c# 我如何在消息框(控制台应用程序)中显示此数组

Question

谁能帮我用一个消息框在两列中显示随机数和正方形，每列都有一个标签？

    const int NUM_ROWS = 10;
    const int NUM_COLS = 2;

        int[,] randint = new int [NUM_ROWS,NUM_COLS];
        Random randNum = new Random();

        for (int row = 0; row < randint.GetLength(0); row++)
        {
            randint[row,0] = randNum.Next(1,100);
            randint[row,1] = randint[row,0]*randint[row,0];

        Console.Write(string.Format("{0,5:d} {1,5:d}\n", randint[row,0], randint[row,1]));

我通过将 System.Windows.Forms 的引用添加到我的控制台应用程序来实现它，并获得了您想要的结果。这是我的代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace ConsoleApplication6
{
    class Program
    {
        static void Main(string[] args)
        {
            const int NUM_ROWS = 10;
            const int NUM_COLS = 2;

            int[,] randint = new int[NUM_ROWS, NUM_COLS];
            Random randNum = new Random();

            for (int row = 0; row < randint.GetLength(0); row++)
            {
                randint[row, 0] = randNum.Next(1, 100);
                randint[row, 1] = randint[row, 0] * randint[row, 0];

                Console.Write(string.Format("{0,5:d} {1,5:d}\n", randint[row, 0], randint[row, 1]));

                MessageBox.Show(string.Format("{0,5:d} {1,5:d}\n", randint[row, 0], randint[row, 1]));
                Console.ReadKey();
            }
        }
    }
}  

我的输出:
此外，虽然这不是要求，但以防万一添加对 System.Windows.Form 的引用，请右键单击解决方案资源管理器中的引用并选择 .Net 选项卡，然后在选择所需的 dll 后按确定。干杯!
