在WinForm的`TabControl`中，没有直接将标签在顶部且靠右显示的属性设置。不过可以利用自定义绘画的方式来实现此效果。思路是先把控件的`DrawMode`设置为`OwnerDrawFixed`，然后处理`DrawItem`事件重新绘制标签的位置。 以下是示例代码： ```csharp using System; using System.Drawing; using System.Windows.Forms; namespace TabControlRightAlignTop { public partial class Form1 : Form { public Form1() { InitializeComponent(); tabControl1.DrawMode = TabDrawMode.OwnerDrawFixed; tabControl1.DrawItem += TabControl1_DrawItem; } private void TabControl1_DrawItem(object sender, DrawItemEventArgs e) { TabControl tabControl = (TabControl)sender; TabPage tabPage = tabControl.TabPages[e.Index]; Rectangle bounds = tabControl.GetTabRect(e.Index); // 计算新的绘制位置，让标签靠右 int newX = tabControl.Width - bounds.Width - 5; // 5 是右边距 bounds.X = newX; // 绘制标签背景 using (Brush backBrush = new SolidBrush(e.State == DrawItemState.Selected ? SystemColors.Highlight : tabControl.BackColor)) { e.Graphics.FillRectangle(backBrush, bounds); } // 绘制标签文本 TextRenderer.DrawText(e.Graphics, tabPage.Text, tabPage.Font, bounds, tabPage.ForeColor, TextFormatFlags.VerticalCenter | TextFormatFlags.Right); // 如果是选中的标签，绘制一个边框 if (e.State == DrawItemState.Selected) { Rectangle borderRect = new Rectangle(bounds.X, bounds.Y, bounds.Width, bounds.Height - 1); e.Graphics.DrawRectangle(Pens.Black, borderRect); } } } } ```
