如何去掉menu下的那条白线? 是否能改变menu的背景色

Question

你可以重画一个菜单,参考如下的代码段:protected override void OnDrawItem(System.Windows.Forms.DrawItemEventArgs e)
{
e.DrawBackground();
e.Graphics.FillRectangle(new System.Drawing.SolidBrush(e.BackColor),e.Bounds.Left,e.Bounds.Top,e.Bounds.Width-1,e.Bounds.Height-1);
if (this.m_Icon!=null)
{
e.Graphics.DrawIcon(this.m_Icon,new System.Drawing.Rectangle(e.Bounds.Left+2,e.Bounds.Top+(e.Bounds.Height-this.m_Font.Height)/2,16,16));
}
e.Graphics.DrawString(this.Text,this.m_Font,new System.Drawing.SolidBrush(e.ForeColor),e.Bounds.Left+20,e.Bounds.Top+(e.Bounds.Height-this.m_Font.Height)/2);
base.OnDrawItem (e);
}protected override void OnMeasureItem(System.Windows.Forms.MeasureItemEventArgs e)
{
e.ItemHeight=this.m_ReferrenceHeight;
e.ItemWidth=this.m_ReferrenceWidth;
base.OnMeasureItem (e);
}
