powershell - 将select的结果转换为数组

Question

我有以下代码。

$l = @("A", "B", "X", "Y")
echo "A,B,X`n1,2,3,4" > .\myFile # Create test file

$f = cat myFile | ConvertFrom-Csv | gm -MemberType NoteProperty | select Name
compare $l $f

$a = .... # convert $f to array
compare $l $a

如何转换 $f到数组以便可以与数组进行比较？支撑 @(...)不起作用。

比较 $l 时我得到以下结果和 $f .

PS C:\Users\nick> compare $l $f

InputObject                                                 SideIndicator
-----------                                                 -------------
@{Name=A}                                                   =>
@{Name=B}                                                   =>
@{Name=X}                                                   =>
A                                                           <=
B                                                           <=
X                                                           <=
Y                                                           <=

替换 select Name与 select -Expand Name或 ForEach-Object { $_.Name } .
