dt,Z^z+"E protected void Application_Error(Object sender, EventArgs e) {
YzQ1c~+ if (Server.GetLastError() is HttpUnhandledException)
-fmJkI Server.Transfer("MyErrorPage.aspx");
kaB4[u G$MEVfd" //其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :)
D\9-/p }
\3^ue0 {.jW"0U 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
