            -<D1><G1>04220040</G1>
            <G2>27-05-2021 01:25:49</G2>
            </D1></UTILITYTYPE></CDF>

Here I want to read value of <g1> tag i.e. 04220040 from many files.

Output

04220040

.

What I have tried:

XmlDocument infodoc = new XmlDocument();
            infodoc.Load("C:\\Users\\himansh.jain\\Downloads\\cesu\\001_04220040_20210527_03162969.xml");
            IEnumerable<XElement> direclty = infodoc.GetElementsByTagName("Settings").Elements("directory");
            var rosterUserIds = direclty.Select(r => r.Value);

Can you please suggest what error am i making or a better way to get the value of <g1> tag.

An attribute 'value' does not exist!

var rosterUserIds = direclty.Select(r => r.Value).SingleOrDefault()

Another way is to use XDocument[^]:

C#

XDocument xdoc = XDocument.Load("full_file_name_here");
var uid = xdoc.Descendants("G1").First()?.Value;

thank you for your solution . Could you please tell where I can study about "Descendants("G1").First()?.Value" usage...i was going through documentation but could not find it .

This part of code, which uses "First" is called Linq to xml. See: Overview - LINQ to XML | Microsoft Docs[^]
