Question

我正在使用SharePointPnP模块我试图从位于一个列表下的每个文档中提取一些属性信息我目前面临的一个问题是第29行的属性 $ Item.UniqueID 它抛出一个异常，因为UniqueID的返回值是$ null 但是，当我进入我的脚本并在Powershell控制台 $ Item 中运行以下命令时，我会获得密钥及其值的属性列表，包括UniqueID !!!

我的问题是，为什么我在每个项目中迭代时获得$ null值？

这是我的powershell脚本：

try
{
    Connect-PnPOnline -Url 'https://SomeCompany.sharepoint.com/FOA/BD/' -Credentials O365

    $Items = Get-PnPListItem -List 'Budget' | Where-Object{$_.FileSystemObjectType -eq 'File'}
    $ItemsFieldValues = $Items.FieldValues | Where-Object {$_.FileDirRef -like '*Models' -and $_.Title -like '*.xlsx' -and $_.Title -like '*-*'}
    $dtItems = New-Object System.Data.DataTable
    $dtItems.Columns.Add("ID", "Int64") | Out-Null
    $dtItems.Columns.Add("OperatingUnit","String") | Out-Null
    $dtItems.Columns.Add("HotelName","String") | Out-Null
    $dtItems.Columns.Add("Title", "String") | Out-Null
    $dtItems.Columns.Add("FileLeafRef", "String") | Out-Null
    $dtItems.Columns.Add("FileDirRef", "String") | Out-Null
    $dtItems.Columns.Add("UniqueID", "Guid") | Out-Null
    $dtItems.Columns.Add("ModifiedBy", "String") | Out-Null
    $dtItems.Columns.Add("ModifiedOn", "String") | Out-Null
    $dtItems.PrimaryKey =$dtItems.Columns[0]

    ForEach($Item in $ItemsFieldValues)
    {
        $TimeStamp = Get-Date -Format s
        $NewRow = $dtItems.NewRow()
        $NewRow.ID = $Item.ID
        $NewRow.OperatingUnit = $Item.Title.Split('-')[0]
        $NewRow.HotelName = ($Item.Title.Split('-')[1]).Split('.')[0]
        $NewRow.Title = $Item.Title
        $NewRow.FileLeafRef = $Item.FileLeafRef
        $NewRow.FileDirRef = $Item.FileDirRef
        $NewRow.UniqueID = $Item.UniqueID #$Item.UniqueID return value is $null
        $NewRow.ModifiedBy = $Global:CurrentUserName
        $NewRow.ModifiedOn = $TimeStamp
        $dtItems.Rows.Add($NewRow)
    }

    if($dtItems.Rows.Count -gt 0)
    {
        $SQLConnection.Open()
        $BulkCopy = New-Object("Data.SqlClient.SqlBulkCopy") $SQLConnection
        $BulkCopy.DestinationTableName = "[Models].[HotelsModels]"
        $BulkCopy.WriteToServer($dtItems)
    }
}

catch
{
    $ErrorLog = "Error On " + (Get-Date) + ";$($_.Exception.Message) - Line Number: $($_.InvocationInfo.ScriptLineNumber)"
    Write-Error "$($_.Exception.Message) - Line Number: $($_.InvocationInfo.ScriptLineNumber)"
    $NewRow = $Global:dtErrorLog.NewRow()
    $NewRow.TimeStamp = [System.datetime]::Now
    $NewRow.ErrorLog = $ErrorLog
    $Global:dtErrorLog.Rows.Add($NewRow)
    Save-ErrorLog
}
Finally
{
    $SQLConnection.close()
}

谢谢

UniqueID 必须是区分大小写的这是正确的脚本

 $NewRow.UniqueID = $Item.UniqueId

由于

SPO Document UniqueID返回值为null
