Question

Is it possible to index the value of an Enum instead of its string representation using Solrnet?

Say I have to following enum:

[Serializable]
[Flags] 
public enum Gender
{
  Male = 0,
  Female = 1
}

and add a solr attribute to the Gender property of a User class:

[SolrField("gender")]
public virtual Gender Gender { get; set; }

If I index the entity using:

solr.Add(user)

then it will index ‘Male’ as gender instead of 0. Is it possible to have it index 0 instead?

Edit: I’d prefer not to add an extra property for this, like Ondrej proposes.

You can do this by implementing ISolrFieldSerializer. If the type IsEnum, serialize by casting to int. Otherwise delegate to DefaultFieldSerializer. Use the other field serializers for reference.

Hooking up your field serializer depends on the chosen IoC container, check the container’s documentation.
