Console App Task 08: How to get application running path in C#

Console App Task 08: How to get application running path in C# ? 

In C#, you can get the application's running path and append "Output\Log" using the following methods:

---

Method 1: Using AppDomain (Recommended)

using System;
using System.IO;

class Program
{
    static void Main()
    {
        string appPath = AppDomain.CurrentDomain.BaseDirectory;
        string logPath = Path.Combine(appPath, "Output", "Log");

        Console.WriteLine("Application Path: " + appPath);
        Console.WriteLine("Log Path: " + logPath);

        // Ensure directory exists
        Directory.CreateDirectory(logPath);
    }
}

✅ Best for Console & Windows Applications
✅ Gets the path of the executable's directory

---

Method 2: Using Environment.CurrentDirectory

string appPath = Environment.CurrentDirectory;
string logPath = Path.Combine(appPath, "Output", "Log");

✅ Works but may return different paths depending on execution context.

---

Method 3: Using Process.GetCurrentProcess()

using System.Diagnostics;

string appPath = Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName);
string logPath = Path.Combine(appPath, "Output", "Log");

✅ Works even if the app runs as a service

---

Example Output (if the app runs from C:\MyApp\bin\Debug\)

Application Path: C:\MyApp\bin\Debug\
Log Path: C:\MyApp\bin\Debug\Output\Log

---

Final Notes

• Use Directory.CreateDirectory(logPath); to ensure the folder exists before writing logs.
• Use Path.Combine() instead of string concatenation (+) to ensure cross-platform compatibility.
