Using 0.8x10{sup 6} D{sup +}D{sup -} pairs collected with the CLEO-c detector at the {psi}(3770) resonance, we have searched for flavor-changing neutral current and lepton-number-violating decays of D{sup +} mesons to final states with dielectrons. We find no indication of either, obtaining 90% confidence level upper limits of B(D{sup +}{yields}{pi}{sup +}e{sup +}e{sup -})<7.4x10{sup -6}, B(D{sup +}{yields}{pi}{sup -}e{sup +}e{sup +})<3.6x10{sup -6}, B(D{sup +}{yields}K{sup +}e{sup +}e{sup -})<6.2x10{sup -6}, and B(D{sup +}{yields}K{sup -}e{sup +}e{sup +})<4.5x10{sup -6}.
