如何使用XmlWriter / XmlReader读取/写入复杂对象

Question

I've been trying to find an easy way to write XML using the XmlReader/XmlWriter. I don't really like using the interface "IXmlSerializable", but I've got no choice for some of my dataclass.

Anyway, what I want to do is quite simple:

private MyClass myObject;
public void WriteXml(XmlWriter writer)
{
    writer.WriteObject(myObject); // <-- this method doesn't exists
}

So, I found 2 work around:

1. Write my own routine to write my object manually. Quite ridiculous since .Net already does it.
2. Create a new serializer using a StringWriter and use the WriteValue(string) method.

I haven't tested the second yet but I think it will probably work (not sure because of the ReadValue result).

Then my question is: Am I missing something important or is it the only way? Or is there a better way to handle that?

Thanks.

After playing around, I found something quite simple. Here is the code I was playing with for those who are wondering how I fixed my problem (similar for reading and element):

    public static void WriteElement(XmlWriter writer, string name, object value)
    {
        var serializer = new XmlSerializer(value.GetType(), new XmlRootAttribute(name));
        serializer.Serialize(writer, value);
    }

I don't know why I was complicating the problem, but it cannot be more simpler than that.

Try using the XmlDocument class. It uses the XmlNode as the basis for easily writing out xml. You can also serialize a class, or use the DataSet class to write out xml, or read it back into a dataset or XmlDocument type structure.
