I don’t have much experience in C#. But I’m trying to understand the code of a program I have here.

Here use the following code: 

foreach(var item in _main.entrada) {
....
}

I want to include _main.saida (along with input) in foreach.... has how to do this?

c# thread foreach

    explain better... the foreach will go through item by item of a collection, of what you are needing ?

Yes, just use the method Union (is in the System.Linq namespace) provided the two collections are of the same type

foreach (var item in _main.entrada.Union(_main.saida))
{
    ...
}

Full example:

public class MainCollection
{
    public int[] entrada;

    public int[] saida;

    public MainCollection()
    {
        entrada = new int[] { 1, 2, 3 };
        saida = new int[] { 4, 5, 6 };
    }
}


public class Program
{
    private static MainCollection _main = new MainCollection();

    public static void Main()
    {
        foreach (var item in _main.entrada.Union(_main.saida))
        {
            Console.WriteLine(item);
        }

        Console.ReadKey();

        return;
    }
}
