Question

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace Program
{

    class Program
    {

        public static string *GetExtension*(string cale) //GetExtension is an error
        {
            string fisier, extensie;
            cale = @"D:\dir1\dir2\";
            fisier = @"D:\dir1\dir2\fisier.txt";        

            extensie = Path.GetExtension(fisier);

            System.Console.WriteLine("Extensie: {0} returneaza {1}", fisier, extensie);

            extensie = Path.GetExtension(cale);

            System.Console.WriteLine("Extensie: {0} returneaza {1}", fisier, extensie);
        }
    }
}

I apologize for this amateur post.

I don’t understand the error "Program.Program.GetExtension(string)': not all code paths return a value"

Can anyone tell me what have I done wrong, please?

(oh and fisier means file, cale mean path and extensie mean extension in my language).
Thanks in Advance.

Answer 1

The function is supposed to return a string but you have no return statement

add

return extensie;

before the first }

alternatively if you aren’t wanting a return value and are just wanting the console.writelines simply change public static string to be public static void and then you won’t need a return value
