Question

我有一个Powershell脚本，该脚本读取文件和文件夹信息并将数据添加到数组。

如果存在断点，脚本可以正常运行。断点可以在脚本中的任何位置，一旦到达断点，我就继续执行代码，而不会出现错误。

即使我使用断点之前的行Disabled将断点设置为Get-PSBreakpoint | Disable-PSBreakpoint，代码也可以正确执行。

删除断点后，代码错误“方法调用失败，因为添加到数组时[System.ManagementAutomation.PSObject]不包含名为op_Addition的方法。

这里发生错误

$report += New-Object -TypeName PSObject -Property $props

在这里

$filerec += New-Object -TypeName PSObject -Property $propsfile

这是发生错误的功能

    function ScanDrive([string]$scanpath)
{
    #Scan the drive
    $files = Get-ChildItem -Path $scanpath -Force -Recurse
    $filecount = $files.Count
    $Counter = 0

    #Set up the result array
    $folderRes = @()
    $filesRes = @()

    ForEach ($file in $files)
    {
        $lblInfo.Text = $file.FullName
        $Form.Refresh()
        $Counter++
        [Int]$Percentage = ($Counter/$filecount)*100
        $pbScan.Value = $Percentage
        Write-Debug "Help"
        if ($file.Attributes -eq 'Directory')
        {
            write-host 'This is a folder' + $file.FullName -ForegroundColor DarkGreen
            try
            {

                $acl = Get-Acl -path $file.PSPath
                Write-Host 'ACL' + $acl.Group.ToString()

                    $folderRes += $report
                }
                Write-Host "Folder record count : " + $folderRes.Count.ToString()
            }

        }
        else
        {
            write-host 'This is a file' + write-host $file.FullName -ForegroundColor DarkGreen

            $iname = $file.Name
            $iparent = $file.PSParentPath
            $isize = $file.Length
            $itype = $file.Extension
            $iowner = get-acl $file.FullName
            $owner = $iowner.Owner

            $iatts = $file.Attributes

            $propsfile = [ordered]@{
                        'ID' = ''
                        'Name' = $iname;

                        'LoggedDate' = Get-Date
                        }

                    $filerec += New-Object -TypeName PSObject -Property $propsfile 

                    $filesRes += $filerec
                }
    }

    Write-Host "File record count : " + $filesRes.Count.ToString()

    Return $filesRes,$folderRes

}

您无需添加到$filerec和$report，只需覆盖它们即可（将+=更改为=）：

$filerec = New-Object -TypeName PSObject -Property $propsfile
$report = New-Object -TypeName PSObject -Property $props

当前代码尝试创建一个对象数组，然后将其添加到另一个数组中，这将在$folderRes和$filesRes中创建重复项。

Powershell脚本仅在存在断点的情况下起作用
