Question

I’m trying to write XML files.

I’ve got a list of Configuration.

[Serializable]
public class Configuration
{
    public decimal X { get; set; }
    public decimal Y { get; set; }
}

And this is my property.

    [XmlArray("Configurations")]
    [XmlArrayItem("Configuration")]
    public List<Configuration> Configurations { get;set; }

The caller is:

    this.Configurations = new List<Configuration>()
    {
        new Configuration() { X = 1, Y = 10 },
        new Configuration() { X = 10, Y = 100 },
    };

    string filename = "test.xml";

    TextWriter writer = new StreamWriter(filename);
    XmlSerializer serializer = new XmlSerializer(typeof(List<Configuration>));
    serializer.Serialize(writer, this.Configurations));
    writer.Close();

And the output is:

<?xml version="1.0" encoding="utf-8"?>
<ArrayOfConfiguration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Configuration x="1" y="10" />
  <Configuration x="10" y="100" />
</ArrayOfConfiguration>

There’s a way that can generate this XML file?

<?xml version="1.0" encoding="utf-8"?> 
<Configurations>
  <Configuration X="1" Y="10" />
  <Configuration X="10" Y="100" />
</Configurations>

Is there a way to generate them in this way?

Answer 1

Try to use following attributes:

[XmlArray("Configurations")]
[XmlArrayItem("Configuration")]
