title: Cannot implicitly convert type to 'string' error
body: <p>I am currently working with displaying a list of items. I have created a method <code>GetNextItem</code> that returns <code>obj1</code>. When I am calling the method from the <code>buttonClick</code> I get this following error:</p>
  
  <pre class="lang-none prettyprint-override"><code>Cannot implicitly convert type 'TreeFarm.Form1.fruit_trees' to 'string'.
  </code></pre>
  
  <p>Not sure why is doing such thing.</p>
  
  <pre><code>public items_list GetNextItem()
  {
      items_list obj1 = this.current_item;
      if (obj1 != null)
      {
          current_item = current_item.next_item;
      }
      return obj1;
  }
  
  ListForItems mainlist = new ListForItems();
  private void ShowNextItem_Click(object sender, EventArgs e)
  {
  
      labelSpecificItem.Text = mainlist.GetNextItem();         
  }
  </code></pre>
