title: passing a List of Lists as a parameter
body: <p>I have a List of Lists of strings and I want to pass it to another method.</p>
  
  <p>I am a little confused about Lists and I don't know how to handle them.</p>
  
  <pre><code>public Form(string[] header, List&lt;&gt; data)
  </code></pre>
  
  <p>Is List a data type (or Object)? because the error VS2010 says that its expecting a type.</p>
