C#, Cycle through TextBlock on button press, So close
<p>So I am working in C#, bit of a beginner, I have searched around but cannot find anything.</p>

<p>I have a TextBlock on my screen and a Button, each time the button is pressed I want the new text to be the content of the TextBlock, this is what I have so far however it only shows the last line, thanks. </p>

<pre><code> string[] arr = new string[4]; 
        arr[0] = "Hello and Welcome";               
        arr[1] = "To the new app";             
        arr[2] = "enjoy your stay";             
        arr[3] = "press next to continue";          

        for (int i = 0; i &lt; arr.Length; i++)
        {
            string s = arr[i];
            tbArray.Text = s;
        }
</code></pre>
