 htmlBuilder.Append("<table border="1px" cellpadding="5" cellspacing="0" hold=" /&gt; htmlBuilder.Append(" style="border: solid 1px Black; font-size: small;">");
 
 //Create Header Row
 htmlBuilder.Append("&lt;tr align="left" valign="top"&gt;");
 
 foreach (DataColumn targetColumn in targetTable.Columns)
 {
  htmlBuilder.Append("<td align="left" valign="top">");
  htmlBuilder.Append(targetColumn.ColumnName);
  htmlBuilder.Append("</td>");
 }
 
 htmlBuilder.Append("</tr>");
 
 //Create Data Rows
 foreach (DataRow myRow in targetTable.Rows)
 {
  htmlBuilder.Append("<tr align="left" valign="top">");
 
  foreach (DataColumn targetColumn in targetTable.Columns)
  {
   htmlBuilder.Append("<td align="left" valign="top">");
   htmlBuilder.Append(myRow[targetColumn.ColumnName].ToString());
   htmlBuilder.Append("</td>");
  }
 
  htmlBuilder.Append("</tr>");
 }
 
 //Create Bottom Portion of HTML Document
 htmlBuilder.Append("</table>");
 htmlBuilder.Append("</body>");
 htmlBuilder.Append("</html>");
 
 //Create String to be Returned
 htmlString = htmlBuilder.ToString();
 
 return htmlString;
}

Using these above code I have already converted a datatable into html format; Now i want to write these html string into a html file and want to display it.

Can anyone suggest me how to do this?
Thanks in advance.

Solution 1

A html file is just a simply text file with the file extension *.html. So, just write the string to a textfile - simple.
To write the html string to a file see:

To open the file with your prefered web browser:

C#

System.Diagnostics.Process.Start(fileName);

Use StreamWriter class and write your string to a text file having .htm extension.

Solution 3

string filename = "temp.html";
            StreamWriter swXLS = new StreamWriter((MapPath("Logs\\")) + filename);
            swXLS.Write(html.ToString());
            swXLS.Close();
            string attachment = "attachment; filename=" + filename;
            Response.AddHeader("content-disposition", attachment);
            Response.Redirect("~/Officer/Logs/temp.html");
            Response.Write(html.ToString());
            Response.End();

Your answer is correct but IMO we should not spoonfeed people with readymade code snippets. We can provide them a link from where they can learn it.
