C# Executable Executing directory

Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location)

Not an accurate answer to your question, however I would suggest to have a look at:

Path.GetTempFileName()

Try with Environment.CurrentDirectory This returns the folder of your currently working directory.
