ASP.net - Input string was not in a correct format. for HTMLWorker.ParseToList

Question

I am using

HTMLWorker.ParseToList(New StringReader(HTMLCode), New StyleSheet)

On a String HTMLCode that contains :

  <html>
    <body>
    <table width="auto;">  
        <tr style="color:white ; background: #336699; font-style:bold;">
        <th width="257px;" height="40" >Service Name</th>
        <th width="100px;" height="40">Hits </th>
        <th width="100px;" height="40">Revenue</th>
        <th width="100px;" height="40">Service Cost</th>
        </tr>

        <tr>  
        <td width="257px;" height="30" >  GtalkDay </td> 
        <td width="257px;" height="30" > 320 </td> 
        <td width="257px;" height="30" >  67.20 </td> 
        <td width="257px;" height="30" >  (0.21 K) </td>
        </tr>

        <tr style="background: #EBEBE0">  
        <td width="257px;" height="30" >  TwitterDay </td> 
        <td width="257px;" height="30" > 885 </td> 
        <td width="257px;" height="30" >  185.85 </td> 
        <td width="257px;" height="30" >  (0.21 K) </td>
        </tr>

        <tr>  
        <td width="257px;" height="30" >  YahooDay </td> 
        <td width="257px;" height="30" > 626 </td> 
        <td width="257px;" height="30" >  131.46 </td> 
        <td width="257px;" height="30" >  (0.21 K) </td>
        </tr> 

        </table>
    </body>
    </html>

And it is returning the error:

Input string was not in a correct format.

What could be the problem? the HTML code looks perfectly fine.

all Help would be appreciated

PS: I tried to remove Width and Height and Background attributes and the Parsing worked fine

Have you tried using single quotes in place of double quotes? — Nipun Ambastha

@NipunAmbastha Yes and it's still returning the same error... what could be the reason? — HelpASisterOut

Ok, we can debug it more. i.e. What and where issue is coming? Take new variable and assign its value New StringReader(HTMLCode); check if this is fine. Also what you have in stylesheet? — Nipun Ambastha

@NipunAmbastha I tried to remove all the width and background color parameters and the saving to pdf worked fine. Does this mean I can only save plain html? — HelpASisterOut

Yes, HTMLParser might not accept the tag properties. Probably you will need to search out some other way to create PDF — Nipun Ambastha

This might be due to the not proper format of your HTML.

you should remove spaces before the closing tags of you HTML tags as shown below:

Make change of this,

<td width="257px;" height="30" >  GtalkDay </td>

to

<td width="257px;" height="30">GtalkDay</td>
