title: c# - Replace Text in ListBox
body: <p>How would I say, detect specific text in a listbox and replace it with specific text.
  Eg:</p>
  
  <pre><code>        private void timer1_Tick(object sender, EventArgs e)
      {
          if(listBox1.Text.Contains("Hi"))
          {
              // replace with Hello
          }
      }
  </code></pre>
