title: Initialize two dimension char array with string array
body: <p>I have a syntax issue: the following line is OK:</p>
  
  <pre><code>char[,] board = new char[2, 2] { { '1', '2' }, { '3', '4' } };
  </code></pre>
  
  <p>but if I have a string array and try this:</p>
  
  <pre><code>char[,] board = new char[2, 2] { "12".ToCharArray(), "34".ToCharArray() };
  </code></pre>
  
  <p>It gives me error: CS0846   A nested array initializer is expected.
  What should be the correct syntax as I have long strings and don't use the char syntax in the first sample?</p>
