title: Copy one 2D array to another 2D array
body: <p>I used this code to copy one 2D array to another 2D array:</p>
  
  <pre><code>Array.Copy(teamPerformance, 0,tempPerformance,0, teamPerformance.Length);
  </code></pre>
  
  <p>However, when I change some data in <code>tempPerformance</code> then these changes also apply to <code>teamPerformance</code>.<br />
  What should I do to control that?</p>
