Stream interface to a file on SFTP server in C# SSH.NET

I am connecting to an SFTP server using SSH.NET and trying to read an image into a stream for displaying it in my web page.
SftpClient client = connectToServer(IP,user,pwd);
string remotePath = client.WorkingDirectory.ToString() + dto.Directory + "/";
FileStream fs = new FileStream(remotePath + dto.FileName,FileMode.Open);
Stream strm = fs;
The above code throws an invalid characters exception. I am not sure if the reason for it is because of the filename on the server i.e. all these files are stored with * delimiter i.e. Text1*Text2*Text3.00.png.
If it is, is there any other way to read the stream?
I have also tried to read from HttpResponse.OutputStream but that throws a read/seek invalid exception.
HttpResponse response = HttpContext.Current.Response;
Stream strm = response.OutputStream;
Are there any other ways to read such image files?
This is the working code code for the same functionality using FtpWebRequest.
var request = (FtpWebRequest)WebRequest.Create(serverUri);
request.UsePassive = true;
request.UseBinary = true;
request.Credentials =//
request.Method = WebRequestMethods.Ftp.DownloadFile;
response = (FtpWebResponse)await request.GetResponseAsync();
Stream responseStream = response.GetResponseStream();
I am changing it to SFTP using SSH.NET.
Is there a way to get the same output as GetResponseStream() with SSH.NET?

If you need to obtain Stream API to a file on SFTP server, use SSH.NET SftpClient.Open[Read]:
Stream fs = client.OpenRead(remotePath);

How can i use/display a file content uploaded to ipage ftp in my weebly site?

This is the code i'm using to upload a simple text file to my ipage.com ftp:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using System.Net;
namespace ScrollLabelTest
{
class FtpFileUploader
{
static string ftpurl = "ftp://ftp.newsxpressmedia.com";
static string filename = #"c:\temp\test.txt";
static string ftpusername = "newsxpressmediacom";
static string ftppassword = "*****";
static string value;
public static void test()
{
try
{
// Get the object used to communicate with the server.
FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(
ftpurl + "/" + Path.GetFileName(filename));
request.Method = WebRequestMethods.Ftp.UploadFile;
// This example assumes the FTP site uses anonymous logon.
request.Credentials = new NetworkCredential(ftpusername, ftppassword);
// Copy the contents of the file to the request stream.
StreamReader sourceStream = new StreamReader(#"c:\temp\test.txt");
byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
sourceStream.Close();
request.ContentLength = fileContents.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
Console.WriteLine("Upload File Complete, status {0}", response.StatusDescription);
response.Close();
}
catch(Exception err)
{
string t = err.ToString();
}
}
}
}
I see the text file: test.txt on my ipage ftp now. But how can i display on my weebly site the content of the text file i just uploaded ? The ftp in ipage.com is my website domain name ftp account.
I just talked to the help support live chat they told me there is no way to do it.
What i want to do is to upload somehow a text file from my hard drive to my site and display the content of the text file on my site each a minute since the text file is getting update every a minute.
This is what they wrote about the ipage ftp:
You can build your site using Web authoring tools, and then use an FTP program to upload the Web pages to your iPage account.
To access your account using an FTP client, you need to connect to ftp.newsxpressmedia.com with your FTP username and password.
And: newsxpressmedia.com is my website domain on weebly.
I can edit drag and drop and design my site on weebly but how can i display the content of a text file every a minute ?

I know not all but some ftp sites have a "change permissions" setting for each file or folder, if it has that setting then you can change permissions to allow anybody to view the file and just put the direct file location

How can I get file from FTP (using C#)?

Now I know how to copy files from one directory to another, this is really simple.
But now I need to do the same with files from FTP server. Can you give me some example how to get file from FTP while changing its name?

