title: List<T> or LinkedList<T>
body: <p>I need a data structure that holds a list of elements of the same type. Needed features are</p>
  
  <ul>
  <li>Add</li>
  <li>GetEnumerator</li>
  <li>(may be) Clear</li>
  </ul>
  
  <p>An indexed access, sorting, searching, removing of elements are <em>not required</em>. What is the best collection class for it? The following aspects should be taken in consideration: performance, memory usage, behavior of the garbage collector. </p>
  
  <p>My current candidates are <code>List&lt;T&gt;</code> and <code>LinkedList&lt;T&gt;</code></p>
