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();

谢谢

学习 了

继续求教，这个数组如果用函数的方式写的话，怎么写呢

class Program
    {
        public void GeneratePointMatrix(int x, int y,string Value)
        {
            for (int i=0;i<9;i++)
            {
                for (int j=0;j<9;j++)
                {
                    int x=int.Parse(Value);
                    int y=int.Parse(Value);
                }
            }
        }  
       static void Main(string[],args)
       {
           GeneratePointMatrix();
           String Value=".";
           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。

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"."。
