我必须将文件传输到我创建了shared文件夹的另一台PC。我可以访问此共享文件夹，因为另一台PC通过 LAN 电缆连接。
现在我想使用C＃将文件传输到shared文件夹。我正在关注this link的教程。
代码MWE：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace FileTransferApplication
{
class ftp
{
private string host = null;
private string user = null;
private string pass = null;
private System.Net.FtpWebRequest ftpRequest = null;
private System.Net.FtpWebResponse ftpResponse = null;
private System.IO.Stream ftpStream = null;
private int bufferSize = 2048;
static void Main()
{
ftp ftpClient = new ftp(@"ftp://X.X.0.20/", "dst username", "dst pc password");
/* Upload a File */
ftpClient.upload(@"shared\test.txt", "E:/SampleFile2.txt");
ftpClient = null;
}
/* Construct Object */
public ftp(string hostIP, string userName, string password) { host = hostIP; user = userName; pass = password; }
/* Upload File */
public void upload(string remoteFile, string localFile)
{
try
{
/* Create an FTP Request */
ftpRequest = (System.Net.FtpWebRequest)System.Net.FtpWebRequest.Create(host + "/" + remoteFile);
/* Log in to the FTP Server with the User Name and Password Provided */
ftpRequest.Credentials = new System.Net.NetworkCredential(user, pass);
/* When in doubt, use these options */
ftpRequest.UseBinary = true;
ftpRequest.UsePassive = true;
ftpRequest.KeepAlive = true;
/* Specify the Type of FTP Request */
ftpRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile;
/* Establish Return Communication with the FTP Server */
ftpStream = ftpRequest.GetRequestStream();
/* Open a File Stream to Read the File for Upload */
System.IO.FileStream localFileStream = new System.IO.FileStream(localFile, System.IO.FileMode.Open);
/* Buffer for the Downloaded Data */
byte[] byteBuffer = new byte[bufferSize];
int bytesSent = localFileStream.Read(byteBuffer, 0, bufferSize);
/* Upload the File by Sending the Buffered Data Until the Transfer is Complete */
try
{
while (bytesSent != 0)
{
ftpStream.Write(byteBuffer, 0, bytesSent);
bytesSent = localFileStream.Read(byteBuffer, 0, bufferSize);
}
}
catch (Exception ex) { Console.WriteLine(ex.ToString()); }
/* Resource Cleanup */
localFileStream.Close();
ftpStream.Close();
ftpRequest = null;
}
catch (Exception ex) { Console.WriteLine(ex.ToString()); }
return;
}
}
}
PS：我使用的是Windows-7。
UPDATE-1：实际上我已经共享了用于测试目的的文件夹，因为我还处于学习阶段以传输文件。但我的实际要求是使用IP地址，用户名和密码将文件传输到服务器/ PC。
问题：我正在第二台PC上运行Filezilla ftp服务器。我已经使用User创建了password alogn。我在可以共享的目录中添加了shared文件夹。现在，我收到了一个错误
System.Net.WebException: The remote server returned an error: (530) Not logged in.
代码行ftpStream = ftpRequest.GetRequestStream();
