c# - How do I load multiple XML files and read them? -

i've problem. in code i'm looking xml files in 1 directory. works don't know how read them. single 1 loaded string xmlfile. think need replace or edit in way code xmlfile not 1 file, files found in directory.

what should doing?

namespace windowsformsapplication11 {     public partial class form1 : form     {         private const string xmlfile = "c:\games\games.xml"; // single xml file works          public form1()         {             this.initializecomponent();             this.initializelistview();             this.loaddatafromxml();         listview.items.addrange(directory.getfiles("c:\games\", "*.xml")                                  .select(f => new listviewitem(f))                                  .toarray());          }          private void loaddatafromxml()         {             if (file.exists(xmlfile))             {                 xdocument document = xdocument.load(xmlfile);                 if (document.root != null)                 {                     foreach (xelement gameelement in document.root.elements("game"))                     {                         string gamename = gameelement.element("gamename").value;                         string launchpath = gameelement.element("launchpath").value;                         string uninstallpath = gameelement.element("uninstallpath").value;                         string publisher = gameelement.element("publisher").value;                         // check if gameelement.element(elementname) not null                           game game = new game(gamename, launchpath, uninstallpath, publisher);                         addgametolistview(game);                     }                 }             }         }          private void addgametolistview(game game)         {             listviewitem item = creategamelistviewitem(game);             this.listview.items.add(item);         }          private listviewitem creategamelistviewitem(game game)         {             listviewitem item = new listviewitem(game.gamename);             item.subitems.add(game.launchpath);             item.subitems.add(game.uninstallpath);             item.subitems.add(game.publisher);             item.tag = game;             return item;         }            private void initializelistview()         {             this.listview.view = view.details;             this.listview.gridlines = true;             this.listview.multiselect = false;             this.listview.fullrowselect = true;             this.listview.columns.addrange(new[]                 {                     new columnheader{text = "gamename", width = 200},                     new columnheader{text = "launchpath"},                     new columnheader{text = "uninstallpath"},                     new columnheader{text = "publisher"}                  });             this.listview.mousedoubleclick += listviewonmousedoubleclick;         }          private void listviewonmousedoubleclick(object sender, mouseeventargs e)         {             if (e.button == mousebuttons.left && this.listview.selecteditems.count > 0)             {                 game game = (game)((this.listview.selecteditems[0].tag);                 try                 {                     process.start(game.launchpath);                 }                 catch (exception ex)                 {                     messagebox.show("can not start game.\ndetails:\n" + ex.message, "error", messageboxbuttons.ok,                                     messageboxicon.error);                 }             }         }     }      internal class game     {         public game()         {          }          public game(string gamename, string launchpath, string uninstallpath, string publisher)         {             this.gamename = gamename;             this.launchpath = launchpath;             this.uninstallpath = uninstallpath;             this.publisher = publisher;         }         public string gamename { get; set; }         public string launchpath { get; set; }         public string uninstallpath { get; set; }         public string publisher { get; set; }     } } 

update:

this current code. how can send f loaddatafromxml ?

      public form1()     {         this.initializecomponent();         this.initializelistview();         this.height = screen.primaryscreen.workingarea.height;         var files = directory.getfiles(@"c:\games\", "*.xml").select(f => new listviewitem(f)).toarray(); listview.items.addrange(files);         foreach (var f in files)         {             this.loaddatafromxml(f);         }      }      private void loaddatafromxml(//what need enter here?)     {                  foreach (xelement gameelement in f.root.elements("game"))                 {                     string gamename = gameelement.element("gamename").value;                     string launchpath = gameelement.element("launchpath").value;                     string portablesave = gameelement.element("portablesave").value;                     string publisher = gameelement.element("publisher").value;                     string gameid = gameelement.element("gameid").value;                     string update = gameelement.element("update").value;                     // check if gameelement.element(elementname) not null                       game game = new game(gamename, launchpath, portablesave, publisher, gameid, update);                     addgametolistview(game);                 }       } 

simple use directory functions xml files, , loop through them, calling loaddatafromxml each file. note: need refactor code little bit.

you need modify loaddatafromxml take file parameter. , change form1 constructor this

public form1() {     this.initializecomponent();     this.initializelistview();     var files = directory.getfiles("c:\games\", "*.xml")                          .select(f => new listviewitem(f))                          .toarray();     listview.items.addrange(files);      foreach(var f in files)     {         this.loaddatafromxml(f);     } }
