C#窗体运行代码是什么

listBox和comboBox添加SelectedIndexChanged事件，相互操作对方的SelectedIndex属性
代码如下，如需工程文件请站内短信发邮箱

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

namespace WindowsFormsApp7
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            comboBox1.SelectedIndex = listBox1.SelectedIndex;
        }

        private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            listBox1.SelectedIndex = comboBox1.SelectedIndex;
        }
    }
}

有帮助麻烦点下【采纳该答案】，谢谢~~

将所有控件的DataSource全部绑定同一个数据源，都不用去管事件就可以实现一个更改全部更改。。。

            DataTable dt = new DataTable();
            dt.Columns.Add("CHS");
            dt.Columns.Add("ENG");
        
            dt.Rows.Add("东", "East");
            dt.Rows.Add("南", "South");
            dt.Rows.Add("西", "West");
            dt.Rows.Add("北","North");

            this.comboBox1.DataSource = dt;
            this.listBox1.DataSource = dt;
            this.comboBox1.DisplayMember = "CHS";//显示中        
            this.listBox1.DisplayMember = "ENG";//显示英
