C# - CSOM - 将文件上传到 Sharepoint Online 中的子目录

Question

我正在尝试将文件上传到 SharePoint Online，我得到了这个示例代码：

var uploadFile = list
            .RootFolder
            .Folders
            .GetByPath(ResourcePath.FromDecodedUrl("A"))
            .Files
            .Add(newFile);

ctx.Load(uploadFile);
await ctx.ExecuteQueryAsync();

它工作得非常好，所以它周围的一切都可以工作。但显然这个sn-p

var uploadFile = list
            .RootFolder
            .Folders
            .GetByPath(ResourcePath.FromDecodedUrl("A/B"))
            .Files
            .Add(newFile);

ctx.Load(uploadFile);
await ctx.ExecuteQueryAsync();

即使两个目录都存在，也会引发 System.IO.DirectoryNotFoundException。那么如何将文件上传到子目录“B”？

尝试像这样上传文件：

 public static void UploadFile(ClientContext context,string uploadFolderUrl, string uploadFilePath)
{
    var fileCreationInfo = new FileCreationInformation
    {
            Content = System.IO.File.ReadAllBytes(uploadFilePath),
            Overwrite = true,
            Url = Path.GetFileName(uploadFilePath)
    };
    var targetFolder = context.Web.GetFolderByServerRelativeUrl(uploadFolderUrl);
    var uploadFile = targetFolder.Files.Add(fileCreationInfo);
    context.Load(uploadFile);
    context.ExecuteQuery();
}

using (var ctx = new ClientContext(webUri))
{
     ctx.Credentials = credentials;

     UploadFile(ctx,"LibName/FolderName/Sub Folder Name/Sub Sub Folder Name/Sub Sub Sub Folder Name",filePath);   
}
