C#如何将(过滤后的)文件列表传递给WebDav.Client并上传该列表上的所有文件？现在我只能把单独的文件

using WebDav.Client;
using WebDav.Client.Exceptions;
using WebDav.Client.Extensions;
using WebDav.Client.Http;
using WebDav.Client.Tasks;

var client = new WebDavClient();
client.Server = new WebDavServer(new Uri("WebDAV服务器URL"));
client.Credentials = new NetworkCredential("用户名", "密码");

string[] files = Directory.GetFiles("文件目录路径", "过滤条件");

foreach (var file in files)
{
    try
    {
        using (var fileStream = File.OpenRead(file))
        {
            var uploadTask = client.UploadFileAsync(fileStream, "上传目录路径/" + Path.GetFileName(file));
            uploadTask.Wait();
        }
    }
    catch (WebDavHttpException ex)
    {
        // 处理上传异常
    }
}
