In the .Net there is a Namespace called XML where you can grab the Class XmlDocument.

XmlDocument xmlDoc = new XmlDocument();

and use a method called LoadXml(string xml) to load the xml into the XmlDocument Object.

When the Xml is loaded into the XmlDocument object you can view it's attributes and element using the properties inside the XmlDocument.

For more info see MSDN Documentation on XmlDocument: msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx

There is another interesting feature in C# namely XML Serialization. You can read from / to a class to / from xml. A convenient way of using C# for reading and writing xml data.

XmlDocument xDoc = new XmlDocument();
xDoc.Load(@"your_xml_file_Path.xml");
XmlNodeList Fname = xDoc.GetElementsByTagName("Fname");
XmlNodeList Lname = xDoc.GetElementsByTagName("Lname");
textBox1.Text = Fname[0].InnerText;
textBox2.Text = Lname[0].InnerText;

Sample coding snipet for Reading xml Using LINQ to XML conceptws

//namespace

using System.Linq;
using System.Xml.Linq;

public IQueryable ReadXML(string Filepath)
        {
            XDocument doc = XDocument.Load(Filepath);

            var Result = doc.Descendants("Employee").Select(a =>
                new
                {
                    FirstName = a.Element("Fname").Value,
                    LastName = a.Element("LastName").Value,
                    Age = a.Element("Age") != null ? a.Element("Age").Value : "0",
                    Salary = a.Element("Salary").Value,
                    }).AsQueryable();

            return Result;
        }
