                                ...........................

And I need to get values and put inside a string

I try to do this:

var ListaChave = new List<string>();

var lista = (from c in xDoc.Descendants(ns + "/rem/chave") select c.Value).ToList();

foreach (string s in lista)
  {
    add the values.....
  }

But the s var is null. I don´t know how to get these values. Anybody can help me please!?

Use linq to xml

XDocument doc = XDocument.Load("XMLFile1.xml");

XNamespace ns = @"http://www.portalfiscal.inf.br/cte";

List<string> strList = doc.Descendants(ns+"rem").Descendants(ns+"chave").Select(e => e.Value).ToList();

and alternatively, you can have more control by doing things like

You're missing an element in the path you passed to Descendants. In your XML document the chave elements are children of infNFe. Your LINQ query is looking for chave elements under "rem", and not finding any, hence the null result.

Change your query to this:

var lista = (from c in xDoc.Descendants(ns + "/rem/infNFe/chave") 
             select c.Value).ToList();

And you should get what you're looking for, as long as the ns is set correctly.

You can try with this code by just adding the infNFe:

var ListaChave = new List<string>();

var lista = (from c in xDoc.Descendants(ns + "/rem/infNFe/chave") 
             select c.Value).ToList();

foreach (string s in lista)
{
   add the values.....
}
