新手求教，输出一个9*9的数组

番茄暴走123 发布于 2016-03-08 17:11， 4385 次点击
static void Main(string[] args)
        {
            string[,] array = new string[9, 9];
            for (int i = 0; i < 9; i++)
            {
                for (int j = 0; j < 9; j++)
                {
                    array[i, j] = ".";
                    Console.Write(array[i, j]);
                }
                Console.ReadLine();

            }

请教，输出的9*9数组，只显示了一行，必须手动打个回车才能输出下一行。百度了一下，\r\n可以用，可是改成 Console.ReadLine("\r\n")，程序总出错，为啥子呢

因为你有 Console.ReadLine();这一行代码，所以每输出一行需要打一下回车，把这个删除就好了

还是不对呢，怎模办
 static void Main(string[] args)
        {
            string[,] array = new string[9, 9];
            for (int i = 0; i < 9; i++)
            {
                for (int j = 0; j < 9; j++)
                {
                    array[i, j] = ".";
                    Console.Write(array[i, j]);
                }
                Console.Write('\n');      
            }
                        // this is for get input, which will stop the screen
        }

string[,] array = new string[9, 9];
            for (int i = 0; i < 9; i++)
            {
                for (int j = 0; j < 9; j++)
                {
                    array[i, j] = ".";
                    Console.Write(array[i, j]);

                Console.WriteLine();
            }
            Console.ReadLine();

你这个程序要实现什么，感觉一点用都没有，错误一大堆，建议再学习吧。参考下下面的看看。
程序代码：
class Program
{   
    public void GeneratePointMatrix( )
    {
        int k=0;
        for(int i=0;i<9;i++)
        {
            for(int j=0;j<9;j++)
            {
                k=i*j;
                Console.Write(k.ToString()+"  ");
            }
            Console.WriteLine();
        }
    }  
      
    static void Main(string[] args)
    {
        GeneratePointMatrix();
        
        Console.ReadKey();
    }
}

谢谢版主，就是想输出一个9×9数组，赋值都是"."。

int.Parse  是将string 类型转换成 int ，如果string 为null 或者无法转换，就会报错。
你的Value 开始就是null ,用 int.Parse当然会报错

我想不明白你怎么想的，感觉你一点都不会C#。
程序代码：
public string Value=".";

public void GeneratePointMatrix(int x, int y)
{
    for (int m=1;m<=x;m++)
    {
        for (int n=1;n<=y;n++)
        {
            Console.Write(Value+"  ");
        }
        Console.WriteLine();
    }
}  

static void Main(string[] args)
{
    int i=9,j=9;
    GeneratePointMatrix(i,j);
    Console.WriteLine();
    Console.ReadKey();
}

是的，确实不懂，谢谢您的指教。可是，我用您的代码输进去后，怎么还是出现两个错误呢？
