String对象衍生自string类在控制台输入[String]::然后按Tab键会自动智能提示,这些方法就是String类命令。 Get-Member会返回所有string对象的方法,可以通过参数只返回静态方法,也就是string类命令。使用几率最高的自然Format方法,但是因为PowerShell中已经有了大书特书的-F操作符了,Format方法可以秒杀了。但是Join和Contac...
<string[]> -like <wildcard-expression> <string[]> -notlike <wildcard-expression> <string[]> -match <regular-expression> <string[]> -notmatch <regular-expression> 當這些運算子的輸入是純量值時,它們會傳回 布爾 值。當輸入是值的集合時,集合中的每個項目都會轉換成字串以進行比較。 -...
"book" -ireplace "B", "C" # Case insensitive "book" -creplace "B", "C" # Case-sensitive; hence, nothing to replace Output 复制 Cook book 从PowerShell 7.2 开始,当 -replace 运算符语句中的左侧操作数不是字符串时,该操作数将转换为字符串。 PowerShell 执行不区分区域性的字符串转换。

In this case we’re using the .Net Framework’s System.String class (that’s what the syntax[string]indicates). We then call the static method (indicated by the two colons, ::)Compare, passing the method three parameters: the two strings we want to compare ($a and $b) and the Boole...

Bydefault, PowerShell’s comparison operators are case-insensitive. To use the case-sensitive versions, prefix them with the characterc: -ceq,-cne,-cge,-cgt,-cin,-clt,-cle,-clike,-cnotlike,-cmatch,-cnotmatch,-ccontains,-cnotcontains ...

-replace操作符有三种实现方式,其它文本操作符也类似地有三种实现方式,像-replace,-ireplace,-creplace,i前缀表示字符串大小写不敏感(insensitive),c前缀表示字符串大小写敏感(case sensitive)。 #下面的例子没有完成替换,因为当前大小写敏感: “Hello Carl” -creplace “carl”, “eddie” ...
