Here is a small example of making a GetQuoteSnap request for a couple symbols and pulling the symbol and last price from the result.

using System;
using System.Net;
using System.Threading.Tasks;
using System.Xml.Linq;

class Program
{
    static void Main(string[] args)
    {
        string username = "username";
        string password = "password";
        
        // The symbols to request in an array
        string[] symbols = { "@C@1", "@C@2" };

        // Join the array into a comma-separated string
        string joinedSymbols = string.Join(",", symbols);

        // Insert the credentials and symbols into the URL
        string url = String.Format("https://pxweb.dtn.com/PXWebSvc/PXServiceWeb.svc/GetQuoteSnap?UserID={0}&Password={1}&Type=P&Symbol={2}&SymbolLimit=&PageToken=&Market=&Vendor=&Format=", username, password, joinedSymbols);

        ServicePointManager.Expect100Continue = true;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

        // Make an HTTP GET request to the URL
        using (var client = new WebClient())
        {
            try
            {
                string xmlResponse = client.DownloadString(url);

                // Parse the XML response
                XDocument doc = XDocument.Parse(xmlResponse);

                // Find all Quote elements and print their TickerSymbol attributes
                var quotes = doc.Descendants("Quote");
                foreach (var quote in quotes)
                {
                    string tickerSymbol = quote.Attribute("TickerSymbol").Value;
                    string last = quote.Element("Last").Value;
                    Console.WriteLine(String.Format("{0} : {1}", tickerSymbol, last));
                }
            }
            catch (WebException e)
            {
                Console.WriteLine(String.Format("Error: {0}", e.Message));
            }
            catch (Exception e)
            {
                Console.WriteLine(String.Format("An error occurred: {0}", e.Message));
            }
        }
    }
}
