I am trying to convert collection class to xml data and append that xml data to xml file
here is my function’

  public void XmlWriter(List<Email> Femails)
    {
        string ErrorXmlFile = @"../../Retries.xml";
        try
        {
            if (!File.Exists(ErrorXmlFile))
            {
                XmlSerializer xSeriz = new XmlSerializer(typeof(List<Email>));
                FileStream fs = File.Open(ErrorXmlFile, FileMode.Append, FileAccess.Write, FileShare.ReadWrite);
                xSeriz.Serialize(fs, Femails);

            }
            else 
            {
                foreach(Email email in Femails)
                {
                XmlDocument doc = new XmlDocument();
                doc.Load(ErrorXmlFile);
                XmlNode xnode = doc.CreateNode(XmlNodeType.Element, "ArrayOfEmail", null);
                XmlSerializer xSeriz = new XmlSerializer(typeof(Email));
                StringWriter sw = new StringWriter();
                xSeriz.Serialize(sw,email);
                xnode.InnerXml = Convert.ToString(sw);
                doc.DocumentElement.AppendChild(xnode);
                doc.Save(ErrorXmlFile);
                }
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }

    }

In the above function “femail” is parameter of a List, where Email is userdefind custom class.
First time it checks if the file is existing or not. If not then it works fine now but when i need to append data to my existing file it fails.

As per my above code it converts single Email object to xml data with <?xml version="1.0" encoding="utf-16"?> with this tags which i want to remove before bind.

The output i got from my code is:

<?xml version="1.0"?>
<ArrayOfEmail xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

                XmlSerializer xSeriz = new XmlSerializer(typeof(Email));
                XmlSerializerNamespaces ns = new XmlSerializerNamespaces();

                {
                    xSeriz.Serialize(xmlwriter, email, ns);
                }
                xnode.InnerXml = stringwriter.ToString();
                XmlNode bindxnode = xnode.SelectSingleNode("Email");
                doc.DocumentElement.AppendChild(bindxnode);
                SaveAttachment(email);
            }
