组合排列的实现方法

　　最近在做数据分析系统，里面涉及到组合排列的问题，查找了很多的资料，但是感觉很多资料都是比较零散的，达不到项目需求。

后来经过一段的时间的探索，终于实现了组合排列的功能。下面我就来简单说说吧。

     需求描述:　　

　  要实现的功能就是字符或数字的组合排列。例如：ab 的所有组合为：ab,ba ；  ab的所有不重复排列为：ab。

其实这也是彩票中常说的直选和组选。效果图如下：

　　功能实现

　　这里就不多说了，直接贴上实现代码吧。

      1.窗体界面设计

         设计代码：

 1 partial class FrmDemo 2   { 3     /// <summary> 4     /// 必需的设计器变量。 5     /// </summary> 6     private System.ComponentModel.IContainer components = null; 7  8     /// <summary> 9     ///
