title: Add new line to String.Join?
body: <p>So I've been trying like crazy to add a new line to my <code>String.Join</code> printout but it seems it's not possible or Am i doing something wrong ? I've both tried using <code>"/n/r"</code> and <code>Enivrorment.NewLine</code> as well as a making a class too create a new line</p>
  
  <p>list box I'm trying to print out too</p>
  
  <pre><code>ListBox1.Items.Add("Calories to lose 0.5kg per week: " +
      string.Join(Environment.NewLine + "Calories to lose 1kg per week:",
          bc.LoseOrGainWeightCalories(bc.MaintainWightCalories(), true)));
  </code></pre>
  
  <p>calling on this class:</p>
  
  <pre><code>public string[] LoseOrGainWeightCalories(double weight, bool lose) {
      string[] array = new string[2];
      double LoseGainWeight = this.weight;
      if(lose==true) {
          array[0] = Convert.ToString(LoseGainWeight - 500);
          array[1] = Convert.ToString(LoseGainWeight - 1000);
      } else {
          array[0] = Convert.ToString(LoseGainWeight + 500);
          array[1] = Convert.ToString(LoseGainWeight + 1000);
      }
      return array;
  }
  </code></pre>
