例如,你可以使用下面的语句将文本中指定的字符串替换成目标文本: -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: 第三类i...
"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。

Example 6: Select unique strings using the `-CaseInsensitive` parameter This example uses case-insensitive comparisons to get unique strings from an array of strings. PowerShell "aa","Aa","Bb","bb"|Select-Object-Unique-CaseInsensitiveaa Bb ...
