AutoMapper creating nested Object Mappings (original)

Before doing a DTO conversion, use the AutoMapper. But the level of the DTO is too deep, but the official did not provide a good solution for the nested type, so I realized a bit:

Idea: Using recursion and reflection is a good way to avoid manually creating a mapping of nested objects.

Later found in self-test, to filter some of the structure may be a lot of trouble, so they perfected the next, with the second version

The second version has been used and online in some of the services within the company, which is good. Because it does not involve any business information within the company, it is just a simple idea and implementation, so it is posted here for everyone to share.

All code is original, reproduced please indicate the source.

In fact, there is no road, go to the past, is the road.
