如何根据GUID查找一个SharePoint对象？下文的作者编写了一个PowerShell脚本来实现：

但如上脚本不对Field对象进行检索，本人对此脚本进行了一些完善，结果如下：
<# .SYNOPSIS FindObjectByGuidInSite.ps1 .DESCRIPTION This script attempts to locate a SharePoint object by its unique ID (GUID) within a site collection. The script first attempts to locate a match by examining webs; following webs, lists/libraries are examined. Finally, individual items within lists and libraries are examined. If an object with the ID is found, information about the object is reported back. .NOTES Original Author: Sean McDonough Revised By: Charles Zhang Last Revision: 15-May-2013 .PARAMETER SiteUrl The URL of the site collection that will be searched .PARAMETER ObjectGuid The GUID that identifies the object to be located .EXAMPLE FindObjectByGuid -SiteUrl http://mysitecollection.com -ObjectGuid 91ce5bbf-eebb-4988-9964-79905576969c #> param ( [string]$SiteUrl = "$(Read-Host 'The URL of the site collection to search [e.g. http://mysitecollection.com]')", [Guid]$ObjectGuid = "$(Read-Host 'The GUID of the object you are trying to find [e.g. 91ce5bbf-eebb-4988-9964-79905576969c]')" ) function FindObject($startingUrl, $targetGuid) { # To work with SP2007, we need to go directly against the object model Add-Type -AssemblyName "Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" # Grab the site collection and all webs associated with it to start $targetSite = New-Object Microsoft.SharePoint.SPSite($startingUrl) $matchObject = $false $itemsTotal = 0 $fieldsTotal = 0 $listsTotal = 0 $searchStart = Get-Date $spWeb = $null $spList = $null $spField = $null Clear-Host Write-Host ("INITIATING SEARCH FOR GUID: {0}" -f $targetGuid) # Step 1: see if we can find a matching web. $allWebs = $targetSite.AllWebs Write-Host ("`nPhase 1: Examining all webs ({0} total)" -f $allWebs.Count) foreach ($spWeb in $allWebs) { $listsTotal += $spWeb.Lists.Count if ($spWeb.ID -eq $targetGuid) { Write-Host "`nMATCH FOUND: Web" Write-Host ("- Web Title: {0}" -f $spWeb.Title) Write-Host ("- Web URL: {0}" -f $spWeb.Url) $matchObject = $true break } $spWeb.Dispose() } # If we don't yet have match, we'll continue with list iteration if ($matchObject -eq $false) { Write-Host ("Phase 2: Examining all lists and libraries ({0} total)" -f $listsTotal) $allWebs = $targetSite.AllWebs foreach ($spWeb in $allWebs) { $allLists = $spWeb.Lists foreach ($spList in $allLists) { $fieldsTotal += $spList.Fields.Count $itemsTotal += $spList.Items.Count if ($spList.ID -eq $targetGuid) { Write-Host "`nMATCH FOUND: List/Library" Write-Host ("- List Title: {0}" -f $spList.Title) Write-Host ("- List Default View URL: {0}" -f $spList.DefaultViewUrl) Write-Host ("- Parent Web Title: {0}" -f $spWeb.Title) Write-Host ("- Parent Web URL: {0}" -f $spWeb.Url) $matchObject = $true break } } if ($matchObject -eq $true) { break } } $spWeb.Dispose() } # If we don't yet have match, we'll continue with list fields if ($matchObject -eq $false) { Write-Host ("Phase 3: Examining all lists field ({0} total)" -f $fieldsTotal) $allWebs = $targetSite.AllWebs foreach ($spWeb in $allWebs) { $allLists = $spWeb.Lists foreach($spList in $allLists) { $allFields = $spList.Fields foreach ($spField in $allFields) { if ($spField.ID -eq $targetGuid) { $spList = $spField.ParentList Write-Host "`nMATCH FOUND: Field" Write-Host ("- Field Name: {0}" -f $spField.Title) Write-Host ("- List Title: {0}" -f $spList.Title) Write-Host ("- List Default View URL: {0}" -f $spList.DefaultViewUrl) Write-Host ("- Parent Web Title: {0}" -f $spWeb.Title) Write-Host ("- Parent Web URL: {0}" -f $spWeb.Url) $matchObject = $true break } } if ($matchObject -eq $true) { break } } if ($matchObject -eq $true) { break } } } # No match yet?
