Answer 1

Here is Code to solve this issue.

          Byte[] img;
        con.Open();
        OracleCommand command = new OracleCommand("Select Image as BLOBDATA FROM tbltestImage ", con);
        command.InitialLONGFetchSize = -1;
        OracleDataReader rdr = command.ExecuteReader();

        DataTable dt = new DataTable();
        dt.Load(rdr);
        con.Close();
         if (dt.Rows.Count > 0)
        {

            if (dt.Rows[0]["BLOBDATA"].ToString() != "")
            {

                img = (Byte[])dt.Rows[0]["BLOBDATA"];


                MemoryStream ms = new MemoryStream(img);

                Bitmap bitmap = new Bitmap(ms);

                pictureBox2.Image = bitmap;

                pictureBox2.SizeMode = PictureBoxSizeMode.StretchImage;
            }
