File System TreeView

by

If you wanted to stick with the strings something like this would work…

TreeNode root = new TreeNode();
TreeNode node = root;
treeView1.Nodes.Add(root);

 foreach (string filePath in myList) // myList is your list of paths
 {
    node = root;
    foreach (string pathBits in filePath.Split("https://stackoverflow.com/"))
    {
      node = AddNode(node, pathBits);
    }
 }


private TreeNode AddNode(TreeNode node, string key)
{
    if (node.Nodes.ContainsKey(key))
    {
        return node.Nodes[key];
    }
    else
    {
        return node.Nodes.Add(key, key);
    }
}
