如何使用c# visual Studio将查询放到列表中？

using System;
using System.Data;
using System.Data.SqlClient;
using System.Windows.Forms;

namespace QueryToList
{
    public partial class Form1 : Form
    {
        private string connectionString = "Data Source=YourServer;Initial Catalog=YourDatabase;User ID=YourUsername;Password=YourPassword";

        public Form1()
        {
            InitializeComponent();
        }

        private void btnQuery_Click(object sender, EventArgs e)
        {
            try
            {
                // 创建数据库连接
                using (SqlConnection connection = new SqlConnection(connectionString))
                {
                    connection.Open();

                    // 创建查询命令
                    using (SqlCommand command = new SqlCommand("SELECT * FROM YourTable", connection))
                    {
                        // 执行查询并获取结果
                        SqlDataAdapter adapter = new SqlDataAdapter(command);
                        DataTable dataTable = new DataTable();
                        adapter.Fill(dataTable);

                        // 将结果绑定到DataGridView控件
                        dataGridView1.DataSource = dataTable;
                    }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show("查询出错：" + ex.Message);
            }
        }
    }
}
