A search for narrow resonances at high mass in the dimuon and dielectron channels has been performed by the CMS experiment at the CERN LHC, using pp collision data recorded at sqrt{s}=7 TeV. The event samples correspond to an integrated luminosity of 1.1 fb^{-1}. Heavy dilepton resonances are predicted in theoretical models with extra gauge bosons (Z') or as Kaluza-Klein graviton excitations (G_{KK}) in the Randall-Sundrum model. Upper limits on the inclusive cross section of Z'(G_{KK}) to l+l- relative to Z to l+l- are presented. These limits exclude at 95 % confidence level a Z' with standard-model-like couplings below 1940 GeV, the superstring-inspired Z_{psi} below 1620 GeV, and, for values of the coupling parameter k/M_{Pl} of 0.05 (0.1), Kaluza--Klein gravitons below 1450 (1780)GeV.
