title: Fastest way to fill an array with a single value
body: <p>I would like to fill a 2D array with a single value that I have, however, I would like to do it the quickest way possible has the 2D array's length will be a total of 200k+ and over time there will be over 200 of these arrays. I have looked into Buffer.BlockCopy and Array.Copy, however, they both take in arrays as the source/destination, where the only array I have is the destination, with the source being a single value.</p>
  
  <p>What is the fastest way to fill in an array with the source being a single value and not an array?</p>
