Question

我一直在寻找这个解决方案很长一段时间，在这里，或其他指导网站..但是很多人想要改变进度条的前景色（随着进度而上升的部分）

我想，我的小图片可以说出一切：

现在，我正在使用此代码绘制自定义栏，您可以在上面看到。是否可以将后台编辑代码组合到我的构造函数代码中？

 public class NewProgressBar : ProgressBar
{
    public NewProgressBar()
    {
        this.SetStyle(ControlStyles.UserPaint, true);

    }

    protected override void OnPaintBackground(PaintEventArgs pevent)
    {
        // None... Helps control the flicker.
    }

    protected override void OnPaint(PaintEventArgs e)
    {
        const int inset = 0; // A single inset value to control teh sizing of the inner rect.

        using (Image offscreenImage = new Bitmap(this.Width, this.Height))
        {
            using (Graphics offscreen = Graphics.FromImage(offscreenImage))
            {


                Rectangle rect = new Rectangle(0, 0, this.Width, this.Height);


                if (ProgressBarRenderer.IsSupported)
                    ProgressBarRenderer.DrawHorizontalBar(offscreen, rect);

                rect.Inflate(new Size(-inset, -inset)); // Deflate inner rect.
                rect.Width = (int)(rect.Width * ((double)this.Value / this.Maximum));
                if (rect.Width == 0) rect.Width = 1; // Can't draw rec with width of 0.
                TextureBrush mybrush = new TextureBrush(Properties.Resources.loading);
                LinearGradientBrush brush = new LinearGradientBrush(rect, Color.DarkGoldenrod, Color.Gold, LinearGradientMode.Vertical);
                offscreen.FillRectangle(mybrush, inset, inset, rect.Width, rect.Height);

                e.Graphics.DrawImage(offscreenImage, 0, 0);
                offscreenImage.Dispose();
            }
        }
    }
}
