方法一:
Apperarance 属性:Faltbuttons
SizeMode属性:Fixed各个TabPage的Text :空
ItemSize : Width=0;Height=1;//Height好象不能设为0,但也就那么一丁点儿,不影响
方法二:
private void Form1_Load(object sender, EventArgs e)
{
tabControl1.Region = new Region(new RectangleF(this.tabPage1.Left, this.tabPage1.Top,
this.tabPage1.Width, this.tabPage1.Height));
}
