How do I get the icon associated with a file type?

c#, file-association, icons

Solution

CodeProject has some classes you can download.

First get the `FileAssociationInfo`, and from that get the `ProgramAssociationInfo`. The `pai` object can give you the icon.

FileAssociationInfo fai = new FileAssociationInfo(".bob");
ProgramAssociationInfo pai = new ProgramAssociationInfo(fai.ProgID);
ProgramIcon icon = pai.DefaultIcon;

Problem

I have a form that displays file information in a TabControl, and I'd like the pages to have the file's icon in their tab. How do I get the icon associated with a file type? I'd prefer solutions that don't involve looking things up in the registry, but if that's the only way then so be it.
