使用代码实现九九乘法表C#

当然！以下是使用C#实现九九乘法表的代码：

using System;

class Program
{
    static void Main(string[] args)
    {
        for (int i = 1; i <= 9; i++)
        {
            for (int j = 1; j <= i; j++)
            {
                Console.Write($"{j} × {i} = {i * j}\t");
            }
            Console.WriteLine();
        }
    }
}

这段代码使用了两个嵌套的循环，外层循环控制乘法表的行数，内层循环控制每一行的列数。通过`Console.Write`语句输出每个乘法表达式，并使用制表符`\t`进行对齐。最后的`Console.WriteLine()`语句用于换行。

运行这段代码，你将得到如下输出：

1 × 1 = 1	
1 × 2 = 2	2 × 2 = 4	
1 × 3 = 3	2 × 3 = 6	3 × 3 = 9	
1 × 4 = 4	2 × 4 = 8	3 × 4 = 12	4 × 4 = 16	
1 × 5 = 5	2 × 5 = 10	3 × 5 = 15	4 × 5 = 20	5 × 5 = 25	
1 × 6 = 6	2 × 6 = 12	3 × 6 = 18	4 × 6 = 24	5 × 6 = 30	6 × 6 = 36	
1 × 7 = 7	2 × 7 = 14	3 × 7 = 21	4 × 7 = 28	5 × 7 = 35	6 × 7 = 42	7 × 7 = 49	
1 × 8 = 8	2 × 8 = 16	3 × 8 = 24	4 × 8 = 32	5 × 8 = 40	6 × 8 = 48	7 × 8 = 56	8 × 8 = 64	
1 × 9 = 9	2 × 9 = 18	3 × 9 = 27	4 × 9 = 36	5 × 9 = 45	6 × 9 = 54	7 × 9 = 63	8 × 9 = 72	9 × 9 = 81
