日期格式设定

9.获取错误信息并到指定页面 L>nO:`>h
#v8Cy|I
不要使用Response.Redirect,而应该使用Server.Transfer 60PYCqWc
BX$hAQ(6Q
e.g `Cj,HI_/*
// in global.asax ryEvmWYu
protected void Application_Error(Object sender, EventArgs e) { t<lyg0f
if (Server.GetLastError() is HttpUnhandledException) 5Rs?CVVb
Server.Transfer("MyErrorPage.aspx"); $FCw$ +w
^Kw(&v
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) /=M.-MU2
} v MWC(m
"k>bUe|RG
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 ~&~C#yjg1
