Answer 1

You need to create an XmlWriter and call its WriteNode method.

For example:

using (conn)
using (SqlCommand dataCmd = new SqlCommand(sqlText, Conn)) {
    dataCmd.CommandTimeout = 60000;

    Conn.Open();
    using (XmlReader dataReader = dataCmd.ExecuteXmlReader())
    using (XmlWriter writer = XmlWriter.Create(File.OpenWrite(...)) {
        writer.WriteNode(dataReader, true);
    }
}

Answer 2

The simplest way would be to pass it into an XmlWriter, using a method such as this:

public void WriteOutXml(XmlReader xmlReader, string fileName)
{
    var writer = XmlWriter.Create(fileName);
    writer.WriteNode(xmlReader, true);
}
