如何使 TextBox 中的列表可点击？

Question

I'm doing a phone book in C#, when I click on "affichez tout vos contacts" (print all your contacts), it's print a list of contact in the textbox:

I'd like when I click on "Remi"'s line for example it's open a form, and in this form I get remi's data with costructeur, but I dont know how to get remi's data.

I suppose its Something like this?

private void TBnumero_MouseDoubleClick(object sender, MouseEventArgs e)
{
    Form ModifierEtSupprimer = new Form(Name, Number);ModifierEtSupprimer.Show();
}

But I dont know how to get Name and Number.

Using a ListBox as your control. 1st Add items to listbox:

ListBox phoneBook = new ListBox();
pnoheBook.Items.Add("Remi 741256");
pnoheBook.Items.Add("Khahal 164235");
pnoheBook.Items.Add("thegod 5578");
....

Then register the selection Change Event and pass the selection to new Form:

private void pnoheBook_SelectedIndexChanged(object sender, EventArgs e)
{
    if (pnoheBook.SelectedIndex == -1)
    {
       return;// no selection we exit.
    }         
    var selection = pnoheBook.SelectedValue.ToString().Split(' ');
    Form ModifierEtSupprimer = new Form(selection[0], selection[1]);
    ModifierEtSupprimer.Show();
}
