We perform the first search for lepton-number-violating B{sup +}{yields}D{sup -}l{sup +}l{sup '+} decays, where l and l{sup '} stand for e or {mu}, using 772x10{sup 6} BB pairs accumulated at the {Upsilon}(4S) resonance with the Belle detector at the KEKB e{sup +}e{sup -} collider. No evidence for these decays has been found. Assuming uniform three-body phase space distributions for the D{sup -}l{sup +}l{sup '+} decays, we set the following upper limits on the branching fractions at 90% confidence level: B(B{sup +}{yields}D{sup -}e{sup +}e{sup +})<2.6x10{sup -6}, B(B{sup +}{yields}D{sup -}e{sup +}{mu}{sup +})<1.8x10{sup -6} and B(B{sup +}{yields}D{sup -}{mu}{sup +}{mu}{sup +})<1.1x10{sup -6}.
