Here is my code which converts Byte code to original string and it works in normal HTML page perfectly,

string sql1 = "SELECT Package FROM Package WHERE ID='1'";
        SqlConnection con1 = new SqlConnection(cls.GetConnectionString());
        SqlCommand cmd1 = new SqlCommand(sql1, con);
        SqlDataAdapter da1 = new SqlDataAdapter(cmd1);
        DataTable dt1 = new DataTable();
        da1.Fill(dt1);
        dt1.Columns.Add("Description");
        foreach (DataRow dr1 in dt1.Rows)
        {
            if (dr1 != null)
            {
                byte[] byt1 = (byte[])dr1[0];
                string str1;
                System.Text.ASCIIEncoding enc1 = new System.Text.ASCIIEncoding();
                str1 = enc1.GetString(byt1);
                dr1[1] = str1;
                description = str1;
               
            }
        }

But i want to write this string into word file in the following way

public void CreateWordFile(DataTable dt)
    {
        Response.Clear();
        Response.Buffer = true;
        Response.AddHeader("content-disposition", "attachment;filename=Publish.doc");        
        Response.Charset = "";
        Response.ContentType = "application/vnd.ms-word ";
        StringWriter sw = new StringWriter();
        HtmlTextWriter hw = new HtmlTextWriter(sw);
        GridView gvTemp = new GridView();
        gvTemp.AllowPaging = false;
        gvTemp.DataSource = dt;
        gvTemp.DataBind();
        gvTemp.RenderControl(hw);
        Response.Output.Write(sw.ToString());
        Response.Flush();
        Response.End();
    }

Now here is output

<p style="margin: 0px; text-align: center;">Header</p> <p style="margin: 0px; text-align: center;">Color <span style="color: #ff0000;">Red</span></p><br /> <p style="margin: 0px; text-align: center;">Heading</p>
<table width="100%" cellspacing="1" border="0" id="table1"> <tbody> <tr> <td> <p align="center">TITLE</p></td> <td width="9">&nbsp;</td></tr> <tr> <td width="11">&nbsp;</td> <td>&nbsp;</td> <td width="9">&nbsp;</td></tr> <tr> <td width="11">&nbsp;</td> <td> <p align="justify"><b>Description</b><br /> Details &amp;.</p></td> <td width="9">&nbsp;</td></tr> <tr> <td width="11">&nbsp;</td> <td>&nbsp;</td> <td width="9">&nbsp;</td></tr> <tr> <td width="11">&nbsp;</td> </tr></tbody></table>
><span style="font-weight: bold;">Color</span></p><span style="font-weight: bold;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Footer</span>

So please guide me how to publish this above in a word file?
