Hi.
I am working on a managed dll.
What code can I use in C# to detect if my dll is running under a
service (like IIS) or called from a 'normal' program.
Thanks

Check the value of the System.Environm ent.UserName property. If it is a
non-user account, such as "SYSTEM" or "Network", then it is safe to assume
that the process is running as a service.
Good luck,

That is not necessarily correct because the user could change the identity
that the service is running under.
The problem is that a service is nothing more than an executable. Here are
a couple things that you might try. I have not actually done these but they
make logical sense if you can get them to work.
1) All services inherit from ServiceBase. You might check the call stack
to see if the very first method called belonged to a class that inherited
from ServiceBase.
2) Or you could use the ServiceControll er to get the names of all services
registered in the system and compare them with your application. If there
is a match, you may be running in a service. This is not perfect I guess
since it might be possible to have a service and a regular application with
the same name.

System.Environment.CurrentDirectory and

Any Idea?

Hi,
I need the directory of a running process or service's executable. Any
ideas how to do this?
I looked up some Win APIs but none to accomplish this task.
I noticed there is a .StartInfo.WorkingDirectory in the process object
but it is always empty. I would think that the working dir would be the
same as the EXE if not defined.
