title: Filling an Array with Random numbers, but the rand-Method doesnt work fast enough?
body: <p>I try to fill array by random [-1,0,1] like this, but outputs like that: -1,-1,-1,-1,-1,-1,-1, 0, 0, 0, 0, 0...
  So it changes to slow? Do i have to set a new seed every time?     </p>
  
  <pre><code>Random rnd = new Random();
  
              int z = rnd.Next(2);
              z -= 1;
              int q = rnd.Next(2);
              q -= 1;
  </code></pre>
