重构问题

    public static string[] Foo(System.IO.Stream stream)
    {
        XmlTextWriter xmlWriter = new XmlTextWriter(stream,   System.Text.Encoding.ASCII);

        xmlWriter.WriteStartDocument();
        xmlWriter.WriteStartElement("Element");
        xmlWriter.WriteEndElement();
        xmlWriter.WriteEndDocument();
        xmlWriter.Flush();

        return new string[3]{"1", "2", "3"};
    }

和一个呼叫代码

using(MemoryStream memStream = new MemoryStream())
{
     string[] playerIDs = PlayerCommand.Foo(stream);
     // do some stuff with stream and playerIDs
}

提前感谢,, 格雷格
