Help with Serializing an Array of a custom object

Very straight forward but am drawing blanks. Been googling for the last day and a half and haven't found a good example that I can use to make work.

Code:

---

[XmlRoot(Namespace = "http://mynamespace.com")]
public class Documents
{
    [XmlArray]
    [XmlArrayItem(typeof(Document))]
    public ArrayList MyDocuments { get; set; }

    public void Add(Document document)
    {
        MyDocuments.Add(document);
    }
}

public class Document
{
    [XmlElement]
    public int id { get; set; }

    [XmlElement]
    public string name { get; set; }
}

---

I want it to output like this:
<?xml version="1.0"?>
<Documents xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://mynamespace.com">
<Document>
<id>1</id>
<name>greg</name>
</Document>
<id>2</id>
<name>jeff</name>
<Document>
</Document>
</Documents>

And here's the main part of just creating the document:

Code:

---

Documents myDocs = new Documents();
Document myDoc1 = new Document();
myDoc1.id = 1;
myDoc1.name = "greg";
myDocs.Add(myDoc1);

Document myDoc2 = new Document();
myDoc2.id = 2;
myDoc2.name = "jeff";
myDocs.Add(myDoc2);

// Make call to serialize here...

---

Right now I'm getting an error on the Add method saying it needs a new keyword.

Anyone have any suggestions?

A couple of things.

Your MyDocuments starts it life being null and so the call to Add will create an error becuase MyDocuments is not initialised.

Also, I do believe that XmlSerialisation requires a default constructor in order for it to work and so you should probably put it in explicitly.

Code:

---

[XmlRoot(Namespace = "http://mynamespace.com")]
public class Documents
{
    public Documents()
    {
      //Default Constructor for Xml Serialisation
    }

    [XmlArray]
    [XmlArrayItem(typeof(Document))]
    public ArrayList MyDocuments { get; set; }

    public void Add(Document document)
    {
        if (MyDocuments == null)
        {
            MyDocuments = new ArrayList();
        }
        MyDocuments.Add(document);
    }
}

public class Document
{

    public Document()
    {
      //Default Constructor for Xml Serialisation
    }

    [XmlElement]
    public int id { get; set; }

    [XmlElement]
    public string name { get; set; }
}
