C#- arrays - exception error

See more:

C#

This line throws IndexOutOfRangeException(index was outside the bounds of array) and it is pointed on this line in the code:

names[i] += txtName.Text + "\r\n";

This happens only if I stop entering names(lets say after entering few of them and after hitting show names button, I get the list that I entered. But when I continue entering name again, I get the exception error?

So if I continue entering names upto 100 without hitting show names in the middle, no error. I should be able to contunie add names after hitting the show names as long as it is not beyond 100 names.

Any ideas why?

<pre lang="C#">namespace Arrays
{
    public partial class frmMain : Form
    {
        public frmMain()
        {
            InitializeComponent();
        }



        //initialize the Array
        string[] names = new string[100];

        int i = 0;


        //Enter  Names up to 100 and store them in array
        private void btnEnterName_Click(object sender, EventArgs e)
        {

            names[i] += txtName.Text + "\r\n";

            txtName.Clear();

        }



        //Display stored Names in Array using foreach loop in multiline textbox
        private void btnShowNames_Click(object sender, EventArgs e)
        {
            foreach (var item in names)
            {

                txtNames.Text += names[i] + "\r\n";

                i++;


            }

        }

    }
}

What I have tried:

tried i++ after the line where error is pointed but no success.
