日期格式设定 rge/jE,^~Z

9.获取错误信息并到指定页面 r "R\
D~:fn|/Brp
不要使用Response.Redirect,而应该使用Server.Transfer s-B\8&^C

e.g 8h97~$7)
// in global.asax Jk*MxlA.b
protected void Application_Error(Object sender, EventArgs e) { 9':$!Eoq
if (Server.GetLastError() is HttpUnhandledException) 25L{bcng
Server.Transfer("MyErrorPage.aspx"); KX`,7-

//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) |.A>0-']M
} ?H&p zY~H
`O/)q^m1L
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 L/I-(08!Y:
