Re: Loading Class Library From FTP Location To Memory

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

The web service is fine, but to clarify, my security concern was that the client machine would let code be executed from a byte array not stored locally.

Thanks for your reply,

You show me a good way but I ll try to do using webservice (returns byte[] array) instead of downloading dll file, cos I ll use dll based authentication and planning my web service accept some parameters (usercode, pass, dllname, etc..) and gives me desired dll as bytearray, every dll will have same method like ( showsomething() ) and main app will call it.

I ll track the logs on my web service side

Thanks for all, researching in progress :)

Well, it looks like your code could use WebClient.DownloadData(url) to get the dll as an array of bytes, then call Assembly.Load(byte []) to load it. I've never tried this though, but it seems possible. I've got to believe there are some security settings that would prevent it though.

After deploying main application using Clickonce,

Is this possible for this dot net application to download a class library from an ftp or http location (as only one dll) and to use it just in memory (I dont like to save it somewhere, just load into memory and use it) ? Next time someome want s to use that class library, will download and use again and again and again.

My purpose is I have a main application and according to the logged user, I ll perform above issue and show a form to user (lots of other forms (class libs) will be available)

Possible ?

Thanks a Lot
