其它这次的这个控件的改变并是太大，只是从选中与不选中，和图标上下了一些功夫。
大家先看一下效果吧



这个图片上没有图标，是可以直接设置的这个大家等下下载一下我的源代码，可以自己设置一下。

public partial class CTabControl : System.Windows.Forms.TabControl
通过上面一行代码我们可以看到这个控件是继承Windows的TabContrl而来的，这也就是说Windows自带的控件所具有的功能在这里都会自动继承而来。
我们先来看看 DrawControl(Graphics g)方法。

internal void DrawControl(Graphics g)

{

if (!Visible)

return;

//Rectangle TabControlArea = new Rectangle(2, 2, this.Width - 3, this.Height - 2);

Rectangle TabControlArea = this.ClientRectangle;

Rectangle TabArea = new Rectangle(3, 24, this.ClientRectangle.Width - 7, this.ClientRectangle.Height - 28);// this.DisplayRectangle;

//----------------------------

// 控件内部颜色

Brush br = new SolidBrush(Color.Transparent);

g.FillRectangle(br, TabControlArea);

br.Dispose();

//----------------------------

//----------------------------

// draw border

int nDelta = SystemInformation.Border3DSize.Width;

//默认的控件边框颜色

Pen border = new Pen(SkinHelp.Defalutborder);

g.DrawRectangle(border, TabArea);

border.Dispose();

//----------------------------

//----------------------------

// clip region for drawing tabs

Region rsaved = g.Clip;

Rectangle rreg;

int nWidth = TabArea.Width + nMargin;

if (bUpDown)

{

// exclude updown control for painting

if (Win32.IsWindowVisible(scUpDown.Handle))

{

Rectangle rupdown = new Rectangle();

Win32.GetWindowRect(scUpDown.Handle, ref rupdown);

Rectangle rupdown2 = this.RectangleToClient(rupdown);

nWidth = rupdown2.X;

}

}

rreg = new Rectangle(TabArea.Left, TabControlArea.Top, nWidth - nMargin, TabControlArea.Height);

g.SetClip(rreg);

// draw tabs

for (int i = 0; i < this.TabCount; i++)

DrawTab(g, this.TabPages[i], i);

g.Clip = rsaved;

//----------------------------

//yuterz

//----------------------------

// draw background to cover flat border areas

if (this.SelectedTab != null)

{

TabPage tabPage = this.SelectedTab;

Color color = tabPage.BackColor;

//border = new Pen(color);

border = new Pen(Color.Green);

TabArea.Offset(1, 1);

TabArea.Width -= 2;

TabArea.Height -= 2;

//g.DrawRectangle(border, TabArea);

TabArea.Width -= 1;

TabArea.Height -= 1;

// g.DrawRectangle(border, TabArea);

border.Dispose();

}

//----------------------------

}

在这里我设置了默认的背景色和边框的颜色
当然大家也要吧自己设置
只要修改相应代码就行了，看注释就明白了。
这些完成了我们再来看看绘制Tab的事件

internal void DrawTab(Graphics g, TabPage tabPage, int nIndex)

{

Rectangle recBounds = this.GetTabRect(nIndex);

RectangleF tabTextArea = (RectangleF)this.GetTabRect(nIndex);

bool bSelected = (this.SelectedIndex == nIndex);

Point[] pt = new Point[7];

if (this.Alignment == TabAlignment.Top)

{

pt[0] = new Point(recBounds.Left, recBounds.Bottom);

pt[1] = new Point(recBounds.Left, recBounds.Top + 3);

pt[2] = new Point(recBounds.Left + 3, recBounds.Top);

pt[3] = new Point(recBounds.Right - 3, recBounds.Top);

pt[4] = new Point(recBounds.Right, recBounds.Top + 3);

pt[5] = new Point(recBounds.Right, recBounds.Bottom);

pt[6] = new Point(recBounds.Left, recBounds.Bottom);

}

else

{

pt[0] = new Point(recBounds.Left, recBounds.Top);

pt[1] = new Point(recBounds.Right, recBounds.Top);

pt[2] = new Point(recBounds.Right, recBounds.Bottom - 3);

pt[3] = new Point(recBounds.Right - 3, recBounds.Bottom);

pt[4] = new Point(recBounds.Left + 3, recBounds.Bottom);

pt[5] = new Point(recBounds.Left, recBounds.Bottom - 3);

pt[6] = new Point(recBounds.Left, recBounds.Top);

}

//----------------------------

// fill this tab with background color

//Brush br = new SolidBrush(tabPage.BackColor);

Brush br = new SolidBrush(Color.White);

//----------------------------

//----------------------------

// draw border

//g.DrawRectangle(SystemPens.ControlDark, recBounds);

// g.DrawPolygon(SystemPens.ControlDark, pt);

//默认的左右边框没有被选中时的标题边框颜色

g.DrawPolygon(new Pen(SkinHelp.ControlBorderBackColor), pt);

if (bSelected)

{

//----------------------------

// clear bottom lines

Pen pen = new Pen(tabPage.BackColor);

switch (this.Alignment)

