推荐答案

使用此代码，只需替换用户凭据:

Use this code, just replace the user credentials:

static void Main(string[] args)
{
    FtpWebRequest ftpRequest = (FtpWebRequest)WebRequest.Create("ftp://mywebsite.com/");
    ftpRequest.Credentials = new NetworkCredential("user345", "pass234");
    ftpRequest.Method = WebRequestMethods.Ftp.ListDirectory;
    FtpWebResponse response = (FtpWebResponse)ftpRequest.GetResponse();
    StreamReader streamReader = new StreamReader(response.GetResponseStream());           
    List<string> directories = new List<string>();            

    string line = streamReader.ReadLine();
    while (!string.IsNullOrEmpty(line))
    {
        directories.Add(line);
        line = streamReader.ReadLine();
    }
    streamReader.Close();


    using (WebClient ftpClient = new WebClient())
    {
        ftpClient.Credentials = new System.Net.NetworkCredential("user345", "pass234");

        for (int i = 0; i <= directories.Count-1; i++)
        {
            if (directories[i].Contains("."))
            {

                string path = "ftp://mywebsite.com/" + directories[i].ToString();
                string trnsfrpth = @"D:\Test" + directories[i].ToString();
                ftpClient.DownloadFile(path, trnsfrpth);
            }
        }
    }
