如果第一次没有找到任何C#，我如何正确地多次查询数据库中的值

using System;
using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        string connectionString = "YourConnectionString"; // 替换为你的数据库连接字符串

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

            bool found = false;
            int attempts = 0;

            while (!found && attempts < 3) // 最多尝试3次查询
            {
                string query = "SELECT * FROM YourTable WHERE Language = 'C#'"; // 替换为你的查询语句

                using (SqlCommand command = new SqlCommand(query, connection))
                {
                    using (SqlDataReader reader = command.ExecuteReader())
                    {
                        if (reader.HasRows)
                        {
                            found = true;

                            while (reader.Read())
                            {
                                // 处理查询结果
                                string value = reader.GetString(0);
                                Console.WriteLine(value);
                            }
                        }
                    }
                }

                attempts++;
            }

            if (!found)
            {
                Console.WriteLine("未找到任何C#的值。");
            }
        }
    }
}
