9.获取错误信息并到指定页面 6wj o:I
u$C\#y7
不要使用Response.Redirect,而应该使用Server.Transfer ]1XtV<
J*MH`;-
e.g a/J Mg
// in global.asax 0nL
#-`S
protected void Application_Error(Object sender, EventArgs e) { Yj*T'<e
if (Server.GetLastError() is HttpUnhandledException) ~CbiKez
Server.Transfer("MyErrorPage.aspx"); ^<-)rzTI
%OB>FY:|
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ZI;*X~h
} (,jsZ!sl
n6.Z{Q'b
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 ZSwuEX
