如何获取3x3矩阵的输入 [英] How to I get the input for 3x3 matrix

问题描述

我被要求获得矩阵输入。

我是通过逐行获取输入来实现的。



如



1

2

3

4

5

6

7

8

9



但我被要求以矩阵格式输入



1（空格）2（空格）3

4 （空格）5（空格）6

7（空格）8（空格）9



有没有解决办法。

I was asked to get the matrix input.
I did it by getting the input line by line.

Such as

1
2
3
4
5
6
7
8
9

But I was asked to get the input as in matrix format

1(Space)2(Space)3
4(Space)5(Space)6
7(Space)8(Space)9

Is there any solution to do so.

推荐答案

试试这个

Try this

Console.WriteLine("input:3*3 matrics. number space number space number space enter");
       int[,] input = new int[3, 3];
       for (int i = 0; i < 3; i++)
       {
           for (int j = 0; j < 3; j++)
           {
               var key = Console.ReadKey();
               if (key.Key != ConsoleKey.Spacebar &&  key.Key != ConsoleKey.Enter)
                   input[i, j] = Convert.ToInt32(key.KeyChar.ToString());
               else
                   j--;
               if (key.Key == ConsoleKey.Enter)
                   Console.WriteLine();
           }
       }
       Console.WriteLine();
       Console.WriteLine("output");
       for (int i = 0; i < 3; i++)
       {

           for (int j = 0; j < 3; j++)
           {
               Console.Write(input[i,j] + " ");
           }
           Console.WriteLine( );
       }
