX?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 v_<rNc,z-s
