title: Winform Treeview find node by tag
body: <p>I have a treeview where the display member could possibly have duplicates, and the tag would not. Example:</p>
  
  <pre><code>TreeNode node = new TreeNode(itemName);
  node.Tag = itemID; //unique ID for the item
  treeView1.Nodes.Add(node);
  </code></pre>
  
  <p>So, when searching, I know I can search by the itemName by using</p>
  
  <pre><code>treeView1.Nodes.Find(itemName, true);
  </code></pre>
  
  <p>But how could I go about searching via the tag? There's no definition for treeView1.Nodes.Where, so no linq for me :(</p>
  
  <p>Any suggestions on how to search by the tag? :) Thank you!</p>
