如何将元素之间没有空格的数组字符串化？

Question

$readFile = get-content $readInput

#create an empty array to be filled with bank account numbers
$fNameArray = @()

for($i = 0; $i -lt $readFile.length; $i++){

    #assigns a random letter from the list to $letter.
    #$letter = get-random -inputobject ("A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z") -count $readFile.length 
    $letter = $readFile[$i] | foreach-object{get-random -inputobject ("A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z") -count $readFile[$i].length}

    $fnameArray += "$letter"
}
$fnameArray

代码正在读取一个文件，该文件包含一个名称列表并随机化字母以进行数据屏蔽。我运行遇到的唯一问题是输出是这样的：

L R Y E B
R O M I
U Q N G R
H K Y
M G A W Q
J G W Y D K T
X E Q
J Y P I G

看起来是字母之间有空格输出的。我该如何消除它们？

Answer 1

-join 运算符的一元形式连接（串联）所有数组元素，没有分隔符。

> -join ('a', 'b', 'c')
abc

因此，只需使用：

$fnameArray += -join $letter

相比之下，"$letter" 使用 $OFS（输出字段分隔符）作为分隔符对数组进行字符串化，默认为 space，它解释了你的输出。

因此，您也可以将 $OFS 设置为 ''（空字符串）并使用 "$letter"。但是，-join 方法更简单，不需要您为/恢复以前的 $OFS 值创建本地作用域。
