How to read XML file in C #?

I have the following xml file, I want to know the best way to read this xml file

<MyFile> 
  <Companies> 
    <Company>123</Company> 
    <Company>456</Company>
    <Company>789</Company> 
  </Companies> 
</MyFile>

As an output, I need a set of values ​​like "123,456,789", or it can be an array of strings []

Is it possible to use Linq for xml? How?

var xdoc = XDocument.Load(PATH_TO_FILE);
var companies = xdoc.Descendants("Company").Select(c => (string)c).ToArray();

It will give you string[].

Use LINQ to XML, Include using System.Xml.Linq;

   XDocument xmlDoc = XDocument.Load("yourfile.xml");
   var test = xmlDoc.Descendants("Companies").Elements("Company").Select(r => r.Value).ToArray();
   string result = string.Join(",", test);

Conclusion:

123,456,789

XML DataSet

DataSet dsMenu = new DataSet(); //Create Dataset Object

dsMenu.ReadXml("XMLFILENAME.XML"); // Read XML file in Dataset

DataTable dtXMLFILE// Create DatyaTable object

dtXMLFILE= dsMenu.Tables[0]; // Store XML Data in Data Table

var xmlStr=@"<MyFile> 
  <Companies> 
    <Company>123</Company> 
    <Company>456</Company>
    <Company>789</Company> 
  </Companies> 
</MyFile>";

var xDoc = XDocument.Parse(xmlStr);
var companyIds = xDoc.Descendants("Company").Select(e => (int)e);

string pathToXmlFile = @"C:\test.xml";
XElement patternDoc = XElement.Load(pathToXmlFile);
List<string> values = new List<string>();
foreach (var element in patternDoc.Elements("Companies").Elements("Company"))
{
   values.Add(element.Value);
