格式列表:按名称对属性进行排序 [英] Format-List: sort properties by name

问题描述

是否可以通过属性名称对Format-List cmdlet的输出进行排序?
假设我有一个带有两个属性"A"和"B"的对象$ x，当我用它运行Format-List时，我得到了

Is it possible to sort the output of the Format-List cmdlet by property name?
Suppose that I have an object $x with two properties "A" and "B", and when I run Format-List with it I get

(PS) > $x | Format-List
B : value b
A : value a

我想拥有

(PS) > $x | Format-List 
A : value a
B : value b

注意:我应该从一开始就指定，与具有"A"和"B"属性的示例不同，我要处理的真实对象具有很多属性，并且将来可能会添加新的，所以我不知道所有的属性名称.

NOTE: I should have specified from the beginning that, unlike in the example with "A" and "B" properties, the real object I have to deal with has quite a lot of properties, and new ones could be added in the future, so I don't know all the property names in advance.

推荐答案

AFAIK，Format-List不提供此类选项.

AFAIK, Format-List does not provide such an option.

对于您的特定示例，这应该可行:

For your particular example this should work:

$x | Select-Object A, B | Format-List

如果属性集不固定/未知，则使用Get-Member和某些预处理为Select-Object排序参数数组的过程将更加棘手.

If the property set is not fixed/known then the procedure will be more tricky with use of Get-Member and some preprocessing making sorted parameter array for Select-Object.

在这里(让我们用$ host代替$ x):

Here it is (let's use $host instead of $x):

$host | Select-Object ([string[]]($host | Get-Member -MemberType Property | %{ $_.Name } | Sort-Object)) | Format-List

克里斯托弗是正确的，Select-Object不是绝对需要的:

Christopher is right, Select-Object is not absolutely needed:

$host | Format-List ([string[]]($host | Get-Member -MemberType Property | %{ $_.Name } | Sort-Object))
