Question

我在远程服务器的文件夹中设置了一组excel文件。一台WPF应用程序正在我的本地计算机上运行。现在我想能够查看远程文件夹中的文件并下载。怎么做到这一点？

我可以使用FTP吗？如果可能的话？

提前致谢。：）

有可能。这是一个很好的example。并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

我可以使用FTP访问远程文件夹和文件
