日期格式设定 Ic0Y

9.获取错误信息并到指定页面 Gs,:$Im

不要使用Response.Redirect,而应该使用Server.Transfer F^75y?

if (Server.GetLastError() is HttpUnhandledException) ,KW

Server.Transfer("MyErrorPage.aspx"); 9qB0F_xl

//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) `x9Eo4(/
} USz~l7Xs

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 g"evnp
