C#中序列化和反序列化

Question

   private void button5_Click(object sender, EventArgs e)
        {
            SaveFileDialog test = new SaveFileDialog();
            test.Filter = "二进制文件(.bin)| *.bin";
            Worker wor = new Worker();
            wor.ID = textBoxID.Text;
            wor.Name = textBoxName.Text;
            wor.Sex = comboBoxSex.SelectedItem.ToString();
            wor.Bitrhday = dateTimePickerBirthday.Text.ToString();
            wor.Constellation = (Constellations)Enum.Parse(typeof(Constellations), comboBoxConstellation.SelectedItem.ToString());
            wor.Result = listBoxInfo.Text;
             
            IFormatter formatter = new BinaryFormatter();
            
            DialogResult res = test.ShowDialog();
            if (res == DialogResult.OK)
            {
                Stream stream = new FileStream(test.FileName, FileMode.Create, FileAccess.Write);
                formatter.Serialize(stream, wor);
               
            }        }        private void button7_Click(object sender, EventArgs e)
        {
            OpenFileDialog open = new OpenFileDialog();
            open.Filter = "二进制文件(.bin)| *.bin";
            ArrayList worklist = new ArrayList();
            Worker wor = new Worker();
            wor.ID = textBoxID.Text;
            wor.Name = textBoxName.Text;
            wor.Sex = comboBoxSex.SelectedItem.ToString();
            wor.Bitrhday = dateTimePickerBirthday.Text.ToString();
            wor.Constellation = (Constellations)Enum.Parse(typeof(Constellations), comboBoxConstellation.SelectedItem.ToString());
            worklist.Add(wor);
            IFormatter formatter = new BinaryFormatter();
            Stream stream = new FileStream(open.FileName, FileMode.Open, FileAccess.Read); 
            DialogResult res=open.ShowDialog();
            ArrayList loadlist = (ArrayList)formatter.Deserialize(stream);
            if (res == DialogResult.OK)
            {
                loadlist.Add(wor);
               
              
                
            }
             
        }想要让一个listbox中显示序列化的内容  控件中包括导入（反序列化）导出（序列化），
谢谢各位帮忙了
