1. 打开新的窗口并传送参数: b+7!$

日期格式设定 {|{}]B

9.获取错误信息并到指定页面 8(GH.)I+0

不要使用Response.Redirect,而应该使用Server.Transfer #1>DV@^F
q(N2#di
e.g :j sa.X
// in global.asax F4=+xd >0
protected void Application_Error(Object sender, EventArgs e) { vXdz?
if (Server.GetLastError() is HttpUnhandledException) m-{t%[Y
Server.Transfer("MyErrorPage.aspx"); s`:>"1\|
j\,HquTR
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 37#|X*L
} ah82S)a`}
=N_7DT
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 $6&P 69<
