拆分选择-字符串

Question

给定此变量

$foo = help | Select-String powershell

尝试拆分将失败

PS > $foo.split()
Method invocation failed because [Microsoft.PowerShell.Commands.MatchInfo]
does not contain a method named 'split'.
At line:1 char:1
+ $foo.split()
+ ~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : MethodNotFound

如何拆分这个变量？

Answer 1

匹配行的字符串值位于MatchInfo对象的line属性中。

$foo.Line.split()

Answer 2

Split是一个字符串方法，因此必须在字符串上调用它。

[string] $foo = help | Select-String powershell

或

$foo = help | Select-String powershell | Out-String
