日期格式设定 JBi*P.79^

9.获取错误信息并到指定页面 6G
#}Q/
LS7, a|
不要使用Response.Redirect,而应该使用Server.Transfer tKuVQH~D
Oy%''+g
e.g $})g?Q
// in global.asax #:[t^}
protected void Application_Error(Object sender, EventArgs e) { fQi4\m
if (Server.GetLastError() is HttpUnhandledException) [P&7i57
Server.Transfer("MyErrorPage.aspx"); v hpNpgz
{@+Ty]e
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ?AJKBW^
} Y0x%sz5
Nd$W0YN:
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/BM&r
