从2个文本框中填充列表框

Question

How do you get the text from two textboxes to populate a listbox on a Windows Form Application? I can not get the text that is put into the textboxes to go to the listbox.

This is the code I got so far:

       private void Form1_Load(object sender, EventArgs e)
    {
        if (File.Exists("Contacts.txt"))
        {
            StreamReader Info = new StreamReader("Contacts.txt");
            listBox1.Items.Clear();
            while (Info.EndOfStream != true)
                listBox1.Items.Add(Info.ReadLine());
            Info.Close();
        }
    }


    private void button1_Click(object sender, EventArgs e)
    {

        listBox1.Items.Add(textBox1.Text);
        listBox1.Items.Add(textBox2.Text);
        textBox1.Clear();
        textBox2.Clear();
        Console.WriteLine("/n");
    }

But that Console.WriteLine("/n"); does not put a space between the next entry of the textboxes

You need to call Add() with the Text property of the TextBox not the text box itself. See below.

EDITED: Added way to add the Text to the ListBox and still clear the TextBox controls afterwards.

private void button1_Click(object sender, EventArgs e)
{
    StreamWriter Info = File.AppendText("Contacts.txt");

    string textbox1Content = textbox1.Text;
    string textbox1Content = textbox2.Text;


    listBox1.Items.Add(textbox1Content);
    listBox1.Items.Add(textbox1Content);

    textBox1.Text = String.Empty;
    textBox2.Text = String.Empty;

}

Also I don't understand your for loop... it only executes one time. Whats the point exactly?
