You can use the Unity Properties API to visit .Net objects at runtime. The Properties API is in the Unity.Properties namespace and it uses a visitor design pattern to visit .Net objects at runtime. The visitor pattern is a design pattern that allows you to add new operations to an existing object structure without modifying the structure itself.
