数据结构通用算法(深拷贝+比较)

    public class CompareIgnoreAttribute : Attribute

                    }
                }
                else
                {
                    PropertyDescriptorCollection pdcs = TypeDescriptor.GetProperties(th1);
                    foreach (PropertyDescriptor pd in pdcs)
                    {
                        bool bIgnore = false;
                        // 检查是否有“比较忽略”属性，有则跳过检查
                        foreach (Attribute at in pd.Attributes)

                            {
                                bIgnore = true;
                                break;
                            }
                        }

                        if (!bIgnore)
                        {
                            object ob1 = pd.GetValue(th1);
                            object ob2 = pd.GetValue(th2);
                            if (!DataInfo.Equ(ob1, ob2))
                            {
                                return false;
                            }
                        }
                    }
                }
            }
            catch (Exception)
            {
                // 不应有异常
            }

            return true;
        }

        //以下的方法仅给子类使用
        public virtual DataInfo copy()
        {
            return DataInfo.copy(this) as DataInfo;
        }
        public virtual bool Equ(DataInfo th)
        {
            return DataInfo.Equ(this, th);
        }
    };

使用示例

    [Serializable] // 深拷贝需要
    public class Car : DataInfo
    {
        public string m_name;
        public string Name
        {
            get { return m_name; }
            set { m_name = value; }
        }

        //[CompareIgnore] 加在这边没用
        protected double m_price;
        [CompareIgnore]
        public double Price
        {
            get { return m_price; }
            set { m_price = value; }
        }

        public Car(string name, double price)
        {
            this.m_name = name;
            this.m_price = price;
        }
    }

 进行深拷贝

    class Program
    {
        static void Main(string[] args)
        {
            Car a = new Car("a", 199999.99);
            Car b = a.copy() as Car;
            Console.WriteLine("Name " + b.Name.ToString() + ";Price " + b.Price.ToString());
        }
    }

输出结果为：Name a;Price 199999.99

 进行比较

    class Program
    {
        static void Main(string[] args)
        {
            Car a = new Car("a", 99999.99);
            Car b = new Car("a", 199999.99);
            bool bSame = a.Equ(b);
            Console.WriteLine(bSame.ToString());
        }
    }

输出结果为：True
