You can't, it is drawn with the color that the user selected in her preferred theme, selected in Control Panel's Display applet. Overriding the user preference is risky, but you can do so by drawing it yourself. Set the DGV's BorderStyle property to None and draw a border yourself in the form's OnPaintBackground() method. For example:
你不能，它是用用户在她的首选主题中选择的颜色绘制的，在控制面板的显示小程序中选择。覆盖用户偏好是有风险的，但您可以通过自己绘制来实现。将 DGV 的 BorderStyle 属性设置为 None 并在窗体的 OnPaintBackground() 方法中自己绘制边框。例如：
protected override void OnPaintBackground(PaintEventArgs e) {
base.OnPaintBackground(e);
Rectangle rc = new Rectangle(dataGridView1.Left - 1, dataGridView1.Top - 1,
dataGridView1.Size.Width + 1, dataGridView1.Size.Height + 1);
e.Graphics.DrawRectangle(Pens.Fuchsia, rc);
}
