我一直在這工作了幾天,似乎無法弄清楚爲什麼我無法下載目錄中的每個文件我的服務器。在獲得訪問被拒絕錯誤後,我成功地能夠下載第一個文件。使用Renci.ShNet從服務器目錄中下載每個文件
下面是我用來連接到服務器並開始下載過程的代碼。
public void downloadPaperwork()
{
// Setup Credentials and Server Information
ConnectionInfo ConnNfo = new ConnectionInfo(ipAddress, port, serverName,
new AuthenticationMethod[]{
// Key Based Authentication (using keys in OpenSSH Format)
new PrivateKeyAuthenticationMethod(serverName,new PrivateKeyFile[]{
new PrivateKeyFile(keyFile,password)
}),
});
using (var sftp = new SftpClient(ConnNfo))
{
sftp.Connect();
sftp.ChangeDirectory("/var/www/html/invoices");
List<SftpFile> invoices = sftp.ListDirectory(".").ToList();
foreach (var file in invoices)
{
string filename = Path.Combine(Application.StartupPath + folder, file.Name);
using (var fs = new FileStream(filename, FileMode.Create))
{
if(!file.Name.Equals(".") && !file.Name.Equals(".."))
{
MessageBox.Show(file.Name);
sftp.DownloadFile(file.FullName, fs);
fs.Close();
}
}
}
sftp.Disconnect();
}
}
下面是整個例外,在運行時我recive:

我試着將文件添加到文件流,我沒有得到一個錯誤,但它使替換一個文件只留下目錄中的最後一個文件。
任何幫助將不勝感激。提前致謝。
'C:\ Users \ ***** \ Documents \ Visual Studio 2015 \ Projects \ ******** \ ********** \ bin \ Debug \ *** * \ Invoices'是錯誤的地方,它看起來像一個文件夾而不是文件。您需要修改代碼以跳過文件夾(或遍歷文件夾)。 – Icemanind
使用調試器..我確定在第二次迭代時連接仍然打開?嘗試檢查sftp連接狀態。也是在這行'foreach(發票var文件)聲明發票' – MethodMan
我該怎麼做呢? –
