Automapper - 为什么要用Mapper.Initialize？ [英] Automapper - why use Mapper.Initialize?

问题描述

我通常不会问这样的问题就在这里，但遗憾的是虽然 AutoMapper 似乎是一个很好的映射库，它的文档可悲的糟糕 - 没有为库的方法没有XML文档，最官方的在线文档我能找到的这，该非常活跃。如果任何人有任何更好的文档，请让我知道

I wouldn't normally ask this kind of question on here, but unfortunately whilst AutoMapper seems to be a good mapping library, its documentation is woefully bad - there is no XML documentation for the library's methods, and the most official online documentation I could find was this, which is very brisk. If anyone has any better documentation, please let me know.

这是说，这里的问题：为什么要使用 Mapper.Initialize ？它似乎并不如你可以用它来要求 Mapper.CreateMap 立即，并没有文件我不知道是什么初始化是为了做。

That said, here's the question: why use Mapper.Initialize? It doesn't seem to be required as you can just use Mapper.CreateMap immediately, and as there is no documentation I have no clue what Initialize is meant to do.

推荐答案

我问AutoMapper的用户列表中，并且这个答案基本上是说为什么

I asked on the AutoMapper users list, and this answer basically says why:

这件事情做让AutoMapper做确定性（随机）优化。性能方面，它是更好地得到在初始化调用创建了所有的映射。

It's something to do with allowing AutoMapper to do deterministic (stochastic) optimization. Performance-wise, it's better to get all your mappings created in the Initialize call.
