日期格式设定 XD%GNZ

9.获取错误信息并到指定页面 y-uSpW
8^puC
不要使用Response.Redirect,而应该使用Server.Transfer tfdb9#&?
Z_4|L+i<{
e.g /pWKV>tjj
// in global.asax ;TL>{"z`x
protected void Application_Error(Object sender, EventArgs e) { 1oI2
if (Server.GetLastError() is HttpUnhandledException) 1nR\m+{
Server.Transfer("MyErrorPage.aspx"); "..I$R
M Al4g+es
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) `h~-
} q4SEvP}fLx
|qf ef&
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 m[nrr6 G"
