title: C# "or" operator
body: <p>I have this code:</p>
  
  <pre><code>if (textBox1.Text == "one" || "two")
  </code></pre>
  
  <p>I have tried to use || and | to add more strings, but it says that it cannot be applied to operands of type "bool" and "string". How can I make this work?
  Thank you.</p>
