using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        string connectionString = "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;";

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

                // 设置命令超时时间为 5 秒
                SqlCommand command = new SqlCommand("SELECT * FROM myTable", connection);
                command.CommandTimeout = 5;

                using (SqlDataReader reader = command.ExecuteReader())
                {
                    while (reader.Read())
                    {
                        // 处理查询结果
                    }
                }
            }
            catch (SqlException ex)
            {
                // 捕获超时异常
                if (ex.Number == -2)
                {
                    Console.WriteLine("查询超时：" + ex.Message);
                }
                else
