如何创建不可变数组?

问题描述

我想在 Powershell 中创建一个(不可变的)元组(或数组)元素，所以我的尝试如下:

I want to create an (immutable) tuple (or array) of elements in Powershell, so my attempt is the following:

$t = @("A","B")

现在，这将创建一个我可以添加到的数组:

Now, this creates an array that I can add to:

$t += "C"

我希望 $t 在程序执行期间是不可变的.我该怎么做?

I want $t to be immutable during the execution of the program. How can I do this?

推荐答案

你实际上可以使用元组

PS[1] (203) > $t = [tuple]::create(1,2,3)
PS[1] (204) > $t.item1
1
PS[1] (205) > $t.item1 = 4
'item1' is a ReadOnly property.
At line:1 char:1
+ $t.item1 = 4
+ ~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : PropertyAssignmentException
