List

go内置的集合只有数组和切片，有时候我们需要更多高级的数据处理功能，比如：排序、去重、交集、并集、聚合操作时，需要编写非常多的代码才能实现。

List集合提供了50多个数据操作功能，可以完全代替go原生的数组类型。

Dictionary 字典

Dictionary是字典的意思，是go内置类型map的代替者，是一种更加高级的数据操作方案

pageList分页

PageList实质就是在List的基础上，增加了一个RecordCount字段，在分页数据的场景下一般都会使用PageList类型来返回

ListAny集合

collections.ListAny实际就是collections.List[any]
