C#/REST Getting files in a document library using Internal Name

Question

Hi Folks,
I need to get a list of files in a SP2010 and SP2013 document library using the REST API - this is occurring inside a timer service application so am using C#.  As a constraint I need to use the internal names for the document libraries - primarily
because users tend to change the display name and this is an automated service.
When I make a call to _api/web/GetFolderByServerRealitveUrl('/Shared Documents')/Files  I get a bunch of XML but how do I get just a list of filename+ext.   I am using Xdocument (LINQ to XML). I need to retrieve the name property in the
contents sub element for all files returned.
Second question, how to I change this to use the internal name '/Document' instead of '/Shared Document', so that it copes with users changing the display name of document libraries.
Regards
Andy

Hi Andy,
1.For your issue, you can refer to the code as below:
using System.Xml;
namespace REST_XML_LIST_GET
class Program
static XmlNamespaceManager xmlnspm = new XmlNamespaceManager(new NameTable());
static Uri sharepointUrl = new Uri("Site URL/");
static void Main(string[] args)
xmlnspm.AddNamespace("atom", "http://www.w3.org/2005/Atom");
xmlnspm.AddNamespace("d", "http://schemas.microsoft.com/ado/2007/08/dataservices");
xmlnspm.AddNamespace("m", "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata");
NetworkCredential cred = new System.Net.NetworkCredential("username", password", "domain");
HttpWebRequest listRequest = (HttpWebRequest)HttpWebRequest.Create(sharepointUrl.ToString() + "_api/Web/lists/getByTitle('List Name')/items");
listRequest.Method = "GET";
listRequest.Accept = "application/atom+xml";
listRequest.ContentType = "application/atom+xml;type=entry";
listRequest.Credentials = cred;
HttpWebResponse listResponse = (HttpWebResponse)listRequest.GetResponse();
StreamReader listReader = new StreamReader(listResponse.GetResponseStream());
var listXml = new XmlDocument();
listXml.LoadXml(listReader.ReadToEnd());
//Method 1 Seperate node list
var titleList = listXml.SelectNodes("//atom:entry/atom:content/m:properties/d:Title", xmlnspm);
var idList = listXml.SelectNodes("//atom:entry/atom:content/m:properties/d:ID", xmlnspm);
int i = 0;
foreach (XmlNode title in titleList)
Console.WriteLine(title.InnerXml+" "+idList[i++].InnerXml);
//Method 2 single node list
var prop = listXml.SelectNodes("//atom:entry/atom:content/m:properties", xmlnspm);
foreach (XmlNode ndlist in prop)
Console.WriteLine(ndlist.SelectSingleNode("d:Title", xmlnspm).InnerXml + " " + ndlist.SelectSingleNode("d:ID", xmlnspm).InnerXml);
Console.ReadLine();
2. For a workaround, you can get the display name based on the internal name and use the display name in the Rest API.
