如何在windows服务中执行SQL命令？

using System;
using System.Data.SqlClient;

namespace WindowsServiceExample
{
    public class DatabaseService
    {
        private string connectionString = "Data Source=YourServer;Initial Catalog=YourDatabase;User ID=YourUsername;Password=YourPassword";

        public void ExecuteSqlCommand(string sqlQuery)
        {
            using (SqlConnection connection = new SqlConnection(connectionString))
            {
                connection.Open();
                using (SqlCommand command = new SqlCommand(sqlQuery, connection))
                {
                    command.ExecuteNonQuery();
                }
            }
        }
    }
}

using System.ServiceProcess;

namespace WindowsServiceExample
{
    public partial class MyService : ServiceBase
    {
        private DatabaseService databaseService;

        public MyService()
        {
            InitializeComponent();
            databaseService = new DatabaseService();
        }

        protected override void OnStart(string[] args)
        {
            // 在此处执行SQL命令
            string sqlQuery = "INSERT INTO TableName (Column1, Column2) VALUES ('Value1', 'Value2')";
            databaseService.ExecuteSqlCommand(sqlQuery);
        }

        protected override void OnStop()
        {
            // 停止服务时的清理逻辑
        }
    }
}
