隱式類型轉換

代碼如下：

 

        class a
        {
                public int i
                {
                        get;
                        private set;
                }

                public a(int i)
                {
                        this.i = i;
                }

                public static implicit operator a(int i)
                {
                        return new a(i);
                }

                public static implicit operator int(a _a)
                {
                        return _a.i;
                }
        }

 

需保證兩點：

     1、不會發生轉化信息丟失

     2、不會引發異常

好處：

操作簡單，可讀性增強？。。。。

 

使用：

 

                static void Main(string[] args)
                {
                        a a1 = 1;
                        int i = a1;
                }
