可以将XML直接序列化为字符串而不是C#的Stream吗？

This example使用StringWriter来保存序列化数据，然后调用ToString()给出实际的字符串值：

Person john = new Person();
XmlSerializer xmlSerializer = new XmlSerializer(typeof(Person));
StringWriter stringWriter = new StringWriter();
xmlSerializer.Serialize(stringWriter,john);
string serializedXML = stringWriter.ToString();

有没有更简单/更清洁的方式来做到这一点？所有的Serialize()重载似乎都使用Stream或Writer。

更新：询问有关serializing an IEnumerable via an Extension Method的类似问题。

有扩展方法的乐趣…

var ret = john.ToXmlString()

public static class XmlTools
{
    public static string ToXmlString<T>(this T input)
    {
        using (var writer = new StringWriter())
        {
            input.ToXml(writer);
            return writer.ToString();
        }
    }
    public static void ToXml<T>(this T objectToSerialize,Stream stream)
    {
        new XmlSerializer(typeof(T)).Serialize(stream,objectToSerialize);
    }

    public static void ToXml<T>(this T objectToSerialize,StringWriter writer)
    {
        new XmlSerializer(typeof(T)).Serialize(writer,objectToSerialize);
    }
}
