Drag file OUT of application

Member 9940802 asked:

There are tons of examples about how to receive a drag/drop event into a control in a C# application. However, I need to send data OUT of my application via drag/drop.

Specifically, I have a DataGridView that lists a set of files. The files can be anything - Excel, Word, BMP, you name it and my application allows the user to import it, and see a list of what's been imported.

I need for the user to be able to drag a file out of my DataGridView and into another (external) application. I have all the basic code in place to do the drag/drop (right now it is sending a file path as a String), but I can't figure out how to wrap the actual file data into the correct object form for the DoDragDrop event.

Currently, I write the selected files to a TMP folder on drag/drop initiation, so the reference is to an actual file on disk. However, I have the binary for each file stored in a database, so it is perfectly acceptable if the solution takes data directly from the database.
