How to get execution directory of console application

I tried to get the directory of the console application using the below code,

Assembly.GetExecutingAssembly().Location

but this one gives me where the assemble resides. This may be different from where I executed the application.

My console application parses logs with no parameters. It must go to the logs/ folder inside of the executable's folder or if I give it a path to logs/ it parses it.

If google takes in here in 2024 using dotnetcore 8.0, the current way is

System.AppContext.BaseDirectory

Scott Hanselman has a blog post with the following:

using System;
using System.Diagnostics;
using System.IO;
 
namespace testdir
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine($"Launched from {Environment.CurrentDirectory}");
            Console.WriteLine($"Physical location {AppDomain.CurrentDomain.BaseDirectory}");
            Console.WriteLine($"AppContext.BaseDir {AppContext.BaseDirectory}");
            Console.WriteLine($"Runtime Call {Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName)}");
        }
    }

which he uses in .NET Core 3.1, however, I'm running .NET 4.8 and it's working for me.

Here is a simple logging method

using System.IO;
private static void logWrite(string filename, string text)
{
    string filepath = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location) + "\\" + filename;

    using (StreamWriter sw = File.AppendText(filepath))
    {
        sw.WriteLine(text);
        Console.WriteLine(text);
    }
}

Usage:

logWrite("Log.txt", "Test");

Safest way:

string temp = Path.GetDirectoryName(Assembly.GetExecutingAssembly().CodeBase);

Use this :

System.Reflection.Assembly.GetExecutingAssembly().Location

Combine that with

System.IO.Path.GetDirectoryName if all you want is the directory.

Use Environment.CurrentDirectory.

Gets or sets the fully qualified path of the current working directory.
(MSDN Environment.CurrentDirectory Property)

string logsDirectory = Path.Combine(Environment.CurrentDirectory, "logs");

If your application is running in c:\Foo\Bar logsDirectory will point to c:\Foo\Bar\logs.
