Question

I am trying to get the message box to show the elements but messagebox will not pop when I run the application

string xml = @"<?xml version='1.0' encoding='UTF-8'?>
<widgets>
    <widget>
        <url>~/Portal/Widgets/ServicesList.ascx</url>
        <castAs>ServicesWidget</castAs>
        <urlType>ascx</urlType>
        <parameters>
            <PortalCategoryId>3</PortalCategoryId>
        </parameters>
    </widget>
    <widget>
        <url>www.omegacoder.com</url>
        <castAs>ServicesWidget</castAs>
        <urlType>htm</urlType>
        <parameters>
            <PortalCategoryId>41</PortalCategoryId>
        </parameters>
    </widget>
</widgets>";

XDocument loaded = XDocument.Parse( xml );

var widgets = from x in loaded.Descendants( "widget" )
              select new
              {
                  URL = x.Descendants( "url" ).First().Value,
                  Category = x.Descendants( "PortalCategoryId" ).First().Value
              };

MessageBox.Show("one");
foreach ( var wd in widgets ){
MessageBox.Show("two");

 }

MessageBox.Show(“one”); shows up.
MessageBox.Show(“two”); never pops up

Also what if I wanna see a count of widgets> I am new to C#
thanks

You can replace your LINQ query with:

var widgets = from x in loaded.Descendants("widgets").Descendants( "widget" )
          select new
          {
              URL = x.Descendants( "url" ).First().Value,
              Category = x.Descendants( "PortalCategoryId" ).First().Value
          };

UPDATE:
Both versions of LINQ should work correctly. My mistake, Descendants can point not only to directly nested nodes, but to all the nodes in the subtree.

Probable issue cause:
However, be aware that in order to show the second message box, you have to close the first one. I’ve just tested this and it worked.

Suggested solution:
In order to be available to show multiple dialogs with messages, you can just create your own form class in the project, instantiate it and show it with Show() method i.e.:
you can add a new Windows Form, call it MessageForm and use the following code:

//MessageBox.Show(new Form(), "one");
        MessageForm msgDlg = new MessageForm() { Message = "one" };
        msgDlg.Show(this);
        foreach (var wd in widgets)
        {
            //MessageBox.Show(new Form(), "two");
            MessageForm msgDlgS = new MessageForm() { Message = "two" };
            msgDlgS.Show(this);
        }

It should work as intended then.
