title: TreeNodeCollection reference problem
body: <p>First off we have the almighty code!</p>
  
  <pre><code>List nodes = new List();
  TreeNode Temp = new TreeNode();
  
  TreeNodeCollection nodeList = treeViewTab4DirectoryTree.Nodes;
  
  while (nodeList.Count != 0)
  {
      Temp = nodeList[0];
  
      while (Temp.FirstNode != null)
      {
          Temp = Temp.FirstNode;
      }
  
      if (!nodes.Contains(Temp.FullPath))
      {
          nodes.Add(Temp.Text);
      }
  
      nodeList.Remove(Temp);
  }</code></pre>
  
  <p>Now the problem:  I have written the code above with the intent of creating a List containing the text from all the nodes in the tree. That works perfectly.  The problem I am having is when I remove the nodes from my variable they are also being removed from the actual list.  The question would be how can I make a copy of the list of nodes so I can play with them without messing with the ACTUAL list.  How do I make a copy of it without just making a reference to it?  Any help will be greatly appreciated!</p>
