try this code private void SaveButton_Click( object sender EventArgs e) { MemoryStream fingerprintData = new MemoryStream(); Template.Serialize(fingerprintData); fingerprintData.Position = 0; BinaryReader br = new BinaryReader(fingerprintData); Byte[] bytes = br.ReadBytes((Int32)fingerprintData.Length); //Insert the file into database SqlConnection cn = new SqlConnection( Data Source=10.115.5.3; Initial Catalog=EnrollmentSampledb;Integrated Security=SSPI; ); SqlCommand cmd = new SqlCommand( INSERT INTO tblUser VALUES(@ID_NUMBER @FIRSTNAME @LASTNAME @FINGERPRINT @DATE_ADDED @DATE_MODIFIED)  cn); cmd.Parameters.Add( ID_NUMBER  SqlDbType.NVarChar).Value = tboxIdNum.Text; cmd.Parameters.Add( FIRSTNAME  SqlDbType.NVarChar).Value = tboxFname.Text; cmd.Parameters.Add( LASTNAME  SqlDbType.NVarChar).Value = tboxLname.Text; cmd.Parameters.Add( FINGERPRINT  SqlDbType.Image).Value = bytes; cmd.Parameters.Add( DATE_ADDED  SqlDbType.DateTime).Value = DateTime.Now; cmd.Parameters.Add( DATE_MODIFIED  SqlDbType.DateTime).Value = DateTime.Now; cn.Open(); cmd.ExecuteNonQuery(); cn.Close(); tboxIdNum.Text =  ; tboxFname.Text =  ; tboxLname.Text =  ; }
