C# Winform：如何设置 TabControl（不是标签页）的基色

using System.Drawing;
using System.Windows.Forms;

namespace YourNamespace
{
    public partial class YourForm : Form
    {
        public YourForm()
        {
            InitializeComponent();
            SetTabControlColors(tabControl1, Color.LightBlue, Color.Black);
        }

        private void SetTabControlColors(TabControl tabControl, Color backgroundColor, Color foregroundColor)
        {
            tabControl.BackColor = backgroundColor;
            tabControl.ForeColor = foregroundColor;

            foreach (TabPage tabPage in tabControl.TabPages)
            {
                tabPage.BackColor = backgroundColor;
                tabPage.ForeColor = foregroundColor;
            }
        }
    }
}
