Question

我不断画框，我需要表格不要闪烁。我该如何做到这一点？

public partial class Form1 : Form
{
    Image[] dude = new Image[3];
    static int renderpoint = 0;
    int lastimage = 0;

    public Form1()
    {
        dude[1] = new Bitmap(@"snipe1.bmp");
        dude[0] = new Bitmap(@"snipe0.bmp");

        InitializeComponent();
    }

    private void Form1_Shown(object sender, EventArgs e)
    {
        MainLoop();
    }

    private void MainLoop()
    {
        double FPS = 10;

        long ticks1 = 0;
        long ticks2 = 0;
        double interval = (double)Stopwatch.Frequency / FPS;

        while (true)
        {
            ticks2 = Stopwatch.GetTimestamp();
            if (ticks2 >= ticks1 + interval)
            {
                ticks1 = Stopwatch.GetTimestamp();

                MoveGraphics();
                this.Refresh(); 
            }

            Thread.Sleep(1); 
        }
    }

    private void Form1_Paint(object sender, PaintEventArgs e)
    {
        Graphics g = e.Graphics;
        Rectangle rect = new Rectangle(renderpoint, 0, 100, 100);
        Color lowcolor = Color.FromArgb(0, 128, 64);
        Color highcolor = Color.FromArgb(0, 128, 64);

        ImageAttributes imageAttr = new ImageAttributes();
        imageAttr.SetColorKey(lowcolor, highcolor);

        if (lastimage == 1)
        {
            lastimage = 0;
            g.DrawImage(dude[1], rect, 0, 0, 100, 100, GraphicsUnit.Pixel, imageAttr);
        }
        else
        {
            lastimage = 1;
            g.DrawImage(dude[0], rect, 0, 0, 100, 100, GraphicsUnit.Pixel, imageAttr);
        }  
    }

    void MoveGraphics()
    {
        if (renderpoint > 950)
        {
            renderpoint = 0;
        }
        else
        {
            renderpoint += 10;
        }
    }
}

目前的代码。建议？

Answer 1

将其粘贴到Form1构造函数中：

this.DoubleBuffered = true;

Answer 2

在Paint事件处理程序
禁用自动删除背景。
通过样式或手动启用双缓冲。
如果要重新粉饰，请致电Invalidate

如果您想尝试平滑动画，那么我是否可以建议您跳转到WPF，OpenGL或XNA。 GDI +不是为动画设计的（Windows消息循环不是实时系统，所以你总是会有抖动）。
