Hi friends,

What's the problem of my code that gives me an error?

C#

public int f()
{
    int x = 8;
        int y = 8;

    PictureBox[,] pic = new PictureBox[8, 8];
    for (int i = 0; i < x; i++)
    {
        for (int j = 0; j < y; j++)
        {
            pic[i, j] = pictureBox34;
            Console.WriteLine(String.Format("[i,j] = [{0},{1},{2}]", i, j));
        }
    }

Hi Arash,

the function you posted isn't complete, but from your compilation error I can see that you're not returning an int in some code paths.
This means that further down in your fucntion you have some if statments
and there are return statements in some but not all branches.
And for sure there is no return statment right before the closing brace of the function definition.

If I need to do more explaining, please feel free to post a comment to this answer.

Cheers,

Manfred

Your method returns an int

public int f()

So, it has to return a value

C#

public int f()
{
    int x = 8;
        int y = 8;
    PictureBox[,] pic = new PictureBox[8, 8];
    for (int i = 0; i < x; i++)
    {
        for (int j = 0; j < y; j++)
        {
            pic[i, j] = pictureBox34;
            Console.WriteLine(String.Format("[i,j] = [{0},{1},{2}]", i, j));
        }
    }

    return x; // what do you want to return??
}

If you don't need a return value, use void

public void f()
