【问题描述】：
我已经使用 Filezilla 创建了一个 ftp 服务器。我正在尝试使用 c# 代码上传单个文件。我的 cide 是一个非常简单的函数，叫做上传：
static void UploadFile(string filepath)
{
string m_FtpHost = "http://ip:port/";
string m_FtpUsername = "userID";
string m_FtpPassword = "pass";
// Get an instance of WebClient
WebClient client = new System.Net.WebClient();
// parse the ftp host and file into a uri path for the upload
Uri uri = new Uri(m_FtpHost + new FileInfo(filepath).Name);
// set the username and password for the FTP server
client.Credentials = new System.Net.NetworkCredential(m_FtpUsername, m_FtpPassword);
// upload the file asynchronously, non-blocking.
client.UploadFileAsync(uri, "STOR", filepath);
}
static void Main(string[] args)
{
UploadFile("file.pdf");
Console.ReadKey();
}
在 Filezilla 服务器 gui 中，我收到以下消息：
(000017)11/23/2015 10:47:19 AM - (not logged in) (ip)> STOR /file.pdf HTTP/1.1

知道这里可能有什么问题吗？ 编辑：我尝试在 UploadFile 中使用 ftp 更改 http。现在我收到以下信息：
(000019)11/23/2015 10:59:53 AM - chrathan user (ip)> 257 "/" is current directory.
(000019)11/23/2015 10:59:53 AM - user (ip)> TYPE I

(000019)11/23/2015 10:59:53 AM - user (ip)> disconnected.
EDIT2：基本上我尝试访问的文件夹是网络共享磁盘。当我更改为我的电脑中的本地文件夹时，一切正常。最后我的问题是如何访问网络共享磁盘？
【问题讨论】：
-
如何将 WebRequest 与 WebRequestMethods.FTP.Put 一起使用？似乎登录过程不起作用。服务器请求您的授权凭据，答案是 Content-Type，因此，请使用正确的上传请求

我将 http 更改为 ftp，我现在收到新的错误消息。
