Question

我正在试图找出原因，我的Get-ChilddItem变量在运行下面的scriptblock时返回一个空的$ null值，而从ISE，如果我手动输入变量值，我就能得到一个我在Get-ChildItem命令之前选择的.sql文件的输出。下面是我写的函数的开头：

Function test{ 
[CmdletBinding()]
Param (
   [Parameter(Mandatory=$True]
   [string]$client
   )
# Define variables
$Master = 'master'
$Slave = 'slave'
$SourcePath = "C:\somefolder\folder"
$Masterfolder = "C:\somemasterfolder"
$Slavefolder = "C:\someslavefolder"

# Create folders
    $clientdir2 = New-Item -Path $Slavefolder -name "$client" -ItemType    Directory

# Create folder on secondary server
    $clientdir = New-Item -Path "Microsoft.PowerShell.Core\FileSystem::\\$master\somemasterfolder" -name "$client" -ItemType Directory

# Getting all sql files and copy them to the destination folder
    $gflz = Get-ChildItem $SourcePath\* -Include __07*, __08*, __10*
# Copy
    Copy-Item $gflz $clientdir2

# Replace values in each sql files 
    $cpz = @(Get-ChildItem $clientdir2\* -Include *.sql)
if ($cpz -ne $null) {               
    Foreach ($flz in $cpz) {
        (Get-Content $flz.FullName) | ForEach-Object { $_ -replace'clientID', "$client" -replace 'C:\LSpath', `
        "$Masterfolder" -replace'C:\LSPath2', "$Slavefolder" } | Set-Content $flz.FullName}}

因此，不能进行替换操作，因为它不会循环。我是否以错误的方式为预期目的写这个？你能指出我正确的方向吗？谢谢！

从Stackoverflow帖子PowerShell Script to Find and Replace for all Files with a Specific Extension中找出我的问题。我非常确定Get-Content $sqlfiles | gm -MemberType Properties TypeName: System.String Name MemberType Definition ---- ---------- ---------- PSChildName NoteProperty System.String PSChildName=Mysqlfiles.sql PSDrive NoteProperty System.Management.Automation.PSDriveInfo PSDrive=C PSParentPath NoteProperty System.String PSParentPath=C:\parentpath PSPath NoteProperty System.String PSPath=mysqlfilefullpathname.sql PSProvider NoteProperty System.Management.Automation.ProviderInfo PSProvider=Microsoft.PowerShell.Core\FileSystem ReadCount NoteProperty System.Int64 ReadCount=1 Length Property int Length {get;}命令中的files属性包含 Fullname 或 Name 作为成员。事实证明，当我检查成员时，我无法获得任何属性匹配FullName或Name：

user defined data formats

所以与FullName属性相关的唯一属性是 PSPath ，正如我在上面引用的帖子中所建议的那样。定义正确的属性最终有助于替换每个文件中的字符串，就像我期望的那样。致Daniel Liuzzi和Robben_Ford_Fan_boy的提示。
