SFTP upload with SSH.NET

upload.cs

const string host = "domainna.me";
const string username = "chucknorris";
const string password = "norrischuck";
const string workingdirectory = "/highway/hell";
const string uploadfile = @"c:\yourfilegoeshere.txt";
 
Console.WriteLine("Creating client and connecting");
using (var client = new SftpClient(host, port, username, password))
{
    client.Connect();
    Console.WriteLine("Connected to {0}", host);
 
    client.ChangeDirectory(workingdirectory);
    Console.WriteLine("Changed directory to {0}", workingdirectory);
 
    var listDirectory = client.ListDirectory(workingdirectory);
    Console.WriteLine("Listing directory:");
    foreach (var fi in listDirectory)
    {
        Console.WriteLine(" - " + fi.Name);
    }
 
    using (var fileStream = new FileStream(uploadfile, FileMode.Open))
    {
        Console.WriteLine("Uploading {0} ({1:N0} bytes)", uploadfile, fileStream.Length);
        client.BufferSize = 4 * 1024; // bypass Payload error large files
        client.UploadFile(fileStream, Path.GetFileName(uploadfile));
    }
}

This code just saved my day!! <3

This needs to be a part of the examples. Why is there no Upload example by default?

@DavidDeSloovere
We are trying to upload files in D:\ drive but, this library only allows to upload files in C:\ and its subdirectories. We have tried, ChangeDirectory() to change the root directory to D:\ which fails with the error - "No such file".
Any thought would be appreciated, on how can we achieve it?

Thanks, helpful!
