F# Serialization of Record types

Question

I know how to serialize in F# using mutable objects, but is there a way to serialize/deserialize using record types using either XmlSerializer or the DataContractSerializer? loo

Answer 1

You can use this series of annotations on the properties of classes to format the XML:

[XmlRoot("root")]
[XmlElement("some-element")]
[XmlAttribute("some-attribute")]
[XmlArrayAttribute("collections")]
[XmlArrayItem(typeof(SomeClass), ElementName = "item")]

I use the attributes on my c# classes, but deserialize in F# (c# classes are ina referenced lib).

in f#:

use file = new FileStream(filePath, FileMode.Open)
let serializer= XmlSerializer(typeof)
let docs = serializer.Deserialize file :?> SomeClass
