Use File ReadAllText path to file  to read

User · Answer

Use File ReadAllText passing file location as an argument   However  if your real goal is to parse html then I would recommend using Html Agility Pack

What kind of processing are you trying to do   You can do XmlDocument doc   new XmlDocument    followed by doc Load filename    Then the XML document can be parsed in memory   Read here for more information on XmlDocument     MSDN C  Corner tutorial

This is mostly covered already  but one addition as I ran into an issue with the previous code samples   Dim strHTML as String   System IO File ReadAllText HttpContext Current Server MapPath    folder filename html

You can do it the simple way   string pathToHTMLFile     C  temp someFile html   string htmlString   File ReadAllText pathToHTMLFile     Or you could stream it in with FileStream StreamReader   using  FileStream fs   File Open pathToHTMLFile  FileMode Open  FileAccess ReadWrite         using  StreamReader sr   new StreamReader fs                 htmlString   sr ReadToEnd              This latter method allows you to open the file while still permitting others to perform Read Write operations on the file   I can t imagine an HTML file being very big  but it has the added benefit of streaming the file instead of capturing it as one large chunk like the first method
