我的代码可以很好地创建pdf，但是我没有正确的代码将我的doc文件转换为字节。

我知道如何添加到数据库中。我只想知道我们如何将动态创建的pdf转换为字节。

string attachment = "attachment; filename=" + TextBox1.Text + ".pdf";`

Response.ClearContent();
Response.AddHeader("content-disposition",attachment);
response.contenttype = "application/pdf";
StringWriter s_tw = new StringWriter();
HtmlTextWriter h_textw = new HtmlTextWriter(s_tw);
h_textw.AddStyleAttribute("font-size","7pt");
h_textw.AddStyleAttribute("color","Black");                   
Panel1.RenderControl(h_textw);//Name of the Panel
Document doc = new Document();
doc = new Document(PageSize.A4,5,15,5);
FontFactory.GetFont("Times New Roman",14);
PdfWriter.GetInstance(doc,Response.OutputStream);
doc.Open();
StringReader s_tr = new StringReader(s_tw.ToString());
HTMLWorker html_worker = new HTMLWorker(doc);
html_worker.Parse(s_tr);                
//doc.Close();//Response.Write(doc);
//Response.End();

在这两个代码之间寻找正确的代码[将文档转换为字节]

using (mysqlcommand cmd1 = new mysqlcommand(query1))
{
    cmd1.Connection = con1;
    cmd1.Parameters.AddWithValue("@clientid1",TextBox1.Text);
    cmd1.Parameters.AddWithValue("@username",Session["username"].ToString());
    cmd1.Parameters.AddWithValue("@Name",filename);
    cmd1.Parameters.AddWithValue("@ContentType",contentType);
    cmd1.Parameters.AddWithValue("@Data",bytes);
    con1.Open();
    cmd1.ExecuteNonQuery();
    con1.Close();
    //    }
}                           
}                                
}
}
Response.Redirect("mydoc.aspx");
}
