如何将两个C＃批注组合到“快捷方式”批注中？

Question

In Unity, I've found it's a handy pattern to declare inspector variables (set by reflection or magic by Unity) as private and to annotate them with the [SerializeField] attribute. This keeps programming interfaces clean while allowing the Inspector to set the fields. I also use Resharper, and to let it know that these field are set implicitly I use the attribute [UsedImplicitly(ImplicitUseKindFlags.Assign)] .

This leaves me with a lot of variables as a brick wall of annotations where finding the variables takes unnecessary effort:

[SerializeField, UsedImplicitly(ImplicitUseKindFlags.Assign)]
private Transform headingLabel;
[SerializeField, UsedImplicitly(ImplicitUseKindFlags.Assign)]
private Transform coolDataLabel;
[SerializeField, UsedImplicitly(ImplicitUseKindFlags.Assign)]
private GameObject yetAnotherLabelToMakeThePoint;

How can I combine these annotations into a single annotation [PrivateInspectorVariable] with identical behavior?

Via this answer on Stack Overflow:

However there is nothing in the standard tools that will take two attribute instances and make one.

(In theory a post processor that re-wrote the MSIL could do this.)

My suggestion would be to write your attributes on separate lines and use space to make them easier to read:

[SerializeField]
[UsedImplicitly(ImplicitUseKindFlags.Assign)]
private Transform headingLabel;

[SerializeField]
[UsedImplicitly(ImplicitUseKindFlags.Assign)]
private Transform coolDataLabel;

[SerializeField]
[UsedImplicitly(ImplicitUseKindFlags.Assign)]
private GameObject yetAnotherLabelToMakeThePoint;
