Question

我正在尝试在powershell中组合字符串以生成文件路径。我正在学习基础知识，并将这种语法放在一起

$fileDirectory = "C:\Pics\"

foreach ($file in Get-ChildItem $fileDirectory){
    #Setting parent dir to check
    $ParentDir = "E:\Main Folder\"

    #setting param to split
    $parts =$file.Name -split '\.'

    #capturing variables
    $PictureYear = $parts[0].Trim()
    $PictureMonth = $parts[1].substring(0,3)

    #Writing To window to confirm variables are accurate
    Write-Host $PictureYear
    Write-Host $PictureMonth

    #checking if folders exist
    Write-Host $($ParentDir)$($PictureYear)\
}

但是当我Write-Host时，文件路径中有一个空格。输出是

E:\Main Folder\ 2016 \

如何删除空格？我尝试使用Trim()运算符，但空格仍然存在。

不要破坏你的泡泡，但已经有一个cmdlet和.Net方法来组合路径：

Join-Path -Path $ParentDir -ChildPath $PictureYear
$ParentDir | Join-Path -ChildPath $PictureYear | Join-Path -ChildPath $PictureMonth

[System.IO.Path]::Combine($ParentDir, $PictureYear, $PictureMonth)

$parts = @($ParentDir) + $parts  # array of all components    
[System.IO.Path]::Combine([string[]]$parts)

Powershell添加空间
