Functional Programming in C#: Classic Programming Techniques for Modern Projects

SUMMARY

You have seen in this chapter that expression trees cover many different scenarios around the idea of handling code at runtime — whether it is the need to understand and analyze code or create it dynamically. Creating code dynamically is more likely to be relevant to a majority of programmers, and in that area expression trees are today the mechanism of choice, instead of the older approaches using reflection or IL emission — at least as long as the slightly restricted expression tree language coverage is sufficient. For a further example, look at Chapter 16, which demonstrates a technique for object cloning that takes advantage of expression trees for dynamic property access.
