8.关于日期格式 ?yy,3:
D'<'"kUd
日期格式设定 =U,mzY(
DataFormatString="{0:yyyy-MM-dd}" WWG+0jQ9

9.获取错误信息并到指定页面 R/Z
zmb{
P9jPdls
不要使用Response.Redirect,而应该使用Server.Transfer ]oxi~TwY^
|ZtNCB5{^j
e.g *I9O+/,
// in global.asax Ri;_
8v[H|
protected void Application_Error(Object sender, EventArgs e) { W.Z`kH *B
if (Server.GetLastError() is HttpUnhandledException) _kT{W]
Server.Transfer("MyErrorPage.aspx"); X}B]0z>
AH?4F"
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 4}F~h
} y7|
3]>Z
qB5.of[N!
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 RZP7h>y6@
