String name;
Name = request. querystring ["emailname"];
　　
Try
{
Int A = Name. indexof ("@", 0, name. Length );
F_user.value = Name. substring (0, );
F_domain.value = Name. substring (a + 1, name. Length-(A + 1 ));
F_pass.value = request. querystring ["psw"];
}
　　
Catch
{
Script. Alert ("wrong email! ");
Server. Transfer ("index. aspx ");
}
