C# winform ListBox实现滚动条自动滚动至底部

效果如图：

 using System;
 using System.Collections.Generic;
 using System.ComponentModel;
 using System.Data;
 using System.Drawing;
 using System.Linq;
 using System.Text;
 using System.Threading;
 using System.Threading.Tasks;
 using System.Windows.Forms;

 namespace ListBoxAutoScroll
 {
     public partial class Form1 : Form
     {
         Thread[] threadArr = new Thread[];
         bool scroll = false;
         object obj = new object();
         delegate void AddItemCallback(string text);
         public Form1()
         {
             InitializeComponent();
         }

         private void btnStart_Click(object sender, EventArgs e)
         {
             listBoxMsg.Items.Clear();
             for (int i = ; i < threadArr.Length; i++)
             {
                 if (threadArr[i] == null || threadArr[i].ThreadState == ThreadState.Aborted || threadArr[i].ThreadState == ThreadState.Stopped)
                 {
                     threadArr[i] = new Thread(new ThreadStart(() => AddData(i)));
                     threadArr[i].Name = i.ToString();
                 }
                 threadArr[i].Start();
             }
         }
         public void AddData(int i)
         {

             while (true)
             {
                 AddItem("ListBox中添加【第" + i.ToString() + "项】");
                 Thread.Sleep();
             }
         }
         private void AddItem(string text)
         {
             if (this.listBoxMsg.TopIndex == this.listBoxMsg.Items.Count - (int)(this.listBoxMsg.Height / this.listBoxMsg.ItemHeight))
                 scroll = true;
             if (this.listBoxMsg.InvokeRequired)
             {
                 AddItemCallback d = new AddItemCallback(AddItem);
                 this.Invoke(d, new object[] { text });
             }
             else
             {
                 this.listBoxMsg.Items.Add(text);
             }
             if (scroll)
                 this.listBoxMsg.TopIndex = this.listBoxMsg.Items.Count - (int)(this.listBoxMsg.Height / this.listBoxMsg.ItemHeight);
         }

         private void btnStop_Click(object sender, EventArgs e)
         {
             for (int i = ; i < threadArr.Length; i++)
             {
                 if (threadArr[i] != null && threadArr[i].ThreadState != ThreadState.Stopped && threadArr[i].ThreadState != ThreadState.Aborted)
                 {
                     threadArr[i].Abort();
                 }
             }
         }
     }
 }
