Thread: FTP Class Library?

I'm looking for a FREE FTP library for .NET.

I've found a few that either (a) cost money or (b) stink. All I need is to upload a single file, once per month to MVS, and about the only thing standing in my way of automating this is a .NET FTP class library -- that I really don't want to write myself.

I'm unable to find much that meets your requirements, but maybe you can poke around at this for a while: CodeProject: FTP component written with fully managed code. Free source code and programming help

I have a feeling you might end up either writing your own or rewriting someone elses script, however...

Yeah, I looked at that one and put it into my (b) category. It seems to work, but the documentation is practically non-existent. I just located another possible, with source code, that I'm stepping through now. If it works, I'll post back the link.

Yeah, I figured you had come across that one...every component I looked at was either poorly documented and/or written or cost a few hundred dollars.

If you do end up writing your own, you could post in the Code Samples forum for free

Well, I may be SOL here. While I think I could manage to get this working using FtpWebRequest (tho some blog entries I've found say this can't be done to MVS or OS/400), I need to issue the QUOTE SITE command, which doesn't appear to be supported by FtpWebRequest. Bloody Heck.

I did see an idea to run FTP in it's own process -- tho at the moment I'm considering a batch file and stuffing the FTP command into the console buffer -- ah, welcome to the 1980's.

I was about ready to knuckle down and write something, but took one last look around the net. I came across an open source FTP .NET library here: .NET FTP, FTP .NET, FTP C#, FTP VB, C# FTP, VB FTP that is well documented. I've just now downloaded the source, and will see if it's a good as it first appears to be,

I managed to get a clean compile of this library after only about 20 minutes. I had to make only two minor fixes:
(a) OS/400 support didn't seem to be included. Since I don't care about OS/400, I just removed the references to it.
(b) There were a few deprecated methods from .NET 1.1 that could easily be replaced with .NET 2.0 methods (1-1 replacement in each case). There was some conditional compilation in there for 2.0, but it wasn't complete.

Once I got the clean compile, I included what I needed in my application, and got it to work first time! Total time spent: about 90 minutes.

Highly Recommended
