-contains運算子會檢查集合中是否包含您的值。 一旦找到匹配項目,就會傳回$true。 PowerShell $array=1..6if($array-contains3) {# do something} 這是查看集合是否包含您值的慣用方式。 每次使用Where-Object(或-eq)遍歷整個清單,速度會明顯變慢。
if语句执行的第一步是计算括号中的表达式。 如果计算结果为$true,则执行大括号中的scriptblock。 如果值为$false,则会跳过该脚本块。 在上面的示例中,if语句仅计算$condition变量。 其计算结果为$true,将在脚本块内执行Write-Output命令。 在某些语言中,可以在if语句后放置一行代码,它将会得以执行。 在 PowerSh...

As a result, the $z array contains 1, 3, 5, and 9.To delete an array, assign a value of $null to the array. The following command deletes the array in the $a variable.$a = $nullYou can also use the Remove-Item cmdlet, but assigning a value of $null is faster, especially ...

PowerShell uses the parameter value order to associate each parameter value with a parameter in the function. When you use positional parameters, type one or more values after the function name. Positional parameter values are assigned to the $args array variable. The value that follows the ...

or a character. The endpoints of the range must be convertible to signed 32-bit integers ([int32]). Larger values cause an error. Also, if the range is captured in an array, the size of resulting array is limited to[int]::MaxValue - 56. This is maximum size of an array in .NET...
In that case, just use the –notcontains operator, an operator that returns True if the target value can’t be found in the array. In other words:Copy $arrColors -notcontains "violet" Here’s what we get back:Copy True Why? Because it’s true that the word violet is not an ...
