c# 可变二维数组

Here, the task is to declare a two dimensional array – where number rows are given and columns are variable length:

在这里，任务是声明一个二维数组-其中给出了行数，列数是可变长度 ：

To declare such array, we use the following syntax:

为了声明这样的数组，我们使用以下语法：

    int[][] jag = new int[3][];

To assign rows values with variable length, we use following syntax:

要分配具有可变长度的行值，我们使用以下语法：

    jag[0] = new int[] { 12, 34, 5, 6, 7 };
jag[1] = new int[] { 15, 52 };
jag[2] = new int[] { 1, 2, 3 };

Program:

程序：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Array3
{
class Program
{
static void Main(string[] args)
{
int[][] jag = new int[3][];
jag[0] = new int[] { 12, 34, 5, 6, 7 };
jag[1] = new int[] { 15, 52 };
jag[2] = new int[] { 1, 2, 3 };
for(int i=0;i<3;i++)
{
for(int j=0;j<jag[i].Length;j++)
{
Console.Write("{0}\t", jag[i][j]);
}
Console.WriteLine();
}
Console.ReadKey();
}
}
}

Output

输出量

12      34      5       6       7
15      52
1       2       3
