日期格式设定 rg{|/ ;imT

9.获取错误信息并到指定页面 2q,> *B?
FZ^j|2.L*
不要使用Response.Redirect,而应该使用Server.Transfer T?'Vb

e.g CN, oH4IU
// in global.asax )I`Ma6bX
protected void Application_Error(Object sender, EventArgs e) { ',P E25Z
if (Server.GetLastError() is HttpUnhandledException) {expx<+4F
Server.Transfer("MyErrorPage.aspx"); l gzA) (
\,5OPSB
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) f/6,b&l,
} (5(TbyWwD
1y($h<
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 KWH l+pL
