        {
            try
            {
                string strFilePath = FupStudent.PostedFile.FileName;
                string strFileName = Path.GetFileName(strFilePath);
                string strExtension = Path.GetExtension(strFileName);
                string strContentType = strExtension;
                switch (strExtension)
                {
                    case ".jpeg":
                        strContentType = "Image/jpeg";
                        break;
                    case ".Png":
                        strContentType = "Image/PNG";
                        break;
                    case ".gif":
                        strContentType = "Image/GIF";
                        break;
                }
                if (strContentType != string.Empty)
                {
                    Stream fStream = FupStudent.PostedFile.InputStream;
                    BinaryReader bReader = new BinaryReader(fStream);
                    Byte[] bytes = bReader.ReadBytes((int)fStream.Length);
                    if (sqlCon.State == ConnectionState.Closed)
                    {
                        sqlCon.Open();
                    }
                    SqlCommand cmd = new SqlCommand("StudentAdd", sqlCon); // see the stored procedure below
                    cmd.CommandType = CommandType.StoredProcedure;
                    cmd.Parameters.AddWithValue("@firstName", txtFirstName.Text);

                    cmd.Parameters.Add(new SqlParameter("@Photo", DbType.Binary));
                    cmd.Parameters["@Photo"].Value = FupStudent.PostedFile;
                    int inCount=cmd.ExecuteNonQuery();
                    if (inCount > 0)
                    {
