Read XML files from Folder using XDocument in ASP.Net

Using XDocument.load in a loop to read all Xml in a folder i get only the first file.

What i wrong?

in a page (webform) i allow user to upload multiple xml with a button

with another button user can save on db files selected

if i select just one file  it works well but if i select multiple file only the first will be saved.

so to test the code il simple print the document on page and i saw that 

with multiple selection the first file is printed two times if i select two files and so on.

    IEnumerable<string> filesUploaded = Directory.EnumerateFiles(Server.MapPath("~/SFA_XML_Upload/"), "*")
                                             .Select(f => Path.GetFileName(f));
    int ordcliRowsInserted = 0;
 
    foreach (var file in filesUploaded)
    {
        string filename = Server.MapPath("~/SFA_XML_Upload/" + file);
 
        var doc = XDocument.Load(filename);
        Response.Write(doc.ToString());
        //ordcliRowsInserted += SaveDataBaseOrdcli(ReadOrdcli(doc, filename));
         
    }
