Question

好吧我有一个

        string[,] grid = new string[3, 3] {{" "," "," "},
                                           {" "," "," "},
                                           {" "," "," "}};

我有一个代码，我让用户以这种形式输入x和y的坐标（x，y（例如2,2）），我似乎有的问题是如何实际绘制实际数组中的符号/字符，我将如何在Main？

中进行处理

Answer 1

为了示例，我们假设您要在网格的右下角输入符号$。你这样做：

grid[2,2] = "$";

现在，如果你打印它，你的数组将会是这样的：

{{" "," "," "},
 {" "," "," "},
 {" "," ","$"}};

不要忘记数组是基于0的，所以在你的情况下没有3个插槽，只有0,1和2。

如果您想知道如何将该网格输出到控制台，请尝试：

    int rowLength = grid.GetLength(0);
    int colLength = grid.GetLength(1);

    for (int i = 0; i < rowLength; i++)
    {
        for (int j = 0; j < colLength; j++)
        {
            Console.Write(string.Format("{0} ", grid[i, j]));
        }
        Console.Write(Environment.NewLine + Environment.NewLine);
    }

编辑：您询问了如何获取用户的输入，然后将符号放在指定位置：

Console.WriteLine("Please enter the x-Coordinate");
int x = Console.ReadLine();
Console.WriteLine("Please enter the y-Coordinate");
int y = Console.ReadLine();

grid[x,y] = "$";

//then redraw the grid if you desire using the code above

Answer 2

这是你需要的吗？

for (int i = 0; i < grid.GetLength(0); i++)
{
    for (int j = 0; j < grid.GetLength(1); j++) Console.Write(grid[i, j]);
    Console.WriteLine()
}
