title: Which is better for performance? And vs AndAlso
body: <p>When writing an If statement, I've always used <code>And</code> when needed like:</p>
  
  <pre><code>If 1=1 And 2=2 Then
  </code></pre>
  
  <p>The only time I ever used <code>AndAlso</code> is if the second condition will error if the first isnt true like:</p>
  
  <pre><code>If Not IsDbNull(Value) AndAlso Value=2 Then
  </code></pre>
  
  <p>However, recently I've heard that <code>AndAlso</code> is better for performance than <code>And</code> as the second condition is only read when the first is true.</p>
  
  <p>In this case, should I always just use <code>AndAlso</code>?</p>
