Some time ago, I needed to know the pathname of my running application, in order to create a temporary file.
As it seems ther are alot more options than I thought.
So I applied all I could find in this little snippet.
I also used the full names to make clear where everything is coming from.
Guess I'll stick to System.Environment.CurrentDirectory; :)
Let me know if you know others.
Enjoy!

namespace DirectoryTest
{
    class Program
    {
        static void Main(string[] args)
        {
            List<string> DirNames = new List<string>();
           
            // To get the directory name with the exe file:
            //"C:\\Users\\. . .\\Projects\\DirectoryTest\\bin\\Debug\\DirectoryTest.exe"
            DirNames.Add("-------------- + exe");
            DirNames.Add(System.Reflection.Assembly.GetExecutingAssembly().Location); //exe shows as exe
            DirNames.Add(System.Reflection.Assembly.GetExecutingAssembly().CodeBase); //exe shows as EXE
            DirNames.Add(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase); //exe shows as EXE
            DirNames.Add(System.Reflection.Assembly.GetEntryAssembly().Location);
            DirNames.Add(new Uri(Assembly.GetEntryAssembly().CodeBase).LocalPath);

            
            // Give directory names (working directory of executable):
            //"C:\\Users\\. . .\\Projects\\DirectoryTest\\bin\\Debug\\"
            DirNames.Add("-------------- WD");
            DirNames.Add(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase));
            DirNames.Add(new System.IO.FileInfo(Assembly.GetExecutingAssembly().Location).DirectoryName);
            DirNames.Add(System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location));
            DirNames.Add(System.IO.Directory.GetCurrentDirectory());
            DirNames.Add(System.Environment.CurrentDirectory);
            DirNames.Add(System.AppDomain.CurrentDomain.BaseDirectory);
            //string appl = System.Windows.Forms.Application.StartupPath;
            System.IO.DirectoryInfo di2 = new DirectoryInfo("DirectoryTest.exe");
            DirNames.Add(di2.FullName);


            DirNames.Add("-------------- process");
            // To get the directory with name of process file:
            //"C:\\Users\\. . .\\Projects\\DirectoryTest\\bin\\Debug\\DirectoryTest.vshost.exe"
            DirNames.Add(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName);           
            DirNames.Add(Environment.GetCommandLineArgs()[0]);
            

            foreach (var item in DirNames)
            {
                Console.WriteLine(item); 
            }
            Console.ReadKey();
        }
    }
