實現字元或數字的組合排列。例如：ab 的所有組合為： ab,ba ；ab的所有不重覆排列為：ab ...
最近在做數據分析系統，裡面涉及到組合排列的問題，查找了很多的資料，但是感覺很多資料都是比較零散的，達不到項目需求。
後來經過一段的時間的探索，終於實現了組合排列的功能。下麵我就來簡單說說吧。
需求描述:
要實現的功能就是字元或數字的組合排列。例如：ab 的所有組合為：ab,ba ； ab的所有不重覆排列為：ab。
其實這也是彩票中常說的直選和組選。效果圖如下：
功能實現
這裡就不多說了，直接貼上實現代碼吧。

2.添加引用
在項目中，添加引用——>AoTu.ZhuHe.dll
3.窗體類代碼
