核心提示: using System;class MyClass{static void Main(){int[,] arr = new int[3, 4];arr[0,0] = 11;arr[0,1] = 12;arr[0,2] = 13;arr[0,3] = 14;arr[1,0] = 21;ar


using System;

class MyClass
{
  static void Main()
  {
    int[,] arr = new int[3, 4];

    arr[0,0] = 11;
    arr[0,1] = 12;
    arr[0,2] = 13;
    arr[0,3] = 14;
    arr[1,0] = 21;
    arr[1,1] = 22;
    arr[1,2] = 23;
    arr[1,3] = 24;
    arr[2,0] = 31;
    arr[2,1] = 32;
    arr[2,2] = 33;
    arr[2,3] = 34;

    foreach (int i in arr) Console.WriteLine(i);

    Console.ReadKey();
  }
}

多维数组:


using System;

class MyClass
{
  static void Main()
  {
    int[,,] arr = new int[2, 3, 4];

    for (int x = 0; x < 2; x++) for (int y = 0; y < 3; y++) for (int z = 0; z < 4; z++)
      arr[x,y,z] = Convert.ToInt32(Convert.ToString(x+1) + Convert.ToString(y+1) + Convert.ToString(z+1));

    foreach (int i in arr) Console.WriteLine(i);

    Console.ReadKey();
  }
}

数组中的数组:


using System;

class MyClass
{
  static void Main()
  {
    int[][] arr = new int[3][];
    arr[0] = new int[2] { 11, 12 };
    arr[1] = new int[3] { 21, 22, 23 };
    arr[2] = new int[4] { 31, 32, 33, 34 };

    foreach (int[] ns in arr) foreach (int n in ns)
        Console.WriteLine(n);

    Console.ReadKey();
  }
}
