This code is requesting multiples files but only saving one of them. Could someone tell me how I can store multiple files using this code?

This is the part of the code that is storing

System.Xml.Serialization.XmlSerializer x = new System.Xml.Serialization.XmlSerializer(response.GetType());
System.IO.TextWriter tw = new System.IO.StreamWriter("D:\\chamila\\XMLTest\\text.xsd");
x.Serialize(tw, response);
tw.Flush();
tw.Close();
