c# - Trying to convert an xsl file and an xml file to html and then display that in a WebBrowser object -

so trying convert xml file uses xsl file convert both of html can bind webbrowser object. here have far isnt working:

        protected string convertxslandxmltohtml(string xmlsource, string xslsource)         {          string resultdoc = application.startuppath + @"\result.html";         string htmltopost;           try         {             xpathdocument myxpathdoc = new xpathdocument(xmlsource);             xsltransform myxsltrans = new xsltransform();              //load xsl              myxsltrans.load(xslsource);              //create output stream             xmltextwriter mywriter = new xmltextwriter(resultdoc, null);              //do actual transform of xml             myxsltrans.transform(myxpathdoc, null, mywriter);              mywriter.close();              streamreader stream = new streamreader(resultdoc);             htmltopost = stream.readtoend();             stream.close();              file.delete(resultdoc);              return (htmltopost);            }           catch (filenotfoundexception fileex)          {             messagebox.show("file not found: " + fileex.filename, "file not found error", messageboxbuttons.ok, messageboxicon.error);             return null;         }           catch (exception ex)         {             messagebox.show("general exception: " + ex.message, "exception thrown" , messageboxbuttons.ok, messageboxicon.error);             return null;         }      } 

this code in function returns htmltopost , returning data bound webbrowser this:

            // webreport webbrowser object             // htmlstring html passed function             // bind html text webbrowser object              webreport.navigate("about:blank");             ihtmldocument2 test = (ihtmldocument2)webreport.document.domdocument;             test.write(htmlstring);             webreport.document.write(string.empty);             webreport.documenttext = htmlstring; 

i know xsltransform has been deprecated examples online use thats why using it.

the error :

a runtime error has occured. wish debug?

line: 177 error: expected ')'

it happens when code tries execute:

        ihtmldocument2 test = (ihtmldocument2)webreport.document.domdocument;         test.write(htmlstring);  //this actual line causes error , traces assembly code. 

thanks in advance can give me.

edit #1: if hit no debugging errors page shows like.

i in project

make temp file:

string reporttemppath = path.combine(path.gettemppath(), "pubreport" + guid.newguid().tostring() + ".html"); 

save content:

var root =                 new xelement(ns + "html",                     new xelement(ns + "head",                         new xelement(ns + "title", "publisher report"), 

// ...

var doctype = new xdocumenttype("html",               "-//w3c//dtd xhtml 1.0 strict//en",               "http://www.w3.org/tr/xhtml1/dtd/xhtml1-strict.dtd", null);      var doc =         new xdocument(             new xdeclaration("1.0", "utf-8", "no"),             doctype,             root         );      doc.save(path); 

then pass memorystream webbrowser control.

webbrowser1.documentstream = new memorystream(file.readallbytes(reporttemppath));
