title: Convert String To Nullable Integer List
body: <p>I'm wanting to parse a string into a nullable int list in C#</p>
  
  <p>I'm able to convert it to int list bit not a nullable one</p>
  
  <pre><code>string data = "1,2";
  List&lt;int&gt; TagIds = data.Split(',').Select(int.Parse).ToList();
  </code></pre>
  
  <p>say when data will be empty i want to handle that part!</p>
  
  <p>Thanks</p>
