我是新使用这种“访客模式”风格，并通过VisitHairDef方法使代码循环出现5次问题。每次此方法循环时，HairDef对象都将被重新创建，随后在将每个循环写入ColonistManager.Population[i].HairDef对象之前，每个循环只存储一条信息。因此，最终结果只有一个变量存储在ColonistManager.Population[i].HairDef中。我不知道为什么这个特定的部分正在循环，并希望有更多的经验的人可以为我提供一些启示。如果需要更多信息，我已将整个源代码上传到Dropbox：https://www.dropbox.com/s/eeq8hwwaoa2ld0b/ColonistCreationMod%20Source.zip
