First you need to get the actual HTML of the page, I've never used any WebBrowser control so I don't know if they make it easy by providing a property or not, and as I don't know what UI framework you're using I won't spend time on looking it up, but I'm sure you can figure that out yourself.

Once you have the HTML you need to parse/scrape it, so you have to look for a pattern you can search for in the HTML-string if there is only one table that pattern could be "<table" once you've found the start of the table you just find the "<td" and take all text between ">" and "</" and you repeat that until you hit "</table>"

Solution 2

You can access and manipulate the page using the WebBrowser.Document[^] property. The HtmlDocument.GetElementById[^] would probably allow you to access the table more or less directly.

Nice that's really simple, though it will only work if there actually is an id :).

Thanks Simon, if there is no id, he will have to traverse the dom :)

Seems like such a hassle to me, much simpler with regular expressions, if one knows regex that is :)
