包路径：com.opencsv.CSVReader
类名称：CSVReader
方法名：readAll

CSVReader.readAll介绍

[英]Reads the entire file into a List with each element being a String[] of tokens. Since the current implementation returns a java.util.LinkedList, you are strongly discouraged from using index-based access methods to get at items in the list. Instead, iterate over the list.
[中]将整个文件读入一个列表，每个元素都是一个令牌字符串[]。因为当前的实现返回一个java。util。LinkedList，强烈建议您不要使用基于索引的访问方法来获取列表中的项。相反，迭代列表。
