可能的重复：
如何在 C# 中对面板进行双缓冲？
用于绘制图形和滚动的 C# 面板

我在面板上绘制位图，我在同一面板上使用缩放。缩放时面板不断闪烁。为什么面板没有 DoubleBuffered 属性？

代码：

                Graphics g = Graphics.FromHwnd(panel.Handle);
                if (newImage == true)
                {
                    g.Clear(SystemColors.Control);
                    newImage = false;
                }

                g.DrawImage(bmp, hOffset, vOffset);
                g.Dispose();

c# panel for drawing graphics and scrolling

I draw a bitmap on a panel, i use zooming on the same panel. While zooming the panel is continuously flickering. Why do not panel have the DoubleBuffered property?

Code:

                Graphics g = Graphics.FromHwnd(panel.Handle);
                if (newImage == true)
                {
                    g.Clear(SystemColors.Control);
                    newImage = false;
                }

                g.DrawImage(bmp, hOffset, vOffset);
                g.Dispose();

在构造函数中添加此代码

this.SetStyle(ControlStyles.AllPaintingInWmPaint |ControlStyles.UserPaint |ControlStyles.DoubleBuffer, true);

Add this code inside the constructor

this.SetStyle(ControlStyles.AllPaintingInWmPaint |ControlStyles.UserPaint |ControlStyles.DoubleBuffer, true);

用这个。

System.Drawing.BufferedGraphics

我是一名游戏开发人员。在游戏中，我们首先在后缓冲区中绘制所有对象，然后将其复制或翻转到前缓冲区。您可以用作

System.Drawing.BufferedGraphics

后缓冲区并将其渲染为图形对象。

System.Drawing.Graphics

例如：

        System.Drawing.Graphics g = this.CreateGraphics();
        System.Drawing.BufferedGraphicsContext dc = new BufferedGraphicsContext();
        BufferedGraphics backbuffer = dc.Allocate(g, new Rectangle(new Point(0, 0), g.VisibleClipBounds.Size.ToSize()));
        backbuffer.Graphics.DrawImage(Image.FromFile(@"c:\test.jpg"), new Point(10, 10));
        backbuffer.Render(g);

use this.

System.Drawing.BufferedGraphics

I am a game developer.In games we first draw all objects in a backbuffer and then copy or flip it to frontbuffer.You can use

System.Drawing.BufferedGraphics

as backbuffer and render it to graphics object.

System.Drawing.Graphics

for example:

        System.Drawing.Graphics g = this.CreateGraphics();
        System.Drawing.BufferedGraphicsContext dc = new BufferedGraphicsContext();
        BufferedGraphics backbuffer = dc.Allocate(g, new Rectangle(new Point(0, 0), g.VisibleClipBounds.Size.ToSize()));
        backbuffer.Graphics.DrawImage(Image.FromFile(@"c:\test.jpg"), new Point(10, 10));
        backbuffer.Render(g);
