图像未保存在数据库中

我在数据库中插入图像。问题是当我单击上传除图像之外插入数据库的所有记录时。代码未生成任何错误。表中的图像列为空。

提前谢谢。

这是我的代码：

        int length = FileUpload1.PostedFile.ContentLength;
        byte[] pic = new byte[length];
        FileUpload1.PostedFile.InputStream.Read(pic, 0, length);
        try
        {
            SqlConnection con = new SqlConnection(conn);
            con.Open();
            //inserting uploaded image query
