在此示例中,PowerShell 会创建一个[ArrayList]来保存写入管道内数组表达式中的结果。 在分配到$results之前,PowerShell 会将[ArrayList]转换为[Object[]]。 字符串加法 字符串是不可变的。 每次相加字符串实际上会创建一个足以容纳左操作数和右操作数的内容的新字符串,然后系统将这两个操作数的元素复制
数组末尾的两个元素外的所有元素: 1 2 3 3 通过Sort-Object可以给数组元素排序。 $A=(@(2,3,1,5,4)|Sort-Object)Write-Host$A 输出如下: 1 2 3 4 5 2.ArrayList ArrayList的大小可动态调整,在处理大量需要添加或删除的数据时性能十分优越。 在数组前加上[System.Collections.ArrayList]即为ArrayList,例...
