title: How to return contents of a List<char>
body: <pre><code> public List&lt;char&gt; Columns(String input)
      {
          char[] temp = input.ToCharArray();
          List&lt;char&gt; columns = new List&lt;char&gt;(input.Length);
          for (int i = 0; i &lt; input.Length; i++)
          {
              if (other.Contains(temp[i]))
              {
                  columns.Add((char)(i+1));
              }
          }
          return columns;
      }
  </code></pre>
  
  <p>My goal here was to have this method return a List. However, when I went to output the contents in another method I got 'System.Collections.Generic.List[char]</p>
  
  <pre><code>Console.WriteLine(ex.Columns(line));
  </code></pre>
  
  <p>That was my attempt to output it.</p>
