如何在不改变外观的情况下禁用.net Winforms控件？

control.Enabled = false;

textBox.ReadOnly = true;

Image disabledImage = ControlPaint.DrawImageDisabled(Image.FromFile("path/to/image.png"), 0);
control.BackgroundImage = disabledImage;

public class CustomDisabledControl : OriginalControl
{
    protected override void OnPaint(PaintEventArgs e)
    {
        using (var brush = new SolidBrush(this.BackColor))
        {
            e.Graphics.FillRectangle(brush, this.ClientRectangle);
        }

        // 在此处添加自定义绘制代码，例如使用禁用的颜色绘制文本。
    }
}
