Ephemera

.NET ephemerons

Attach and use properties to objects at run-time which are automatically collected after the host object is collected.

This is accomplished with weak-references, implemented in the ConditionalWeakTable class

Usage

var foo = new Foo();

// Attach some things to `foo`
foo.Fmrn().Set("Name", "Value");
foo.Fmrn().Set("Bar", new Bar());

// Retrieve them
var bar = foo.Fmrn().Get<Bar>("Bar");
var name = foo.Fmrn().Get<String>("Name");

// Retrieve with `TryGet`
var didGetUnsetProperty = foo.Fmrn().TryGet("Nope", out var unset);
