title: create array of string builder instead of string
body: <p>I am creating an application in window application using c#. I have a string array,and its value will be updated in each timer tick event. later on ,i have to convert this array into object array. I know, if we are modifying string many times,it can be time consuming to create new string objects.so i want to use stringBuilder. </p>
  
  <p>let say, in timer tick event:</p>
  
  <pre><code>for (int i = 0; i &lt; 10; i++)
    {
       n[i] = i.ToString();
    }
  </code></pre>
  
  <p>where n is the string array and i want to use stringbuilder instead of array.
  is it possible? how do i do this? how do i convert stringBuilder type to object type?</p>
