Using e+e- collisions recorded at the {psi}(3770) resonance with the CLEO-c detector at the Cornell Electron Storage Ring, we determine absolute hadronic branching fractions of charged and neutral D mesons. Among measurements for both Cabibbo-favored and Cabibbo-suppressed modes, we obtain reference branching fractions B(D0 {yields} K-{pi}+) = (3.91 {+-} 0.08 {+-} 0.09)% and B(D+ {yields} K-{pi}+{pi}+) = (9.5 {+-} 0.2 {+-} 0.3)%, where the uncertainties are statistical and systematic, respectively. Using a determination of the integrated luminosity, we also extract the e+e- {yields} DD-bar cross sections.
