Electron affinity and electronegativity ....
No. They are not the same thing.
Electronegativity is not something which can be measured directly, but is calculated in terms of other measurements. Electronegativity was popularized by Linus Pauling. Pauling computed electronegativity using bond energies. Electronegativity is a measure of the attraction an atom has for shared pairs of electrons.
Electron affinity is the energy given off when a mole of gaseous atoms gains a mole of electrons to form a mole of -1 charged ions.
Neither should be confused with the first ionization energy which is the energy required to remove a mole of electrons from a mole of neutral gaseous atoms to form the +1 charged ions.
The Mulliken electronegativity scale is calculated using the ionization energy and the electron affinity.

Related, but not the same thing.

No. Just look at the definitions of the 2 terms.
