在 SharePoint 2013 中以编程方式创建文件夹

目前我有在中创建文件夹的代码Documents运行时目录：

using (var context = new Microsoft.SharePoint.Client.ClientContext(sharePointSite))
{
    context.Credentials = new Microsoft.SharePoint.Client.SharePointOnlineCredentials(user, password);

    Web web = context.Web;

    Microsoft.SharePoint.Client.List docs = web.Lists.GetByTitle(<upper level folder>);
    docs.EnableFolderCreation = true;

    docs.RootFolder.Folders.Add(folderName);

    context.ExecuteQuery();

    return true;
}

我在使用此代码创建的文件夹中创建子文件夹时遇到问题。就像我想创建一个名为的文件夹一样Feb under Documents这会做到这一点。但如果我想创建一个名为Week 2在新文件夹下Feb。它不会那样做。我收到此错误：

{"List 'Feb' does not exist at site with URL 'https://my.sharepoint.com/sites/labels'."}

我意识到问题可能是docs.RootFolder.Folders.Add(folderName);因为Feb不会是根文件夹，当它查找它时，会抛出异常。

因此，我希望有人可以帮助我编写一些代码，将子文件夹添加到已创建的文件夹中。我正在使用 Visual Studios 2010，无法升级到 2012，否则我会升级到 2012。我有2013年的Microsoft.Sharepoint.Client可以在VS 2010中引用的dll。

如何在 SharePoint 2010/2013 中通过 CSOM 创建文件夹（包括嵌套）

/// <summary>
/// Create Folder client object
/// </summary>
/// <param name="web"></param>
/// <param name="listTitle"></param>
/// <param name="fullFolderUrl"></param>
/// <returns></returns>
public static Folder CreateFolder(Web web, string listTitle, string fullFolderUrl)
{
    if (string.IsNullOrEmpty(fullFolderUrl))
        throw new ArgumentNullException("fullFolderUrl");
    var list = web.Lists.GetByTitle(listTitle);
    return CreateFolderInternal(web, list.RootFolder, fullFolderUrl);
}

private static Folder CreateFolderInternal(Web web, Folder parentFolder, string fullFolderUrl)
{
    var folderUrls = fullFolderUrl.Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries);
    string folderUrl = folderUrls[0];
    var curFolder = parentFolder.Folders.Add(folderUrl);
    web.Context.Load(curFolder);
    web.Context.ExecuteQuery();

    if (folderUrls.Length > 1)
    {
        var subFolderUrl = string.Join("/", folderUrls, 1, folderUrls.Length - 1);
        return CreateFolderInternal(web, curFolder, subFolderUrl);
    }
    return curFolder;
}

Usage

 using (var ctx = new ClientContext("https://contoso.onmicrosoft.com/"))
 {
       ctx.Credentials = new Microsoft.SharePoint.Client.SharePointOnlineCredentials("username", "password");
       var folder = CreateFolder(ctx.Web, "Shared Documents", "FolderA/SubFolderA/SubSubFolderA");
 }

如何获取文件夹客户端对象

public static Folder GetFolder(Web web, string fullFolderUrl)
{
    if (string.IsNullOrEmpty(fullFolderUrl))
        throw new ArgumentNullException("fullFolderUrl");

    if (!web.IsPropertyAvailable("ServerRelativeUrl"))
    {
        web.Context.Load(web,w => w.ServerRelativeUrl);
        web.Context.ExecuteQuery();
    }
    var folder = web.GetFolderByServerRelativeUrl(web.ServerRelativeUrl + fullFolderUrl);
    web.Context.Load(folder);
    web.Context.ExecuteQuery();
    return folder;
}

Usage

var existingFolder = GetFolder(ctx.Web, "Shared Documents/FolderA/SubFolderA/SubSubFolderA");
