Question

Im working with file systems and I have a List<> of file objects that have the file path as a property. Basically I need to create a treeview in .NET but im struggling to think of the best way to go about doing this as I need to create a tree structure from a list like:

C:/WINDOWS/Temp/ErrorLog.txt C:/Program Files/FileZilla/GPL.html C:/Documents and Settings/Administrator/ntuser.dat.LOG 

etc….

The list is not structured at all and I cant make any changes to the current object structure.

I’m working in C#.

Many thanks for all who contribute

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('/'))     {       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);     } }
