编辑：

是的，我已经试过了。

panel1.doublebuffered不存在，只有this.doublebuffered。而且我也不需要缓冲的形式，只是面板。

panel1.doublebuffered does not exist, only this.doublebuffered. And I don't need to buffer the Form, just the Panel.

推荐答案

您需要从面板或图片框派生。

You need to derive from Panel or PictureBox.

有分歧这取决于您选择如何启用缓冲。

There are ramifications to this depending on how you choose to enable the buffering.

如果您设置this.DoubleBuffer标志，那么你应该没问题。

If you set the this.DoubleBuffer flag then you should be ok.

如果您手动更新的样式，那么你必须自己画的形式WM_PAINT。

If you manually update the styles then you have to paint the form yourself in WM_PAINT.

如果你真的觉得雄心勃勃可以保持并绘制自己的后台缓冲区为位图。

If you really feel ambitious you can maintain and draw your own back buffer as a Bitmap.

using System.Windows.Forms;

public class MyDisplay : Panel
{
    public MyDisplay()
    {
        this.DoubleBuffered = true;

        // or

        SetStyle(ControlStyles.AllPaintingInWmPaint, true);
        SetStyle(ControlStyles.OptimizedDoubleBuffer, true);
        UpdateStyles();
    }
}
