As title says, I have access to the current listitem - and it's easy enough to get the author/created by name - but how do I retrieve the e-mail address of the author in C# from the object model?
Thanks.
You can get the SPUser from a SPFieldUserValue object:
SPFieldUserValue userValue =
new SPFieldUserValue(web, item[SPBuiltInFieldId.Author].ToString());
SPUser user = userValue.User;
string email = user.Email;
