加入分隔符忽略

Question

我試圖在PowerShell中創建一個數組，然後將它加入到單個字符串中。這是我的代碼：

$solutionRoot = "c:\temp" 
$libraryPaths = @(
    $solutionRoot + "\a", 
    $solutionRoot + "\b" 
) 

$joined = ($libraryPaths -join ",") 
$joined 

$joined2 = [string]::Join(",", $libraryPaths) 
$joined2 

然而，輸出是：

c:\temp\a c:\temp\b 
c:\temp\a c:\temp\b 

和有我的路徑（所希望的輸出是c:\temp\a,c:\temp\b）之間沒有分隔符。

我在做什麼錯？

Answer 1

你並沒有真正從$libraryPaths開始。 試試這個：

$solutionRoot = "c:\temp" 
$libraryPaths = @(
    ($solutionRoot + "\a"), 
    ($solutionRoot + "\b") 
) 

$joined = ($libraryPaths -join ",") 
$joined 

$joined2 = [string]::Join(",", $libraryPaths) 
$joined2 

Answer 2

或者只是：

$libraryPaths = @(
    "$solutionRoot\a", 
    "$solutionRoot\b" 
)
