如何使用c#检索存储在sql server中的多媒体？

using System;
using System.Data.SqlClient;
using System.Drawing;
using System.IO;

class Program
{
    static void Main()
    {
        string connectionString = "your_connection_string";
        string query = "SELECT ImageData FROM Images WHERE ImageId = @ImageId";

        using (SqlConnection connection = new SqlConnection(connectionString))
        {
            using (SqlCommand command = new SqlCommand(query, connection))
            {
                command.Parameters.AddWithValue("@ImageId", 1);

                connection.Open();
                byte[] imageData = (byte[])command.ExecuteScalar();

                // 将二进制数据加载到内存中
                using (MemoryStream stream = new MemoryStream(imageData))
                {
                    // 使用System.Drawing命名空间中的类进行处理和显示
                    Image image = Image.FromStream(stream);
                    image.Save("image.jpg"); // 保存图片到本地
                    image.Dispose();
                }
            }
        }
    }
}
