借助绑定控件实现数据选择录入

        private DataTable dt;
        private DataColumn dc;
        private DataColumn dc1;

        private void Form1_Load(object sender, EventArgs e)
        {
            dt = new DataTable();
            dc = new DataColumn("book");
            dc1 = new DataColumn("author");

            dt.Columns.Add(dc);
            dt.Columns.Add(dc1);

            dt.Rows.Add("西游记", "吴承恩");
            dt.Rows.Add("水浒传", "施耐庵");
            dt.Rows.Add("红楼梦", "曹雪芹");
            dt.Rows.Add("三国演义", "罗贯中");
            
            listBox1.DataSource=dt;
            listBox1.DisplayMember="book";
            listBox1.ValueMember = "author";
        }

        private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            if (listBox1.SelectedItem.ToString() != null)
            {
                textBox1.Text = ((DataRowView)listBox1.SelectedItem).Row[dc].ToString();
                textBox2.Text = ((DataRowView)listBox1.SelectedItem).Row[dc1].ToString();
            }
        }
