一个关于C#数组的问题
using System;using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace P3_4
{
class Program
{
static void Main()
{
int[,] x = new int[2, 3] { { 1, 2, 3 }, { 3, 5, 8 } };
int[,] y = new int[,] { { 10, 50 }, { 25, 75 }, { 50, 150 }, { 100, 80 } };
int[, ,] z = { { { 1, 2 }, { 3, 5 }, { 8, 13 } }, { { 1, 2 }, { 3, 5 }, { 8, 13 } } };
Console.Write("数组x的长度为：");
Console.WriteLine(x.Length);
Console.WriteLine("各维长度：{0} * {1}", x.GetLength(0), x.GetLength(1));
Console.Write("数组y的长度为：");
Console.WriteLine(y.Length);
Console.WriteLine("各维长度：{0} * {1}", y.GetLength(0), y.GetLength(1));
Console.Write("数组z的长度为：");
Console.WriteLine(z.Length);
Console.WriteLine("各维长度：{0} * {1} * {2}", z.GetLength(0), z.GetLength(1),z.GetLength (2));
}
}
}
为什么x,y数组后面需要 new int[, ]，而z数组后面不需要呢？？？
