c# 如何将一个list集合隐式转换为另一个list集合

没转化之前: 

public class ShopSpecialTimeExtParams
{
    public int ShopId { get; set; }
    public List<SpecialTimeExtItem> TimeExts { get; set; }
}

public class SpecialTimeExtItem
{
    public string SpecialStartDate { get; set; }
    public string SpecialEndDate { get; set; }
    public string SpecialStartTime { get; set; }
    public string SpecialEndTime { get; set; }
    public int PromiseTimeChange { get; set; }
}

ShopSpecialTimeExtParams = new ShopSpecialTimeExtParams()
{
    ShopId = shopSpecialTimeExt.ShopId,
    TimeExts = shopSpecialTimeExt.TimeExts 无法隐式转换

},

 使用 Select进行处理转换

ShopSpecialTimeExtParams = new ShopSpecialTimeExtParams()
{
    ShopId = shopSpecialTimeExt.ShopId,
    TimeExts = shopSpecialTimeExt.TimeExts.Select(n => new SpecialTimeExtItem()
    {
        SpecialStartDate = n.SpecialStartDate,
        SpecialEndDate = n.SpecialEndDate,
        SpecialStartTime = n.SpecialStartTime,
        SpecialEndTime = n.SpecialEndTime,
        PromiseTimeChange = n.PromiseTimeChange
    }).ToList()

}
