Answer 1

如果有人遇到同样的问题，这是对我有用的答案 Border TabControl

正如它所描述的，创建一个 NativeTabControl 对象并分配要删除其边框的 tabControl 的句柄。您可以将此 NativeTabControl 类用作窗体类中的内部类。您不必更改内部类中的任何内容。只需按照上述步骤操作即可。所有的功劳都应该归功于代码的原始设计者。我只是把它放在这里，供遇到同样问题并需要漂亮而性感的答案的任何人使用!

using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Windows.Forms;

public class Form1
{


public Form1()
{
    // This call is required by the Windows Form Designer.
    InitializeComponent();

    // Add any initialization after the InitializeComponent() call.
    this.NativeTabControl1 = new NativeTabControl();
    this.NativeTabControl2 = new NativeTabControl();
    this.NativeTabControl1.AssignHandle(this.TabControl1.Handle);
    this.NativeTabControl2.AssignHandle(this.TabControl2.Handle);
}

private NativeTabControl NativeTabControl1;

private NativeTabControl NativeTabControl2;
private class NativeTabControl : NativeWindow
{

    protected override void WndProc(ref Message m)
    {
        if ((m.Msg == TCM_ADJUSTRECT)) {
            RECT rc = (RECT)m.GetLParam(typeof(RECT));
            //Adjust these values to suit, dependant upon Appearance
            rc.Left -= 3;
            rc.Right += 3;
            rc.Top -= 3;
            rc.Bottom += 3;
            Marshal.StructureToPtr(rc, m.LParam, true);
        }
        base.WndProc(ref m);
    }

    private const Int32 TCM_FIRST = 0x1300;
    private const Int32 TCM_ADJUSTRECT = (TCM_FIRST + 40);
    private struct RECT
    {
        public Int32 Left;
        public Int32 Top;
        public Int32 Right;
        public Int32 Bottom;
    }

}
