C#

static string diziKarsilastir(ArrayList a, ArrayList b)
        {
            string[] dizi = new string[4];
            for(int i = 0; i<4; i++)
            {
                if(a[i].ToString() == b[i].ToString())
                {
                    dizi[i] = "true";
                }
                else
                {
                    dizi[i] = "false";
                }
            }
            
            return dizi[];
       
        }

What I have tried:

I want to return the dizi array, but I get an error. (Error CS0443 Syntax error; value expected) When I use for loop ; (
Error CS0161 'Form1.diziKarsilastir(ArrayList, ArrayList)': not all code paths return a value)

You probably have to have the receipt.

Seriously though...

Your method is likely to throw an exception if either of the parameters contain fewer than four elements, or either is null. Your method would never pass a code review, or even pass a reasonably complete unit test.

Medhi Gholam's solution is the answer you're looking for, but I would also refactor the method to be more robust.

Solution 1

dizi is a string[] so your function should be :

C#

static string[] diziKarsilastir(ArrayList a, ArrayList b)
{
...
}

EDIT:
You need to remove the square brackets from the return statement:

C#

return dizi;

Also, your return statement will error - don't include the square brackets. C# doesn't like that. Improving Mehdi's answer to include that.
