c# - 克隆的目的是什么？

Question

我是 C# 新手，正在处理现有项目。我clone在所有数据类中都发现了这个，有人能告诉我为什么有必要这样做吗？如果我不使用克隆，有任何已知问题吗？提前致谢！

public class PreviewRequestDetails : ICloneable
    {

    [DataMember]
    public string Address { get; set; }

    ........


     public object Clone()
        {
            return new PreviewRequestDetails
            {
                Address = this.Address,
                Email = this.Email,
                Id = this.Id,
                Country = this.Country,
                Phone = this.Phone,
                Titles = this.Titles.Select(p => p.Clone() as Title).ToList(),
                CreatedBy = this.CreatedBy,
                CreatedOn = this.CreatedOn,
                UpdatedOn = this.UpdatedOn,
                Delete = this.Delete
            };
        }
}