{

case TabAlignment.Top:

g.DrawLine(pen, recBounds.Left + 1, recBounds.Bottom, recBounds.Right - 1, recBounds.Bottom);

g.DrawLine(pen, recBounds.Left + 1, recBounds.Bottom + 1, recBounds.Right - 1, recBounds.Bottom + 1);

break;

case TabAlignment.Bottom:

g.DrawLine(pen, recBounds.Left + 1, recBounds.Top, recBounds.Right - 1, recBounds.Top);

g.DrawLine(pen, recBounds.Left + 1, recBounds.Top - 1, recBounds.Right - 1, recBounds.Top - 1);

g.DrawLine(pen, recBounds.Left + 1, recBounds.Top - 2, recBounds.Right - 1, recBounds.Top - 2);

break;

}

g.FillPolygon(br, pt);

br.Dispose();

//左右被选中时颜色

g.DrawPolygon(new Pen(Color.Red), pt);

g.DrawLine(new Pen(Color.White, 2f), recBounds.Left + 1, recBounds.Bottom + 1, recBounds.Right - 1, recBounds.Bottom + 1);

pen.Dispose();

//----------------------------

}

else

{

//没有选中时的下边框颜色

g.DrawLine(new Pen(SkinHelp.ControlBorderBackColor), recBounds.Left + 1, recBounds.Bottom, recBounds.Right - 1, recBounds.Bottom);

}

if ((tabPage.ImageIndex >= 0) && (ImageList != null) && (ImageList.Images[tabPage.ImageIndex] != null))

{

int nLeftMargin = 8;

int nRightMargin = 2;

Image img = ImageList.Images[tabPage.ImageIndex];

Rectangle rimage = new Rectangle(recBounds.X + nLeftMargin, recBounds.Y + 1, img.Width, img.Height);

// adjust rectangles

float nAdj = (float)(nLeftMargin + img.Width + nRightMargin);

rimage.Y += (recBounds.Height - img.Height) / 2;

tabTextArea.X += nAdj;

tabTextArea.Width -= nAdj;

// draw icon

g.DrawImage(img, rimage);

}

// draw string

StringFormat stringFormat = new StringFormat();

stringFormat.Alignment = StringAlignment.Center;

stringFormat.LineAlignment = StringAlignment.Center;

br = new SolidBrush(SkinHelp.FontColor);

g.DrawString(tabPage.Text, Font, br, tabTextArea, stringFormat);

if (nIndex == 0)

{

//最左上角标题上的竖线

Pen pen = new Pen(SkinHelp.ControlBorderBackColor);

g.DrawLine(pen, 3, 5, 3, recBounds.Height + 3);

}

}

在这里主要是给左右没有选中，和选中时的标题加颜色。还有就是最左上角地那条线的颜色。大家可以根据我们代码进行修改，
找到适应自己软件或者是自己喜欢的颜色进行配置。我这里是用一个红色来代替，这样主要是为了色差大，容易区分。
接下来我们还要对上面的ICON进行处理处理访求 如下

internal void DrawIcons(Graphics g)

{

if ((leftRightImages == null) || (leftRightImages.Images.Count != 4))

return;

// calc positions

Rectangle TabControlArea = this.ClientRectangle;

Rectangle r0 = new Rectangle();

Win32.GetClientRect(scUpDown.Handle, ref r0);

// 当Tab多时背景颜色

Brush br = new SolidBrush(Color.Transparent);

g.FillRectangle(br, r0);

br.Dispose();

//当Tab多时边框颜色

Pen border = new Pen(SkinHelp.ControlBorderBackColor);

Rectangle rborder = new Rectangle(1, 1, 36, 19);

rborder.Inflate(-1, -1);

g.DrawRectangle(border, rborder);

border.Dispose();

int nMiddle = (r0.Width / 2);

int nTop = (r0.Height - 16) / 2;

int nLeft = (nMiddle - 16) / 2;

Rectangle r1 = new Rectangle(nLeft, nTop, 16, 16);

Rectangle r2 = new Rectangle(nMiddle + nLeft, nTop, 16, 16);

// draw buttons

Image img = leftRightImages.Images[1];

if (img != null)

{

if (this.TabCount > 0)

{

Rectangle r3 = this.GetTabRect(0);

if (r3.Left < TabControlArea.Left)

g.DrawImage(img, r1);

else

{

img = leftRightImages.Images[3];

if (img != null)

g.DrawImage(img, r1);

}

}

}

img = leftRightImages.Images[0];

if (img != null)

{

if (this.TabCount > 0)

{

Rectangle r3 = this.GetTabRect(this.TabCount - 1);

if (r3.Right > (TabControlArea.Width - r0.Width))

g.DrawImage(img, r2);

else

{

img = leftRightImages.Images[2];

if (img != null)

g.DrawImage(img, r2);

}

}

}

方法很简单主要是处理一下不同图标放上去的效果。会根据图标的不同而适应不同的效果。
感觉这个控件的语言可表达性不强主要是看代码，我把这个类的相关代码放上来大家看看，多多交流，多提保定意见。
