迭代式返回 IEnumerable<T>

private IEnumerable<PoliceForceViewModel> CreateResultList(IEnumerable<GPSData> gpsData)
        {
            foreach (var gpd in gpsData)
            {
                yield return new PoliceForceViewModel()
                {
                    //Text = gpd.PoliceType == GPSDataConstant.PoliceType_A
                    //? gpd.CarNo : gpd.PoliceId,
                    IsSelected = false,
                    Text = gpd.CarNo,
                    RelativeData = gpd
                };
            }
        }
