PCB 合拼遍历(全排序+旋转90度) 基本遍历方法

//准备数据
            List<RectSizeDemo> RectSizeList = new List<RectSizeDemo>(); RectSizeList.Add(new RectSizeDemo() { Name = "A板" }); RectSizeList.Add(new RectSizeDemo() { Name = "B板" }); RectSizeList.Add(new RectSizeDemo() { Name = "C板" }); //3款板 全排序组合总类 1*2*3=6 //3款板 旋转90度组合总类 2*2*2=8 //3款板 总排样组合 6*8=48种组合 //计算 PCB旋转90度组合总类
            int PowCount = (int)Math.Pow(2, RectSizeList.Count()) - 1; //执行PCB 合拼遍历(全排序+旋转90度)
            RectSizeDemo.Loop(RectSizeList, PowCount, 0, RectSizeList.Count - 1);
