另一种样式的螺旋数组输出

static void Main(string[] args) { Console.Write("请输入正整数："); int n = int.Parse(Console.ReadLine()); //读取输入 Console.WriteLine(); int[,] arr = GetSpiralMatrix(n); //输出矩阵 for (int i = 0; i < n; i++) { for (int j = 0; j < n; j++) { Console.Write(arr[j, i]); Console.Write("\t"); //对齐 } Console.Write("\n"); } Console.ReadKey(); } /// <summary> /// 获取螺旋矩阵输出的方法 /// </summary> static int[,] GetSpiralMatrix(int row) { int[,] intArr = new int[row, row]; int x = 0, y = 0; //初始坐标 int m = 1; //初始圈数 string type = "R"; //初始方向为右 for (int i = 1; i <= row * row; i++) { intArr[x, y] = i; //初始值 switch (type) { case "R": //向右 x++; if (y == 0) { type = "D"; m++; break; } if (i == m * m - m) { type = "U"; break; } break; case "D": //向下 y++; if (x == 0) { type = "R"; m++; break;} if (i == m * m - m) { type = "L"; break;} break; case "L": //向左 x--; if (i == m * m - 1) { type = "D"; break; } break; case "U": //向上 y--; if (i == m * m - 1) { type = "R"; break; } break; } } return intArr; }
