    SPSolution solution = SPFarm.Local.Solutions.Add("http://centraladmin/Deployment List/MySolution.wsp");

Well you didn't specify an error, but I am guessing it doesn't know what you are talking about when you give it that url.

When you deploy to SharePoint it expects a physical file in a physical location.

I had a similar problem trying to parse the contents of .doc files from the old 2003 Office library.

We ended up downloading the file to the filesystem, processing it, then deleting it from the filesystem. The same would work here and you would maintain the transparency you are looking for.

Download the file to the server filesystem

Deploy the file

Delete the file from the filesystem

  • Seems like a nice approach for overcoming the constraint of having to specify a physical path for the file. Commented Apr 20, 2013 at 13:42

Your code does not work as the Solution.Add method expects a System.IO.Path, not a Uri. You need to specify a valid Path (UNC, local path, etc.) when using Solution.Add("path").
