title: I need very big array length(size) in C#
body: <pre><code>public double[] result = new double[ ??? ];
  </code></pre>
  
  <p>I am storing results and total number of the results are bigger than the 2,147,483,647 which is max int32. </p>
  
  <p>I tried biginteger, ulong etc. but all of them gave me errors.</p>
  
  <p>How can I extend the size of the array that can store > 50,147,483,647 results (double) inside it?</p>
  
  <p>Thanks...</p>
