title: How to append character in long integer?
body: <p>I want to append a character to a long integer, using the below code:</p>
  
  <pre><code>if (strArrIds[1].Contains("CO"))
  {
      long rdb2 = Convert.ToInt64(strArrIds[1].Substring(strArrIds[1].Length - 1));
      assessmentEntity.RatingType = rdb2;
  }
  </code></pre>
  
  <p>If <code>rdb2 = 5</code>, I want to append a <code>L</code> to this value, like <code>rdb2 = 5L</code>.</p>
  
  <p>Any ideas? Thanks in advance.</p>
