There are a few cases I can see requiring this for:

1. The file is a data file that will likely never change, or only
needs to change when recompiling.  In this case it would be better to
embed the file in the compiled executable as a resource and use
reflection to extract the stream at runtime.

2. The file is a configuration-type file that will probably change.
In this case you can either do what you're doing (which I would not
recommend) or use
Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData),
"YourAppName") to obtain a path to a directory where you can save and
load this stuff.

3. The file is a data file that will be processed by the application.
In this case you should either allow specification of the filename as
an argument, or if you really want to only allow one filename, just
open the file by its name and allow the environment to locate the file
in the current working directory.

And if you really want to approach the problem the way you are, then
you want to "using System.IO; using System.Reflection;" and use
Path.Combine(Path.GetDirectoryName(Assembly.GetEntryAssembly().Location),
"yourdatafilename").
