c# - Writing to user defined XML file -

i have been following youtube tutorial on creating lists , saving/loading them xml files. however, have been playing around , cant quite seem head around having dialog box appear , let user select location , enter file name themselves. @ moment predefined file name , location on written every time save it. not want.

here code:

    private void button6_click(object sender, eventargs e)     {         string path = directory.getcurrentdirectory();          if (!directory.exists(path + "\\tasklist")) // if file directory doesnt exist..             directory.createdirectory(path + "\\tasklist"); // create file directory          if (!file.exists(path + "\\tasklist\\settings.xml")) // if xml file doesnt exist..         {             xmltextwriter xw = new xmltextwriter(path + "\\tasklist\\settings.xml", encoding.utf8); // create xml file             xw.writestartelement("tasklist");             xw.writeendelement();             xw.close();         }          // create xml document write         xmldocument xdoc = new xmldocument();         xdoc.load(path + "\\tasklist\\settings.xml");          // create node every property inside taskproperties class         foreach (taskproperties newtask in task)         {             xmlnode nodetop = xdoc.createelement("task");             xmlnode nodetitle = xdoc.createelement("title");             xmlnode nodedescription = xdoc.createelement("description");             xmlnode nodepriority = xdoc.createelement("priority");             xmlnode nodecompletiondate = xdoc.createelement("completiondate");             xmlnode nodetaskcomplete = xdoc.createelement("taskcomplete");              nodetitle.innertext = newtask.title;             nodedescription.innertext = newtask.description;             nodepriority.innertext = newtask.priority;             nodecompletiondate.innertext = newtask.completiondate.tofiletime().tostring(); // convert file time (numbers) string             nodetaskcomplete.innertext = newtask.taskcomplete;              // add these nodes 'nodetop' node             nodetop.appendchild(nodetitle);             nodetop.appendchild(nodedescription);             nodetop.appendchild(nodepriority);             nodetop.appendchild(nodecompletiondate);             nodetop.appendchild(nodetaskcomplete);             // add nodetop document             xdoc.documentelement.appendchild(nodetop);         }         // save document         xdoc.save(path + "\\tasklist\\settings.xml");     } 

any on how can achieve appreciated.

use open file save dialog box , location user selects.

savefiledialog fdgsave= new savefiledialog();  fdgsave.initialdirectory = convert.tostring(directory.getcurrentdirectory());  fdgsave.filter = "xml (*.xml)|*.xml|all files (*.*)|*.*" ;  fdgsave.filterindex = 1;   if(fdgsave.showdialog() == dialogresult.ok)  {      console.writeline(fdgsave.filename);//do want here }
