title: string class disposable method
body: <pre><code>private void test()
  {
      string tst = null;
      try
      {
          tst = "abc";     
      }
      catch (Exception)
      {
          throw;
      }
      finally
      {
          tst = null;           
      }
  }
  </code></pre>
  
  <p>My query is - Is it meaningful to type <code>tst = null;</code> in the finally block as the string class doesn't have the disposable method ?</p>
