如何将TextBox控件绑定到StringBuilder实例？

using System;
using System.Text;
using System.Windows.Forms;

namespace StringBuilderBindingExample
{
    public partial class Form1 : Form
    {
        private StringBuilder _stringBuilder;
        private bool _isUpdating;

        public Form1()
        {
            InitializeComponent();
            _stringBuilder = new StringBuilder();
            textBox1.TextChanged += TextBox1_TextChanged;
        }

        private void TextBox1_TextChanged(object sender, EventArgs e)
        {
            if (!_isUpdating)
            {
                _stringBuilder.Clear();
                _stringBuilder.Append(textBox1.Text);
            }
        }

        private void UpdateTextBox()
        {
            _isUpdating = true;
            textBox1.Text = _stringBuilder.ToString();
            _isUpdating = false;
        }

        private void SomeMethodThatUpdatesStringBuilder()
        {
            // Example method that updates the StringBuilder
            _stringBuilder.Append(" New text");
            UpdateTextBox();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            // Simulate an update to the StringBuilder
            SomeMethodThatUpdatesStringBuilder();
        }
    }
}
