我试图用C#画一个8x8的棋盘。这是我第一次尝试绘制它。它不会吸引董事会,我也找不到我失踪的东西。

     public void Form1_Load(object sender, EventArgs e)
     {
         Bitmap bm = new Bitmap(8 * 100, 8 * 100);
         Graphics g = Graphics.FromImage(bm);
         Color color1, color2;
         for (int i = 0; i < 8; i++)
         {
             if (i % 2 == 0)
             {
                 color1 = Color.Black;
                 color2 = Color.White;
             }
             else
             {
                 color1 = Color.White;
                 color2 = Color.Black;
             }
             SolidBrush blackBrush = new SolidBrush(color1);
             SolidBrush whiteBrush = new SolidBrush(color2);

             for (int j = 0; j < 8; j++)
             {
                 if (j % 2 == 0)
                     g.FillRectangle(blackBrush, i * 100, j * 100, 100, 100);
                 else
                     g.FillRectangle(whiteBrush, i * 100, j * 100, 100, 100);
             }
         }

         g.DrawImage(bm, 150, 200);
     }

BackgroundImage = bm;添加到代码的底部。

您正在绘制电路板,只是不显示位图......

编辑:我不确定你是否感兴趣,但我重写了这段代码。

Bitmap bm = new Bitmap(800, 800);
using (Graphics g = Graphics.FromImage(bm))
using (SolidBrush blackBrush = new SolidBrush(Color.Black))
using (SolidBrush whiteBrush = new SolidBrush(Color.White))
{
    for (int i = 0; i < 8; i++)
    {
        for (int j = 0; j < 8; j++)
        {
            if ((j % 2 == 0 && i % 2 == 0) || (j % 2 != 0 && i % 2 != 0))
                g.FillRectangle(blackBrush, i * 100, j * 100, 100, 100);
            else if ((j % 2 == 0 && i % 2 != 0) || (j % 2 != 0 && i % 2 == 0))
                g.FillRectangle(whiteBrush, i * 100, j * 100, 100, 100);
        }
    }
    BackgroundImage = bm;
}

        //Variables
        int rowSize = 8;
        int colSize = 8;
        //Calculation
        for (int row = 0; row < rowSize; row++) //Loop throw ROW's
        {
            for (int col = 0; col < colSize; col++) //Loop throw COL's
            {
                if ((row + col) % 2 == 0) //Check if cells is EVEN
                {
                    Console.Write("X"); //White square
                }
                else
                {
                    Console.Write("O"); //Black square
                }
            }
            Console.WriteLine(); //Switch to a new line

考虑将棋盘分解成行和列(水平和垂直)。通过for循环对第0至8行进行索引。列相同。对于每个正方形,请检查该行与该列的索引总和是否为“ par”(除以2的其余部分为0),则等于白色正方形。否则,它将分配一个黑色正方形。诀窍是((row + col)%2)。交替给出0或1的值。在“ for循环”列的每次迭代结束时,该行都会更改。

出于性能方面的考虑,您也可以跳过绘制其他彩色图块,而仅先用辅助色填充背景,然后迭代主要色图块。示例:

    public static class GridGenerator
    {
        public static void CreateGridBackground()
        {

            DrawingVisual visual = new DrawingVisual();
            DrawingContext context = visual.RenderOpen();
            context.DrawRectangle(Brushes.Red, null, new Rect(0, 0, 256, 512));
            for (int xRow = 0; xRow < 256 / 16; xRow++)
            {
                for (int yColumn = 0; yColumn < 512 / 16; yColumn++)
                {
                    if ((yColumn % 2 == 0 && xRow % 2 == 0) || (yColumn % 2 != 0 && xRow % 2 != 0))
                    {
                        context.DrawRectangle(Brushes.White, null, new Rect(xRow * 16, yColumn * 16, 16, 16));
                    }
                }
            }
            context.Close();

            RenderTargetBitmap bmp = new RenderTargetBitmap(256, 512, 96, 96, PixelFormats.Pbgra32);
            bmp.Render(visual);

            PngBitmapEncoder encoder = new PngBitmapEncoder();
            encoder.Frames.Add(BitmapFrame.Create(bmp));
            encoder.Save(new FileStream("C:/Users/Krythic/Desktop/Test.png", FileMode.Create));
        }
    }

理论上这要快50%(实际上没有进行基准测试,因此请随意将其视为虚数),因为您是通过填充一种颜色将图形切成两半,而不是将其实际绘制为单个图块。只是说接受或离开它。
