如何将sql查询结果填充到C# Datagridviewer中？

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

namespace YourNamespace
{
    public partial class YourForm : Form
    {
        private string connectionString = "YourConnectionString"; // 替换为实际的数据库连接字符串

        public YourForm()
        {
            InitializeComponent();
        }

        private void LoadData()
        {
            try
            {
                using (SqlConnection connection = new SqlConnection(connectionString))
                {
                    connection.Open();

                    string sqlQuery = "SELECT * FROM YourTable"; // 替换为实际的SQL查询语句

                    using (SqlCommand command = new SqlCommand(sqlQuery, connection))
                    {
                        using (SqlDataReader reader = command.ExecuteReader())
                        {
                            DataTable dataTable = new DataTable();
                            dataTable.Load(reader);

                            dataGridView.DataSource = dataTable;
                        }
                    }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show("Error: " + ex.Message);
            }
        }

        private void YourForm_Load(object sender, EventArgs e)
        {
            LoadData();
        }
    }
}
