How to read xml data in C#

Question

I'm trying to read an xml and display its data in a form. Following is the code generated with the form. If I want to just display "Hello World" from a tab value in XML, where should I put the code in the C# code generated by the VB form, if my Xml schema (test.xml)is as below.

   <tab>
        <message>Hello World</Message>
   </tab>

Following is the code generated by the form. I included System.Xml to read the Xml file. Any help is greatly appreciated. Thank you

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Data.SqlClient;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace xmldatatest
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            XmlDocument doc = new XmlDocument();
            doc.Load("C:\\test.xml");
        }
     }
 }

Correct your XML File to be valid:

<?xml version="1.0" encoding="utf-8" ?>
<tab>
    <message>Hello World</message>
</tab>

C# code should be like:

public partial class Form1 : Form
{
    public Form1()
    {
        XmlDocument doc = new XmlDocument();
        doc.Load("C:\\test.xml");

        var node = doc.SelectSingleNode("/tab/message");

        // Gets "Hello World"
        var message = node.InnerText;

        // you can do whatever with the message now...
    }
}

The XML example you supplied is not valid:

<tab>
     <message>Hello World</Message>
</tab>

Your message tag starts with this <message> but ends with this </Message>.
