Some recent experimental results on measurements of branching fraction of leptonic D(s)+ decays and semileptonic D decays, which were measured at the BaBar, Belle, BESIII and CLEO-c experiments in the last several years, are reviewed. The decay constants of D(s)+ mesons as well as form factors of D semileptonic decays are also briefly reviewed. In addition, the extraction of |V_cd| and |V_cs| based on these measurements are discussed. With the newly determined |V_cd| and |V_cs| based on these measurements together with other CKM matrix elements quoted from PDG2013 the unitarity of the CMK matrix are checked as well.
