Question

I’m trying to get the variable result from a foreach in my main method. The code looks like this:

    static void Main(string[] args)
    {

        ArrayList lines = GetLines("test.txt", "8394", true);
        foreach (string s in lines)
        {
            string result = s;
        }
        Console.WriteLine(result);
    }

As you can see it returns an error because I cannot access the variable outside of the foreach.
How do I access it?

I cannot understand what do you want to achieve… but the code should be this:

 ArrayList lines = GetLines("test.txt", "8394", true);
 string result=string.Empty;       
 foreach (string s in lines)
        {
            result = s;
        }
        Console.WriteLine(result);

I think you want do to something like this:

 ArrayList lines = GetLines("test.txt", "8394", true);

 foreach (string s in lines)
        {
           Console.WriteLine(s);
        }
