How to get user account name?

Question

C++ / C#

How to get the user's name?
For example, the username is ivanov_ii, and the start menu says Ivanov Ivan Ivanovich, this is exactly what you need to get.
In Google they say that you need to use LDAP. However, I haven't seen any real examples.
There is this:

hr = ADsGetObject(L"LDAP://CN=computers,DC=mydomain,DC=local", IID_IADsContainer, (void**) &pCont );

In Borland C++ Builder 6.0 , I know that in VB6 it looks like this:
(void**) &pCont

Sub asdas()
Set SI_ = CreateObject("ADSystemInfo")
Set Un_ = GetObject("LDAP://" & SI_.UserName)
UZ_ = Un_.DisplayName
msgbox UZ_
End Sub

It returns the full name from the user account that is logged on to the domain. Not his login.
