无法使用命名空间反序列化XmlArray

Question

I have the following XML:

    <MovieRunTimes>
      <ShowDate>6/9/2012</ShowDate>
      <ShowTimesByDate xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
        <a:string>12:25</a:string>
        <a:string>17:30</a:string>
        <a:string>22:35</a:string>
      </ShowTimesByDate>
      <TicketURI>http://www.fandango.com/tms.asp?t=AANCC&amp;m=112244&amp;d=2012-06-09</TicketURI>
    </MovieRunTimes>

And the following C# class:

public class MovieRunTimes
{
    [XmlElement("ShowDate")]
    public string ShowDate { get; set; }

    [XmlElement("TicketURI")]
    public string TicketUri { get; set; }

    [XmlArray("ShowTimesByDate", Namespace = "http://schemas.microsoft.com/2003/10/Serialization/Arrays")]
    public List<string> ShowTimesByDate { get; set; }

}

Unfortunately the ShowTimesByDate is empty after I deserialize. If I remove the namespace from the ShowTimesByDate element and the prefix from the string element, then it deserializes fine. How do I correctly use the namespace to deserialize the XML?

Answer 1

I discovered how to do this. If I amend the class to:

public class MovieRunTimes
{
    [XmlElement("ShowDate")]
    public string ShowDate { get; set; }

    [XmlElement("TicketURI")]
    public string TicketUri { get; set; }

    [XmlArray("ShowTimesByDate")]
    [XmlArrayItem(Namespace = "http://schemas.microsoft.com/2003/10/Serialization/Arrays")]
    public List<string> ShowTimesByDate { get; set; }

}

It deserializes correctly.

The trick is to add a namespace prefix ("a" in your case) to your Collection wrapper element:

<MovieRunTimes >
  <ShowDate>6/9/2012</ShowDate>
  <a:ShowTimesByDate xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
    <a:string>12:25</a:string>
    <a:string>17:30</a:string>
    <a:string>22:35</a:string>
  </a:ShowTimesByDate>
  <TicketURI>http://www.fandango.com/tms.asp?t=AANCC&amp;m=112244&amp;d=2012-06-09</TicketURI>
</MovieRunTimes>

That is how it comes out after serializing with this code:

        XmlSerializer xs = new XmlSerializer(typeof(MovieRunTimes));
        XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
        ns.Add("a", "http://schemas.microsoft.com/2003/10/Serialization/Arrays");
        string result = null;
        using(StringWriter writer = new StringWriter())
        {
            xs.Serialize(writer,mrt,ns);
            result = writer.ToString();
        }
