We report the results of a search for flavor-changing neutral current, lepton-flavor violating, and lepton-number violating decays of D⁺, D_s⁺, and D⁰ mesons (and their antiparticles) into modes containing muons and electrons. Using data from Fermilab charm hadroproduction experiment E791, we examine the πℓℓ and Kℓℓ decay modes of D⁺ and D_S⁺ and the ℓ⁺ℓ^- decay modes of D⁰. No evidence for any of these decays is found. Therefore, we present branching-fraction upper limits at 90% confidence level for the 24 decay modes examined. Eight of these modes have no previously reported limits, and fourteen are reported with significant improvements over previously published results.
