What does "Object reference not set to an instance of an object" mean?
<pre><code>string[] splitstr = 
            this.strArraylist1[this.comboBox1.SelectedIndex].Split(delimeter, 5);
this.textBox4.Text = splitstr[1];
</code></pre>

<p>At this statement I'm getting the error:</p>

<blockquote>
  <p>Object reference not set to an
  instance of an object</p>
</blockquote>
