Question

in my following code i want to return data the null if my PictureBox(pbspic) is null else if PictureBox(pbspic) contains a picture I want data to return picture byte so that I can save null or picture in my database

using (MemoryStream stream = new MemoryStream())
        {
            Bitmap bmp = new Bitmap(pbspic.Image);
            bmp.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);
            stream.Position = 0;
            byte[] data = new byte[stream.Length];
            stream.Read(data, 0, data.Length);
            return data;
        }
cmd.Parameters.Add("@Photo", SqlDbType.VarChar).Value = data;
dm2.ExecActQuery("StudentsInsert", cmd);

Answer 1

try creating a metthod of your stream and then call it for picture like this

private byte[] GetPic(Image img)
    {
        using (MemoryStream stream = new MemoryStream())
        {
            Bitmap bmp = new Bitmap(pbspic.Image);
            bmp.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);
            stream.Position = 0;
            byte[] data = new byte[stream.Length];
            stream.Read(data, 0, data.Length);
            return data;
        }
    }

USAGE:

if (pbspic.Image == null)
        {
            cmd.Parameters.Add("@Photo", SqlDbType.VarChar).Value = "NULL";
        }
        else
        {
            cmd.Parameters.Add("@Photo", SqlDbType.Image).Value = GetPic(pbspic.Image);
        }
        dm2.ExecActQuery("StudentsInsert", cmd);
