聽(tīng)說(shuō)讀寫(xiě)

 //范例一  在兩個(gè)對(duì)象直接拷貝屬性
            ClassA target = new ClassA();
            ClassB source = new ClassB() { A = "AA", B = 2, C = DateTime.Now };

            //復(fù)制代碼
            CopyHelper<ClassB, ClassA>.Copy(source, target);//這一句是調(diào)用方法

            Console.WriteLine(target.A);
            Console.WriteLine(target.B);
            Console.WriteLine(target.C);

    public sealed class ClassA
    {

        public string A { get; set; }
        public int B { get; set; }
        public string Title { get; set; }
        public int Id { get; set; }
        public DateTime C { get; set; }

    }
    public sealed class ClassB

        public string A { get; set; }

        public DateTime C { get; set; }
    }
