FTP upload with DotNet

Member Posts: 12
Hi, everyone.
I have created an FTP upload function from within NAV using .NET, so that no external libs are needed for that.
Gladly sharing this with you (not optimized or anything, but works):
Now a question - I can't get my head around this:
The
FTPRequest.Method := 'STOR';
was my lucky guess, and every code sample I've seen actually says:
FTPRequest.Method := WebRequestMethods.Ftp.UploadFile;
As far as I understand, WebRequestMethods.Ftp is a .NET enumeration that in this case corresponds Strings.
How to use these enumerations appropriately?
Disclaimer: This is my first encounter with NAV+.NET

URL := 'ftp://remote_server/remote_folder/testfile.txt';
FTPRequest := WebRequest.Create(URL);
Credentials := Credentials.NetworkCredential('some_login', 'some_password');
FTPRequest.Credentials := Credentials;
FTPRequest.KeepAlive := false;
FTPRequest.UseBinary := true;
FTPRequest.Method := 'STOR';
FTPRequest.UsePassive := true;
FileStream := FileA.OpenRead('c:\testfile.txt');
FTPRequest.GetRequestStream.Write(FileA.ReadAllBytes('c:\testfile.txt'), 0, FileStream.Length);

I wonder if you ever got this working with downloading by ftp?
Thanks to your sharing I was able to get the upload working, but I can't figure out the syntax to make it download.
My attempts shown here:
viewtopic.php?f=32&t=58060
Would really appreciate any advice. This is absolutely a first attempt with anything dotnet for me.
