C# XML Serialization of double[] to single space-delimited element

Question

I am writing an app in C# to serialize and array of double or float to a single XML element that is a space-delimited list of the values in the array.

double[] d = new double[4] { 1.0, 2.0, 3.0, 4.0 };

to the XML element:

<ArrayOfDouble type="double">1.0 2.0 3.0 4.0</ArrayOfDouble>

I am trying to use the XmlSerializer to perform the serialization. Any help on how to get this done simply would be greatly appreciated.

You can try something like the following. My sample uses LINQ. If you are using VS2005 or earlier let me know and I'll update the answer.

class Example {
  [XmlIgnore]
  public double[] DoubleValue { get ... set ... }

  public string ArrayOfDouble {
    get { return DoubleValue.Select(x => x.ToString()).Aggregate( (x,y) => x + " " + y); }
    set { Doublevalue = value.Split(' ').Select(x => Double.Parse(x)).ToArray(); }
  }
}
