Creating SFTP or FTP user account through c# code

Question

Is this possible to create sftp users by my code? I'm using bitvise SSH server as my sftp server, and filezilla server as my ftp server, now I want to create different users for my different customers so that they all would have access of different folders on my server and could not be able to access each others path (folders). I can use either of them (sftp or ftp), but my priority is sftp. Can anyone have some idea of user creation either in sftp or in ftp by c# code?

Answer 1

For FileZilla server, you can modify C:\Program Files (x86)\FileZilla Server\FileZilla Server.xml (FileZillaServer/Users) and have the server reload the config using:

"FileZilla Server.exe" /reload-config

Answer 2

I got the solution and here I'm posting it. It would be helpful for someone else in future:

try
{
    string hely = @"C:\Program Files (x86)\FileZilla Server\FileZilla Server.xml";
    StreamWriter wr = new StreamWriter(hely, false);
    wr.WriteLine("<FileZillaServer>");
    wr.WriteLine("      <Settings>");
    wr.WriteLine("       <Item name=\"Admin port\" type=\"numeric\">14147</Item>");
    wr.WriteLine("   </Settings>");
    wr.WriteLine("  <Groups />");
    wr.WriteLine("  <Users>");
    wr.WriteLine(" <User Name=\"test\">");
    wr.WriteLine("      <Option Name=\"Pass\">test</Option>");
    wr.WriteLine("       <Option Name=\"Group\"></Option>");
    wr.WriteLine("      <Option Name=\"Bypass server userlimit\">0</Option>");
    wr.WriteLine("       <Option Name=\"User Limit\">0</Option>");
    wr.WriteLine("      <Option Name=\"IP Limit\">0</Option>");
    wr.WriteLine("     <Option Name=\"Enabled\">1</Option>");
    wr.WriteLine("      <Option Name=\"Comments\">test</Option>");
    wr.WriteLine("      <Option Name=\"ForceSsl\">0</Option>");
    wr.WriteLine("   <IpFilter>");
    wr.WriteLine("      <Disallowed />");
    wr.WriteLine("      <Allowed />");
    wr.WriteLine("  </IpFilter>");
    wr.WriteLine("  <Permissions>");
    wr.WriteLine("       <Permission Dir=\"D:\\FTP_Root\">");
    wr.WriteLine("      <Option Name=\"FileRead\">1</Option>");
    wr.WriteLine("     <Option Name=\"FileWrite\">1</Option>");
    wr.WriteLine("       <Option Name=\"FileDelete\">1</Option>");
    wr.WriteLine("       <Option Name=\"FileAppend\">1</Option>");
    wr.WriteLine("       <Option Name=\"DirCreate\">1</Option>");
    wr.WriteLine("      <Option Name=\"DirDelete\">1</Option>");
    wr.WriteLine("      <Option Name=\"DirList\">0</Option>");
    wr.WriteLine("      <Option Name=\"DirSubdirs\">1</Option>");
    wr.WriteLine("      <Option Name=\"IsHome\">1</Option>");
    wr.WriteLine("       <Option Name=\"AutoCreate\">0</Option>");
    wr.WriteLine("    </Permission>");
    wr.WriteLine("  </Permissions>");
    wr.WriteLine("<SpeedLimits DlType=\"0\" DlLimit=\"10\" ServerDlLimitBypass=\"0\" UlType=\"0\" UlLimit=\"10\" ServerUlLimitBypass=\"0\">");
    wr.WriteLine("              <Download />");
    wr.WriteLine("          <Upload />");
    wr.WriteLine("       </SpeedLimits>");
    wr.WriteLine(" </User>");
    wr.WriteLine("  </Users>");
    wr.WriteLine("</FileZillaServer>");
    wr.Close();
    string pathtofilezilla = @"C:\Program Files (x86)\FileZilla Server";
    Process.Start("CMD.exe", "/C \"" + pathtofilezilla + "\\FileZilla Server.exe\" /reload-config");
}
catch (Exception ex)
{
    throw ex;
}
