Question

我有一个现有的系统，我们正在清理数千个文档库并将内容移动到Azure中。我正在寻找一种编程方式来迭代列表以找到空的并删除它们。有没有人有任何样本（最好使用CSOM或powershell）来实现他们愿意分享的样本？

此时，我已经提出以下代码来完成任务，但是我收到错误＆＃34;底层连接已关闭：接收时出现意外错误＆＃ 34;尝试加载由于超时导致的列表，因为我有这么多列表。到目前为止，我的解决方案隐藏了uid，pws，site的用户秘密。

var cred = new SharePointOnlineCredentials(uid, pws);
var context = new ClientContext(site);
context.Credentials = cred;
context.RequestTimeout = Timeout.Infinite;

var lists = context.Web.Lists;
context.Load(lists);
context.ExecuteQuery();
foreach(var list in lists)
{
    list.DeleteObject();
    list.Update();
}

Answer 1

尝试下面的代码，这里要做的就是指定要忽略的列表，已经列出了一些系统列表，确保您没有从SharePoint中删除重要内容。

下面的脚本使用SharePoint Online命令行管理程序和PnP PowerShell，在运行脚本之前先下载并安装它们：

https://www.microsoft.com/en-us/download/details.aspx?id=35588 https://github.com/SharePoint/PnP-PowerShell

cls

$url = "https://YOUR-URL-GOES-HERE.sharepoint.com"

if ($cred -eq $null)
{
    $cred = Get-Credential
    Connect-PnPOnline $url -Credentials $cred
}

$CSOM_context = New-Object Microsoft.SharePoint.Client.ClientContext($url)
$CSOM_credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($cred.UserName, $cred.Password)
$CSOM_context.Credentials = $CSOM_credentials

$lists = $CSOM_context.Web.Lists
$CSOM_context.Load($lists)
$CSOM_context.ExecuteQuery()

$ignoreList = "Form Templates", "Site Assets", "Style Library", "_catalogs/hubsite", "Translation Packages"    

$lists  | ? { $_.ItemCount -eq 0 -and $_.BaseTemplate -eq 101 -and $_.Title -inotin $ignoreList}  | % {

    Write-Host "- " $_.Title -NoNewline

    try {
        Remove-PnPList -Identity $_.Title -Force 

        Write-Host -ForegroundColor Green "   [deleted] "  `n  
    }
    catch [Execption] {
        Write-Host -ForegroundColor Red   "   [FAILURE] - " $_.Exception.Message `n  
    }
}

我不认为您需要在此处进行任何超时，您可以使用以下代码删除空文档库

using Microsoft.SharePoint.Client;
using System;
using System.Linq;
using System.Security;

namespace DeleteAllEmptyDocumentLibrary
{
    class Program
    {
        static void Main(string[] args)
        {
            ListItemCollection itemCollection = null;
            SecureString pswd = new SecureString();
            try
            {
                // Site Url to scan  
                string webUrl = "https://SiteUrl";
                string userName = "UserName";
                string password = "Password";
                using (ClientContext context = new ClientContext(webUrl))
                {

                    foreach (char c in password.ToCharArray())
                        pswd.AppendChar(c);
                    // Setting credential for the above site  
                    context.Credentials = new SharePointOnlineCredentials(userName, pswd);
                    context.ExecuteQuery();
                    var lists = context.LoadQuery(context.Web.Lists.Where(l => l.BaseType == BaseType.DocumentLibrary));
                    context.ExecuteQuery();
                    foreach (List list in lists)
                    {
                        try
                        {
                            // Getting all items from selected list using caml query  
                            itemCollection = list.GetItems(CamlQuery.CreateAllItemsQuery());
                            //Loading selected list items  
                            context.Load(itemCollection);
                            context.ExecuteQuery();
                            // Looping each item  
                            if (itemCollection != null && itemCollection.Count == 0)
                            {
                                list.DeleteObject();
                                context.ExecuteQuery();
                            }
                        }
                        catch (Exception ex)
                        { }

                    }
                }
            }
            catch (Exception ex) { }
        }
    }
}
