我可以使用FTP访问远程文件夹和文件

Question

我在远程服务器的文件夹中设置了excel文件。一个WPF应用程序正在我的本地机器上运行。现在我想能够查看远程文件夹中的文件并下载。如何实现这一目标？

我可以使用FTP吗？ 如果可能如何？

在此先感谢。 :)

这是可能的。这是一个不错的example。和msdn documentation。

FileStream outputStream = new FileStream(destinationoffile, FileMode.Create); 
FtpWebRequest request = FtpWebRequest.Create(FTPAddress + "/" + filename) as FtpWebRequest; 
request.Credentials = new NetworkCredential(username, password); 
request.UsePassive = true; 
request.Method = WebRequestMethods.Ftp.DownloadFile; 

FtpWebResponse response = request.GetResponse() as FtpWebResponse; 
Stream responseStream = response.GetResponseStream(); 
long cl = response.ContentLength; 
int bufferSize = 2048; 
int readCount; 
float perc = 0; 
float result = 0; 
float totalread = 0; 
byte[] buffer = new byte[bufferSize]; 
readCount = responseStream.Read(buffer, 0, bufferSize); 
while (readCount > 0) 
{ 
     totalread += readCount; 
     result = totalread/fileSize; 
     perc = result * 100; 
     progress.Value = perc; // this is a progressbar on my screen so may show error for you 
     outputStream.Write(buffer, 0, readCount); 
     readCount = responseStream.Read(buffer, 0, bufferSize); 
} 

responseStream.Close(); 
response.Close(); 
outputStream.Close(); // keeps file open if not closed
