9.获取错误信息并到指定页面 75hFyh;u
PK.h E{R
不要使用Response.Redirect,而应该使用Server.Transfer {|Mxvp*Hg
xoz*UA.
e.g |*]X\UE
// in global.asax zCj*:n
protected void Application_Error(Object sender, EventArgs e) { =#POMK".6
if (Server.GetLastError() is HttpUnhandledException) ((RpT0rP\
Server.Transfer("MyErrorPage.aspx"); #whO2Mv
fJF8/IQ4
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) V\k5h
} 7)8rc(58
np'M4^E;
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 w{YtTZp3
