C# – Getting the current directory in an assembly used by a web service app and windows service

I have an assembly that reads a configuration file which is in the application directory.

This assembly is used from a windows service and a web service.

From the windows service the following works:

string ConfigFile = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "MyFile.config");

However from the webservice, baseDirectory is the directory before the bin directory where the config file is.

So how do I make the assembly find the file for both a windows service and a web service?

Thanks

Why do you not just check if the config file exists in

Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "MyFile.config");

and if it does not you check here:

Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "bin\MyFile.config");

Hopefully I understood the description of the behaviour in the "webservice case" correctly.

Try

System.Reflection.Assembly.GetEntryAssembly().Location

The .NET Assembly loader:

This assembly does not match what was requested and therefore you get this error.

In simple words, it can't find the assembly that was referenced. Make sure it can find the right assembly by putting it in the GAC or in the application path.
