i read long string , output first 3 paragraphs of string. how achieve this? wanted use code show (n) number of words have since changed paragraphs. 

public string mysummary(string html, int max) {     string summaryhtml = string.empty;      // load our html document     htmldocument htmldoc = new htmldocument();     htmldoc.loadhtml(html);      int wordcount = 0;         foreach (var element in htmldoc.documentnode.childnodes)     {         // inner text strip out html, , give plain text         string elementtext = element.innertext;          // split space words in element         string[] elementwords = elementtext.split(new char[] { ' ' });          // , if haven't used many words ...          if (wordcount <= max)         {             // add *outer* html (which have proper              // html formatting fragment) summary             summaryhtml += element.outerhtml;             wordcount += elementwords.count() + 1;          }         else         {             break;         }     }      return summaryhtml ; }

if paragraphs mean <p> tags, childnodes of document <p>s , pull first 3's inner text?

something like:

string.join(doc.documentelement.selectnodes("//p").take(3).select(n => n.text).toarray(), " ");
