title: Adding an element to an array
body: <p>I m reading data from a source as array. a[n]</p>
  
  <p>I need to add one more element to the array.</p>
  
  <p>Once i get the array, i create a new array with capacity n+1 and copy all the elements to the new array and put the new element as the last element of the array. </p>
  
  <p>I can do this.</p>
  
  <p>Is there a better way to do this? especially with Linq?</p>