Take a look at How to: Download Files with FTP or downloading all files in directory ftp and c#
// Get the object used to communicate with the server.
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://www.contoso.com/test.htm");
request.Method = WebRequestMethods.Ftp.DownloadFile;
// This example assumes the FTP site uses anonymous logon.
request.Credentials = new NetworkCredential ("anonymous","janeDoe#contoso.com");
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader reader = new StreamReader(responseStream);
Console.WriteLine(reader.ReadToEnd());
Console.WriteLine("Download Complete, status {0}", response.StatusDescription);
reader.Close();
reader.Dispose();
response.Close();
Edit
If you want to rename file on FTP Server take a look at this Stackoverflow question

Easiest way
The most trivial way to download a binary file from an FTP server using .NET framework is using WebClient.DownloadFile.
It takes an URL to the source remote file and a path to the target local file. So you can use a different name for the local file, if you need that.
WebClient client = new WebClient();
client.Credentials = new NetworkCredential("username", "password");
client.DownloadFile(
"ftp://ftp.example.com/remote/path/file.zip", #"C:\local\path\file.zip");
Advanced options
If you need greater control, that WebClient does not offer (like TLS/SSL encryption, ASCII mode, active mode, etc), use FtpWebRequest. Easy way is to just copy an FTP response stream to FileStream using Stream.CopyTo:
FtpWebRequest request =
(FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.DownloadFile;
using (Stream ftpStream = request.GetResponse().GetResponseStream())
using (Stream fileStream = File.Create(#"C:\local\path\file.zip"))
{
ftpStream.CopyTo(fileStream);
}
Progress monitoring
If you need to monitor a download progress, you have to copy the contents by chunks yourself:
FtpWebRequest request =
(FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.DownloadFile;
using (Stream ftpStream = request.GetResponse().GetResponseStream())
using (Stream fileStream = File.Create(#"C:\local\path\file.zip"))
{
byte[] buffer = new byte[10240];
int read;
while ((read = ftpStream.Read(buffer, 0, buffer.Length)) > 0)
{
fileStream.Write(buffer, 0, read);
Console.WriteLine("Downloaded {0} bytes", fileStream.Position);
}
}

FtpWebRequest FTP download with ProgressBar

C# FTP app uploads to local directory

I've just written a simple FTP console app to upload files on a local server to a remote FTP site. Everything seems to be working fine until it comes to actually transferring the file. For some reason instead of uploading the file to the specified FTP site it stores the entire file locally with no in the Debug folder with no file type and named the same as the ip of the FTP site. I'm thinking that this has something to do with Visual Studio's debugging. Can anybody give me some guidance on this?
Here is the code I'm using to attempt to upload each file in a string array to the FTP site.
private static void Upload(string ftpServer, string userName, string password, string filename)
{
using (var client = new WebClient())
{
client.Credentials = new NetworkCredential(userName, password);
client.UploadFile(ftpServer, "STOR", filename);
}
}

Use this method instead of that one,it worked for me.
//Directory sands for Remote Server Directory ,it must create if dir not exist
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://serverIP/directory/file");
request.Method = WebRequestMethods.Ftp.UploadFile;
request.Credentials = new NetworkCredential ("username","password");
// Copy the contents of the file to the request stream.
StreamReader sourceStream = new StreamReader("testfile.txt");
byte [] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
sourceStream.Close();
request.ContentLength = fileContents.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
response.Close();

Using ftp in C# to send a file

I'm trying to send a file using ftp. I have the following code:
string server = "x.x.x.x"; // Just the IP Address
FileStream stream = File.OpenRead(filename);
byte[] buffer = new byte[stream.Length];
WebRequest request = WebRequest.Create("ftp://" + server);
request.Method = WebRequestMethods.Ftp.UploadFile;
request.Credentials = new NetworkCredential(username, password);
Stream reqStream = request.GetRequestStream(); // This line fails
reqStream.Write(buffer, 0, buffer.Length);
reqStream.Close();
But when I run it, I get the following error:
The requested URI is invalid for this FTP command.
Please can anyone tell me why? Am I using this incorrectly?

I think you need to specify the path and filename you're uploading too, so I think it should be either of:
WebRequest request = WebRequest.Create("ftp://" + server + "/");
WebRequest request = WebRequest.Create("ftp://" + server + "/filename.ext");

When I had to use ftp method, I had to set some flags on request object, without it the function did not work:
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ftpPath);
request.KeepAlive = true/false;
request.UsePassive = true/false;
request.UseBinary = xxx;
These flags depend on the server, if you have no access to the server then you cannot know what to use here, but you can test and see what works in your configuration.
And file name is probably missing at the end of URI, so that the server knows where to save uploaded file.
