【C#】小知识 #4 : 转换关键字来做出繁体中文int

情境:

常使用阿拉伯数字1234567890
但想要有一天在写code时
输入int i = 1234567890
自动帮你转成一二三四五六七八九零

这时候可以使用[explicit,implicict] + operator 转换关键字来实作功能

举例:

void Main(){int_zh_tw  obj_test = 1234567890;Console.WriteLine(obj_test.Value);}class int_zh_tw{public string Value { get; set; }public static implicit operator int_zh_tw(int inValue){var str_int = inValue.ToString().Replace("1","一").Replace("2","二").Replace("3","三").Replace("4","四").Replace("5","五").Replace("6","六").Replace("7","七").Replace("8","八").Replace("9","九").Replace("0","零");return new int_zh_tw() { Value = str_int };}}
