,and I wanna get the value of the attribute "Name" in the file. This is what i've tried to do.

var docXml = new XmlDocument();

docXml.Load("path");
var node = docXml.SelectNodes("Process");

 var process = docXml.SelectSingleNode("/Process").Attributes["/Name"].Value;

Console.WriteLine(process);

var docXml = new XmlDocument();

docXml.Load("path");
var node = docXml.SelectNodes("Process");

 var process = docXml.SelectSingleNode("/Process").Attributes["/Name"].Value;

Console.WriteLine(process);

But I keep received null reference exception. Can someone check at point out where i got the problem ?

try this:

        var xml = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?><Root><Process Name=\"sublime_text\"><StartTime>14/11/2022 02:20:56</StartTime><KilledTime>14/11/2022 02:20:56</KilledTime></Process></Root>";
        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.LoadXml(xml);
        
        var node = xmlDoc.SelectSingleNode("/Root/Process").Attributes["Name"];
        Console.WriteLine(node.InnerText);

        var xml = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?><Root><Process Name=\"sublime_text\"><StartTime>14/11/2022 02:20:56</StartTime><KilledTime>14/11/2022 02:20:56</KilledTime></Process></Root>";
        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.LoadXml(xml);
        
        var node = xmlDoc.SelectSingleNode("/Root/Process").Attributes["Name"];
        Console.WriteLine(node.InnerText);
