Another peace of code that I don't want to rewrite it again (and again)

using System;
using System.Collections.Generic;

/// <summary>
/// This class uses XmlSerializer to do both sides of conversion to xml string
/// </summary>
/// <typeparam name="T">any Serializable class</typeparam>
public class Serializer<T>
{
    /// <summary>
    /// Convert an instance to XML string
    /// </summary>
    /// <param name="item"></param>
    /// <returns></returns>
    public string Serialize(T item)
    {

        MemoryStream ms = new MemoryStream();
        XmlTextWriter writer = new XmlTextWriter(ms, Encoding.Unicode);

        XmlSerializer serializer = new XmlSerializer(typeof(T));
        serializer.Serialize(writer, item);

        writer.Flush();
        ms.Position = 0;

        StreamReader reader = new StreamReader(ms);
        return reader.ReadToEnd();

    }
    /// <summary>
    /// another version, could be better
    /// </summary>
    /// <param name="item"></param>
    /// <returns></returns>
    private string GetSerialize2(T item)
    {
        StringWriter wr = new StringWriter(new StringBuilder());

        XmlSerializer serializer = new XmlSerializer(typeof(T));
        serializer.Serialize(wr, item);

        wr.Close();
        return wr.GetStringBuilder().ToString();
    }

    /// <summary>
    /// Convert the XML string to an instance of an object
    /// </summary>
    /// <param name="xml"></param>
    /// <returns></returns>
    public T Deserialize(string xml)
    {
        XmlTextReader stream = new XmlTextReader(new StringReader(xml));
        XmlSerializer serializer = new XmlSerializer(typeof(T));
        return (T)serializer.Deserialize(stream);
    }
}
