列出 Sharepoint 在线文档库中的所有文件答案

【问题标题】：List all files in a Sharepoint online Document Library列出 Sharepoint 在线文档库中的所有文件
【发布时间】：2019-02-09 21:05:10
【问题描述】：

我正在尝试列出 Sharepoint 文档列表中的所有文件，

但是我无法找到访问文档库内容列表的方法，

我能够打印 Sharepoint 包含的所有列表的名称，但不能打印文档库中的文件，

这是我的示例代码：

private static void FList(ICredentials credentials)
{
    ClientContext ctx = new ClientContext(" SHAREPOINT ADDRESS");
    ctx.Credentials = credentials; 

    List doclib = ctx.Web.Lists.GetByTitle("Reporting Rosters"); 
    ctx.Load(ctx.Web.Lists);
    ctx.ExecuteQuery();

    foreach (var list in ctx.Web.Lists)
    {
        Console.WriteLine(list.Title);
    }

结果是 Sharepoint 列表的列表，如果有人可以指导我如何在 sharepoint 文档库中公开文件名，我将不胜感激

这里是实际遍历 Files 、子文件夹和这些子文件夹中的文件的代码

var credentials = new SharePointOnlineCredentials(username, securedPassword);
private static void Flist3(ICredentials credentials)
    {

        ClientContext clientContext = new ClientContext("SHAREPOINT ADDRESS");
        clientContext.Credentials = credentials;  // passing credentials in case you need to work with Sharepoint Online
        using (clientContext)
        {
            List list = clientContext.Web.Lists.GetByTitle("Document Library Name");
            CamlQuery camlQuery = new CamlQuery();
            camlQuery.ViewXml = @"<View Scope='Recursive'><Query></Query></View>";
            Folder ff = list.RootFolder;
            FolderCollection fcol = list.RootFolder.Folders; // here you will save the folder info inside a Folder Collection list
            List<string> lstFile = new List<string>();
            FileCollection ficol = list.RootFolder.Files;   // here you will save the File names inside a file Collection list 
            // ------informational -------
            clientContext.Load(ff);
            clientContext.Load(list);
            clientContext.Load(list.RootFolder);
            clientContext.Load(list.RootFolder.Folders);
            clientContext.Load(list.RootFolder.Files);
            clientContext.ExecuteQuery();
            Console.WriteLine("Root : " + ff.Name + "\r\n");
            Console.WriteLine(" ItemCount : " + ff.ItemCount.ToString());
            Console.WriteLine(" Folder Count : " + ff.Folders.Count.ToString());
            Console.WriteLine(" File Count : " + ff.Files.Count.ToString());

            Console.WriteLine(" URL : " + ff.ServerRelativeUrl);
            //---------------------------
            //---------Here you iterate through the files and not the folders that are in the root folder ------------
            foreach (ClientOM.File f in ficol)
            {
                Console.WriteLine("Files Name:" + f.Name);
            }
            //-------- here you will iterate through the folders and the files inside the folders that reside in the root folder----
            foreach (Folder f in fcol)
            {
                Console.WriteLine("Folder Name : " + f.Name);
                clientContext.Load(f.Files);
                clientContext.ExecuteQuery();
                FileCollection fileCol = f.Files;
                foreach (ClientOM.File file in fileCol)
                {
                    lstFile.Add(file.Name);
                    Console.WriteLine(" File Name : " + file.Name);

                }

}

这是否处理多级文件夹层次结构？

【解决方案2】：

您需要遍历 ListItemCollection 而不是 ListCollection。

为此，您需要使用 CAML 查询获取列表中的所有项目，然后对其进行迭代。

所以，修改你的代码如下：

List doclib = ctx.Web.Lists.GetByTitle("Reporting Rosters"); 
ctx.Load(doclib);
ctx.ExecuteQuery();

Microsoft.SharePoint.Client.CamlQuery camlQuery = CamlQuery.CreateAllItemsQuery();
ListItemCollection listItems = doclib.GetItems(camlQuery);
clientContext.Load(listItems);
clientContext.ExecuteQuery();

foreach (var listItem in listItems)
{
    Console.WriteLine(listItem["FileLeafRef"].ToString());  // gives the file name
    Console.WriteLine(listItem["FileRef"].ToString());  // gives the file's server relative URL
}

你可以试试这个：

    ClientContext cxt = new ClientContext("SHAREPOINT ADDRESS");
    List doclib = cxt.Web.Lists.GetByTitle("Reporting Rosters");

    cxt.Load(doclib);
    cxt.Load(doclib.RootFolder);
    cxt.Load(doclib.RootFolder.Folders);
    cxt.Load(doclib.RootFolder.Files);
    cxt.ExecuteQuery();
    FolderCollection fol = doclib.RootFolder.Folders;
    List<string> listFile = new List<string>();
    foreach(Folder f in fol)
    {
        if (f.Name == "filename")
        {
            cxt.Load(f.Files);
            cxt.ExecuteQuery();
            FileCollection fileCol = f.Files;
            foreach (File file in fileCol)
            {
                listFile.Add(file.Name);
            }
        }
    }
