 程序代码：int count; foreach(int[,] aa in ar) { count = 0; foreach(int bb in aa) { count++; Console.Out.Write(bb.ToString()+" "); if(count %4==0) Console.WriteLine(); } Console.WriteLine(); } |
Random ra=new Random ();
int[,] a = new int[3, 4];
int[,] b = new int[3, 4];
int[,] c = new int[3, 4];
ArrayList ar=new ArrayList() ;
for(int i=0;i<3;i++)
{
for(int j=0;j<4;j++)
{
a[i, j] = ra.Next(10, 100);
}
}
ar.Add(a);
for (int i = 0; i < 3; i++)
{
for (int j = 0; j < 4; j++)
{
b[i, j] = ra.Next(10, 100);
}
}
ar.Add(b);
for (int i = 0; i < 3; i++)
{
for (int j = 0; j < 4; j++)
{
c[i, j] = ra.Next(10, 100);
}
}
ar.Add(c);
//ar 里加入了三个二维数组，怎样把它们一一取出。
