将数组中的文件名与文件结构中的文件进行比较

Question

$folder = filestructure
# Get a recursive list of all folders beneath the folder supplied by the operator
$AllFolders = Get-ChildItem -Recurse -Path $Folder |? {$_.psIsContainer -eq $True}

# Get a list of all files that exist directly at the root of the folder
# supplied by the operator
$FilesInRoot = Get-ChildItem -Path $Folder | ? {$_.psIsContainer -eq $False}
Foreach ($File in ($FilesInRoot))
{
    #Notify the operator that the file is being uploaded to a specific location
    if($Global:successfullymigrated -contains $File){
        Write-Host $File
    }
}

###this part doesn't work
foreach($CurrentFolder in $AllFolders)
{
    # Set the FolderRelativePath by removing the path of the folder supplied 
    # by the operator from the fullname of the folder

    $FolderRelativePath = ($CurrentFolder.FullName).Substring($Folder.Length)
    $FileSource = $Folder + $FolderRelativePath
    $FilesInFolder = Get-ChildItem -Path $FileSource | ? {$_.psIsContainer -eq $False}

    # For each file in the source folder being evaluated, call the UploadFile 
    # function to upload the file to the appropriate location
    Foreach ($File in ($FilesInFolder))
    {
        Write-Host $File
        if($Global:successfullymigrated -contains $File){
            Write-Host $File
        }
    }
}

我上面的代码应该通过文件结构并检查是否有任何文件名在数组中（这是一个包含文件名的字符串数组）。我的代码适用于根文件，打印出数组中的所有文件，但是当我们检查根以外的其他文件夹中的文件时，它不起作用。即使它输出文件结构中的文件。我完全卡住了。

如果我有误解，请原谅我，但我看了这篇文章

My code above is supposed to go through a file structure and checks to see if any of the file names are in the array

并解释为您只是在寻找与您提供的名称列表完全匹配的文件的文件路径。

所以我有这个示例应该可以做到这一点。

$Global:successfullymigrated = @("template.txt","winmail.dat")
$folder = "C:\temp"
Get-ChildItem $folder -recurse | Where-Object{$Global:successfullymigrated -contains $_.Name -and !$_.psIsContainer} | Select-Object -ExpandProperty FullName

您应该能够将其合并到您自己的代码中。它输出匹配文件的完整路径。我的例子有根和子结构的输出文件。

C:\temp\winmail.dat
C:\temp\docs\template.txt

!$_.psIsContainer 是为了确保我们不会在结果中返回文件夹。如果您有 PowerShell 3.0 或更高版本，则可以将其替换为 Get-ChildItem

的 -File 开关
