假设您的行位于一个名为myPanel的面板中，那么您需要以下方法：

private void MyPanel_MouseMove(object sender, MouseEventArgs e)
{
    if (IsShapeContainingMouse(e.Location))
    {
        Cursor = System.Windows.Forms.Cursors.Hand;
    }
    else
    {
        Cursor = System.Windows.Forms.Cursors.Default;
    }
}

private bool IsShapeContainingMouse(Point location)
{
    Point shapeStartPosition = GetShapeStartPosition();
    Point shapeEndPosition = GetShapeEndPosition();
    return shapeStartPosition.X <= location.X && location.X <= shapeEndPosition.X && shapeStartPosition.Y <= location.Y && location.Y <= shapeEndPosition.Y;
 }
}

您需要实现GetShapeStartPosition()和GetShapeStartPosition()两个方法来获取行的开始和结束。
