解决方案

为了更改选项卡的背景颜色，将TabControl的DrawMode设置为OwnerDraw，然后处理DrawItem事件以进行绘制. "C#"> // 设置绘制模式并订阅DrawItem事件 此 .tabControl1.DrawMode = System.Windows.Forms.TabDrawMode.OwnerDrawFixed;

 私有 无效 tabControl1_DrawItem(对象发​​件人，System.Windows.Forms.DrawItemEventArgs e)
        {
            字体f;
            刷回来刷;
            刷前刷；

            如果(例如e.Index ==  this  .tabControl1.SelectedIndex)
            {
                f = 新 Font(例如，Font，FontStyle.Italic | FontStyle.Bold)；
                backBrush = 新 System.Drawing.Drawing2D.LinearGradientBrush(例如，Bounds，Color.Blue，Color.Red，System.Drawing.Drawing2D.LinearGradientMode.BackwardDiagonal)；
                foreBrush = Brushes.PowderBlue;
            }
            其他
            {
                f = e.字体
                backBrush = 新 SolidBrush(e.BackColor);
                foreBrush = 新 SolidBrush(e.ForeColor);
            }

            字符串 tabName = 此 .tabControl1.TabPages [e.Index] .Text;
            StringFormat sf = 新 StringFormat();
            sf.Alignment = StringAlignment.Center;
            e.Graphics.FillRectangle(backBrush，e.Bounds);
            矩形r = e.Bounds;
            r = 新 Rectangle(rX，rY +  3 ，r.Width，r.Height- 3 )；
            e.Graphics.DrawString(tabName，f，foreBrush，r，sf);

            sf.Dispose();
            如果(例如e.Index ==  this  .tabControl1.SelectedIndex)
            {
                f.Dispose();
                backBrush.Dispose();
            }
            其他
            {
                backBrush.Dispose();
                foreBrush.Dispose();
            }
        }

解决方案

Inorder to change background color of tabs,set the TabControl''s DrawMode to OwnerDraw, and then handle the DrawItem event to draw.

//set the drawmode and subscribe to the DrawItem event
this.tabControl1.DrawMode = System.Windows.Forms.TabDrawMode.OwnerDrawFixed;

private void tabControl1_DrawItem(object sender, System.Windows.Forms.DrawItemEventArgs e)
        {
            Font f;
            Brush backBrush;
            Brush foreBrush;

            if(e.Index == this.tabControl1.SelectedIndex)
            {
                f = new Font(e.Font, FontStyle.Italic | FontStyle.Bold);
                backBrush = new System.Drawing.Drawing2D.LinearGradientBrush(e.Bounds, Color.Blue, Color.Red, System.Drawing.Drawing2D.LinearGradientMode.BackwardDiagonal);
                foreBrush = Brushes.PowderBlue;
            }
            else
            {
                f = e.Font;
                backBrush = new SolidBrush(e.BackColor);
                foreBrush = new SolidBrush(e.ForeColor);
            }

            string tabName = this.tabControl1.TabPages[e.Index].Text;
            StringFormat sf = new StringFormat();
            sf.Alignment = StringAlignment.Center;
            e.Graphics.FillRectangle(backBrush, e.Bounds);
            Rectangle r = e.Bounds;
            r = new Rectangle(r.X, r.Y + 3, r.Width, r.Height - 3);
            e.Graphics.DrawString(tabName, f, foreBrush, r, sf);

            sf.Dispose();
            if(e.Index == this.tabControl1.SelectedIndex)
            {
                f.Dispose();
                backBrush.Dispose();
            }
            else
            {
                backBrush.Dispose();
                foreBrush.Dispose();
            }
        }
