您可以使用的FtpWebRequest ;但是，这是相当低的水平。有一个较高级别的类 Web客户端，该需要少得多的$ C $下很多场景;但是，默认情况下不支持FTP / SSL。幸运的是，你可以通过注册自己的preFIX使用FTP / SSL的Web客户端的工作：

You can use FtpWebRequest; however, this is fairly low level. There is a higher-level class WebClient, which requires much less code for many scenarios; however, it doesn't support FTP/SSL by default. Fortunately, you can make WebClient work with FTP/SSL by registering your own prefix:

private void RegisterFtps()
{
    WebRequest.RegisterPrefix("ftps", new FtpsWebRequestCreator());
}

private sealed class FtpsWebRequestCreator : IWebRequestCreate
{
    public WebRequest Create(Uri uri)
    {
        FtpWebRequest webRequest = (FtpWebRequest)WebRequest.Create(uri.AbsoluteUri.Remove(3, 1)); // Removes the "s" in "ftps://".
        webRequest.EnableSsl = true;
        return webRequest;
    }
}

一旦你这样做，你可以使用的WebRequest几乎就像正常的，只是你的URI以FTPS：//，而不是FTP：//。一个需要注意的是，你必须指定方法，因为不会有一个默认的。例如，

Once you do this, you can use WebRequest almost like normal, except that your URIs start with "ftps://" instead of "ftp://". The one caveat is that you have to specify the method, since there won't be a default one. E.g.

// Note here that the second parameter can't be null.
webClient.UploadFileAsync(uploadUri, WebRequestMethods.Ftp.UploadFile, fileName, state);
