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。

Answer 1

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()

            getallaccountDto customer = null;        
                foreach (DataRow dr in dtData.Rows)
                {
                customer = new getallaccountDto();
                customer.Name = dr["FirstName"].ToString();
                customer.Phone = dr["PhoneNumber"].ToString();
                customer.Balance = dr["Balance"].ToString();
                customer.company = dr["CompanyName"].ToString();
                customer.Email = dr["Email"].ToString();
                customer.CustomerID = dr["CustomerID"].ToString();
                customerList.Add(customer);
