Can C# signals be connected to a setter?

Instead of making a new function I’ve tried using a property’s setter function in a Godot Signal callback

    Godot.Collections.Array sigParams = new Godot.Collections.Array();
    sigParams.Add(false);
    LifespanTimer.Connect("timeout", this, nameof(PropName), sigParams);

However, this is throwing the error

E 0:00:01:0790   Error calling method from signal 'timeout': 'Node2D(SceneFile.tscn)::PropName': Method not found.
  <C Source>     core/object.cpp:1239 @ emit_signal()

So I guess I need a new function, unless there’s another name for these setter functions.
