如何在不提及图片URL的情况下将图片保存在图片框的SQL图像类型列中？

Question

I have a picturebox where custom image is drawn when mouse button is pressed now i want to save that image in SQL's image type column .

You could probably use this solution . Tho you would have to save the picturebox image to a jpeg first.

byte[] image = File.ReadAllBytes("D:\\11.jpg");

Edited:

    //without saving the image to a physical file
    MemoryStream stream=new MemoryStream();

pictureBox1.Image.Save(stream,System.Drawing.Imaging.ImageFormat.Jpeg);

byte[] pic=stream.ToArray(); 


SqlCommand sqlCommand = new SqlCommand("INSERT INTO imageTest (pic_id, pic) VALUES (1, @Image)", yourConnectionReference);
sqlCommand.Parameters.AddWithValue("@Image", image);
sqlCommand.ExecuteNonQuery();
