title: How to sort a 2D array filld with random numbers
body: <p>I'm doing a class assignment,<br>
  I need to create an 2D array of random numbers and sort them either bubble or other sorting codes. I'm fine with single array, but the problem is a 2D array filled with random numbers, I just don't get it. 
  Random numbers should be made of (-I,I) interval it's a user input. Sorry for bad english, haven't gotten any degree. In working on visual C# windows form.
  looking for simple couple cicles method.
  example. : <code>A[MxN] -&gt;&gt;&gt; B[MxN] (Sorted 1.....n)</code></p>
