We present a theoretical study on the de Haas-van Alphen (dHvA) oscillation in the vortex state of type-II superconductors, with a special focus on the connection between the gap anisotropy and the oscillation damping. Numerical calculations for three different gap structures clearly indicate that the average gap along the extremal orbit is relevant for the magnitude of the extra damping, thereby providing support for experimental efforts to probe gap anisotropy through the dHvA signal. We also derive an analytic formula for the extra damping which will be useful to estimate angle- and/or band-dependent gap amplitudes.
