如何从Visual Studio将图像插入数据库

I have a database table PHOTOS created in Visual studio. It has id (int), filename (string) and photo filed type image. I made a form to insert current immage from PictureBox into database. Of course, since I am very inexperienced it does not work. How do you insert image into database from picturebox in c#? Thank you for answer, I know this code is wrong but I hope it gives you an idea what am I trying to do.I have a database table PHOTOS created in Visua
