c# - Display different numbers in a textBox

Question

I want to write a code that displays numbers 1 to 10 in a textBox. Following code has been written by me. But unfortunately only number 10 is displayed in textBox. What is wrong in my code? Thanks.

public partial class Form1 : Form
{
    int i,j;

    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        for (i = 1; i <= 10; i++)
        {
            textBox1.Text = Convert.ToString(i);
            for (j = 0; j < 10000000; j++) ;
        }
    }
}

Answer 1

textBox1.Text = Convert.ToString(i);

Overwrites the textbox text each loop. You want:

textBox1.Text += Convert.ToString(i) + " ";

Note, there are others ways of doing this
