Answer 1

and what is the problem?
so far it looks like you are just asking to write for you
1. Create a form in the studio
2. Add a textBox and a button
3. When you click on the button, take text from the textBox and look for an entry in the list of predefined (or user-entered) strings
So far, nothing complicated
UPD : based on the fact that you have a sheetBox (it is more convenient), a textBox and a button, it turns out that this code

public Form1()
    {
      InitializeComponent();
    }

    private void button2_Click(object sender, EventArgs e)
    {
      string search = textBox2.Text;
      int index = listBox1.Items.IndexOf(search);
      listBox1.SelectedIndex = index;
    }
  }
