$myarray = [System.Collections.ArrayList]::new() [void]$myArray.Add('Value') 我们正在调用 .NET 以获取此类型。 在本例中,我们将使用默认构造函数来创建它。 然后调用 Add 方法向其中添加项。我在行首使用 [void] 是为了禁用返回代码。 某些 .NET 调用会这么做,并可能会产生意外输出。如果数组中的唯一...
It isn't easy to delete elements from an array, but you can create a new array that contains only selected elements of an existing array. For example, to create the $t array with all the elements in the $a array except for the value at index position 2, type:PowerShell Copy ...

Modify an existing firewall rule When a rule is created, Netsh and Windows PowerShell allow the administrator to change rule properties and influence, but the rule maintains its unique identifier (in Windows PowerShell this is specified with the -Name parameter). For example, you could have a...
Automatic unraveling can also be confusing in the context of returning an object from a function call. If you would like to return an enumerable object from a function or script, you’ll want to wrap that object in an array using the unary comma operator. ...
