如何使用PowerShell修改SharePoint列表中的项目值

Question

如何使用PowerShell修改SharePoint列表中的项目值？当我尝试以下内容时:

$splist.GetItems() | ForEach-Object{
 #Write-Host $_["Item"]

 if($_["Item"] -eq $null){
  $SPFileCollection = $folder.Files
  $upFile=Get-ChildItem D:\Tools\SP-scripts\MDNSO-template.aspx
  $tmpValue = $_["Title"]
  $filename = "EM_Doc_Library\$tmpValue"
  $SPFileCollection.Add("EM_Doc_Library\$tmpValue",$upFile.OpenRead(),$false)
  Write-Host "creating the file"
  Write-Host $_["Title"]
  $_["Item"] = "MDNSO-<$tmpValue>"
 }
}

它说,unable to index into an object of type SPlistItem.

以下是您可以尝试执行的操作的摘要:

$spWeb = Get-SPWeb -Identity http://yourdomain/sites/config
$spList = $spWeb.Lists["AppSettings"]
$spItem = $spList.GetItemById(10013) //or another way that you prefer.
$spItem["Name"] = "MyName"
$spItem.Update()
