在C#中使用getBytes()从SQL获取数据(提供了JAVA代码)

using System;
using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        string connectionString = "Data Source=YourServerName;Initial Catalog=YourDatabaseName;User ID=YourUsername;Password=YourPassword";
        string query = "SELECT * FROM YourTableName";

        using (SqlConnection connection = new SqlConnection(connectionString))
        {
            SqlCommand command = new SqlCommand(query, connection);
            connection.Open();

            SqlDataReader reader = command.ExecuteReader();

            while (reader.Read())
            {
                // 获取数据的方法取决于你的表结构和数据类型
                int id = reader.GetInt32(0);
                string name = reader.GetString(1);
                // 其他列...

                Console.WriteLine($"ID: {id}, Name: {name}");
            }

            reader.Close();
        }
    }
}
