你会在这里找到答案：Hide vertical scroll bar in ListBox control

基本上，您无法隐藏它。如果需要，您只能使其始终显示或自动显示。否则，您可能需要制作自定义控件来执行您想要的操作。

该链接还向您展示了如何创建一个类库来执行此操作（直接取自链接）：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace ClassLibrary1
{
    public class MyListBox : System.Windows.Forms.ListBox
    {
        private bool mShowScroll;
        protected override System.Windows.Forms.CreateParams CreateParams
        {
            get
            {
                CreateParams cp = base.CreateParams;
                if (!mShowScroll)
                    cp.Style = cp.Style & ~0x200000;
                return cp;
            }
        }
        public bool ShowScrollbar
        {
            get { return mShowScroll; }
            set
            {
                if (value == mShowScroll)
                    return;
                mShowScroll = value;
                if (Handle != IntPtr.Zero)
                    RecreateHandle();
            }
        }
    }    
}
