How to get the path of the subfolder that was "SELECTED" in the listbox by the user and save the file inside

The program I'm creating should take the following steps:

First, the user creates a subfolder to save the projects that have been calculated by the program, according to the image and code below.

When you create a subfolder, for example "EM01_Project of a block 4", it is created within a predefined directory (c: \ evandro \ tad \ "EM01_Project of a block 4")

How do I save a file where the name already set in the code written in C # "Loads.txt" where when the user clicks the "Save" button, as shown below, this command recognizes the path of the subfolder opened or created through the textBox_BootName.Text by the end user as explained in item 2?

usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.IO;usingSystem.Threading.Tasks;usingSystem.Windows.Forms;namespaceTad_Bloco1._0{publicpartialclassNovoBloco:Form{string[]listapasta=Directory.GetDirectories(@"c:\evandro\tad");        

    public NovoBloco()
    {
        InitializeComponent();
    }

    private void NovoBloco_Load(object sender, EventArgs e)
    {

        foreach (string p in listapasta)
            listBox_ListaBlocos.Items.Add(Path.GetFileName(p));

    }

    private void button_Ok_Click(object sender, EventArgs e)
    {          
        string pasta = @"c:\evandro\Tad\" + textBox_NomeBloco.Text;

        if (Directory.Exists(pasta) == false)
        {
            Directory.CreateDirectory(pasta);
            listBox_ListaBlocos.Items.Add(Path.GetFileName(pasta));
            MessageBox.Show("Pasta criada com sucesso!");
        }
        else
            MessageBox.Show("Esta pasta já existe");
    }

    private void button_Cancelar_Click(object sender, EventArgs e)
    {
        this.Close();
    }

    private void listBox_ListaBlocos_SelectedIndexChanged(object sender, EventArgs e)
    {
        textBox_NomeBloco.Text = listBox_ListaBlocos.Text;
    }
  }
}

I find it difficult to formulate this here for you, I did not find the question very clear and it was very specific to the point that it really seems like you're asking the code ready for someone ... well, I did not understand the question but I'll try to some points ....

You can write a txt with this simple command
System.IO.File.WriteAllText ("C: \ example.txt", "content");

If the question is a button on a secondary Form saving a file that is somehow contained in the Primary Form you can try to use a Global variable Defining a variable as "public" let's assume that Form Main should call the Form Example passing it a string ... there is more than one way to do this, I'll try to show you the simplest ...

public class Main : Form
{
    public Main(){
        InitializeComponents();
    }
    public void Button1_Click(object o, EventArgs e){
        Exemplo form = new Exemplo();
        form.Caminho = "C:\Exemplo.bin";//aqui é onde a Form Exemplo salvará
        form.Conteudo = "Conteúdo de Exemplo";//aqui é o conteúdo a salvar...
        form.ShowDialog();
    }  

}
public class Exemplo : Form
{
    public string Caminho;
    public string Conteudo;
    public Exemplo(){
        InitalizeComponents();
    }

    public void Salvar_Click(object o, EventArgs e){
        System.IO.File.WriteAllText(Caminho, Conteudo);
    }

}

Well, I ended up giving it a kissed hand but that's it ... I'd rather pass the argument straight to form, but I think this is easier for you.
