How to get current member in a Razor macro - macros

Question

I have asked this question on the Our Umbraco forums, however I wanted to also increase my chances of getting a solution by posting the same question here.
The issue I have is that, inside a Razor macro, I'm unable to get the current Member who is accessing the site. I have tried the following methods:
Calling Member.GetCurrentMember(), but this returns NULL.
Calling Membership.GetUser(), but this returns NULL
Calling UmbracoEnsuredPage.CurrentUser returned NULL;
Is there another way to get the current Member seeing how the above methods do not work in my case?

Answer 1

var m = Membership.GetUser();
That should work, just verified it myself on 4.7.1; it will return NULL if you are not logged in as a member, but when you log in it should get you what you want.

Answer 2

Just a slight change from #E.J.Brennan if the NULL is an issue you can check if you are logged on before trying to GetUser():
if (umbraco.library.IsLoggedOn())
{
m = Membership.GetUser();
}

Answer 3

Starting from v7 you can use the MembershipHelper
#Members.CurrentUserName
#Members.GetCurrentMember()
#Members.GetCurrentMemberId()

Answer 4

Now it's even easier, in the surfaceController you can use just one line:
var member = ApplicationContext.Current.Services.MemberService.GetById(Members.GetCurrentMemberId());
If Members MembershipHElper isn't accessible:
var memberShipHelper = new MembershipHelper(UmbracoContext.Current);
var member = ApplicationContext.Current.Services.MemberService.GetById(memberShipHelper.GetCurrentMemberId());
