Question

c#中怎么用foreach实现二维数组的显示输出??

请给个实例

Answer 1

如果是foreach的话，是一行一行输出
如下
int[,] numbers2D = new int[3, 2] { { 9, 99 }, { 3, 33 }, { 5, 55 } };

foreach (int i in numbers2D)
{
System.Console.Write("{0} ", i);
}
// Output: 9 99 3 33 5 55

Answer 2

foreach(var i1 in list1)
{
foreach(var i2 in i1)
{
Console.write(i2+'\t');
}
Console.Writeline("");
}
这样就行了吧

Answer 3

int[,] array = new int[4, 5];
for (int i = 0; i < array.GetLength(0); i++)
{
for (int j = 0; j < array.GetLength(1); j++)
{
Console.WriteLine("{0}\t", array[i, j]);
}
Console.WriteLine();
}

Answer 4

foreach嵌套

追问

能给个实例吗？
