這篇文章介紹了C#實(shí)現(xiàn)Array,List,Dictionary互相轉(zhuǎn)換的方法，文中通過(guò)示例代碼介紹的非常詳細(xì)。對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值，需要的朋友可以參考下

一、代碼實(shí)例實(shí)現(xiàn)功能

將Array轉(zhuǎn)換為L(zhǎng)ist
將List轉(zhuǎn)換為Array
將Array轉(zhuǎn)換為Dictionary
將Dictionary轉(zhuǎn)換為Array
將List轉(zhuǎn)換為Dictionary
將Dictionary轉(zhuǎn)換為L(zhǎng)ist

二、代碼實(shí)現(xiàn)

學(xué)生類(lèi)

    class Student
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Gender { get; set; }
    }
