C# Minor Issue when Iterating through file

October 12, 2022

I have a program that iterates through all files from directories and subdirectories, it’s working smoothly but there is just a minor issue that my brain can’t solve.
The one finding the simplest way to solve it is a genius 🙂

Here is the code :

    int hello(string locat)
    {
        string[] files = Directory.GetFiles(locat);
        string[] dirs = Directory.GetDirectories(locat);
        int cpt = 0;
        
        foreach (var file in files)
        {
            try
            {
                textBox1.AppendText(file+"\r\n");

                cpt++;
                textBox2.AppendText(cpt.ToString()+"\r\n");
            }
            catch { }
        }

        
        foreach (string directory in dirs)
        {
            try
            {
                cpt += hello(directory);
            }
            catch { }
        }

        return cpt;

    }

So the problem is that the output of cpt inside textBox2 have a logic behavior but a behavior that is not adequate for my needs

This is how it looks like :

And I want it to be 1,2,3,4,5,6,7,8,9,…

I tried with EnumerateFiles instead of GetFiles, it was working smoothly too but i got some permissions issue and I’m working on .NET framework for this project

>Solution :

A variation that avoids ref

int hello(string locat, int counter = 0)
{
    string[] files = Directory.GetFiles(locat);
    string[] dirs = Directory.GetDirectories(locat);
        

    foreach (var file in files)
    {
        try
        {
            textBox2.AppendText(file + "\r\n");

            counter++;
            textBox2.AppendText(counter.ToString() + "\r\n");
        }
        catch { }
    }


    foreach (string directory in dirs)
    {
        try
        {
            counter = hello(directory, counter);
        }
        catch { }
    }

    return counter;

}
