仅对 RegexMatch 有效。 一元和二元拆分运算符 一元拆分运算符 (-split <string>) 的优先级高于逗号。 因此,如果向一元拆分运算符提交以逗号分隔的字符串列表,则将仅拆分第一个字符串(第一个逗号之前)。 使用以下模式之一来拆分多个字符串: 使用二元拆分运算符(<string[]> -split <分隔符>) 将所有字符串括...
-split 运算符 使用-regex 选项的 switch 语句 默认情况下,PowerShell 正则表达式不区分大小写。 上面所示的每种方法都有一种不同的方法来强制区分大小写。 对于Select-String,使用CaseSensitive参数。 对于使用正则表达式的运算符,请使用区分大小写的版本:-cmatch、-creplace或-csplit ...

一元-split 运算符拆分由 一元表达式指定的一个或多个字符串,并在一个受约束的 1 维字符串数组中返回其子部分。 它将任何连续的空格字符组视为连续子部分之间的分隔符。 可以使用此运算符的二进制版本(§7.8.4.5) 或其两个变体(§7.8)来指定显式分隔符字符串。
