From A Path I Ahve To Read The Three Difrennt Folder And To Load That Folder To A Tree Control In C#

string folderLocation1 = @"D:\OLD Projects\BEData\BEData\Scripts";
           string folderLocation2 = @"D:\OLD Projects\BEData\BEData\Styles\css";
           string folderLocation3 = @"D:\OLD Projects\BEData\BEData\Images";

           treeView1.Nodes.Add("scripts");
           TreeNode[] tn1 = new DirectoryInfo(folderLocation1).GetFiles().Select(k => new TreeNode() { Text = (k.Name) }).ToArray();
           treeView1.Nodes[0].Nodes.AddRange(tn1);

           TreeNode[] tn2 = new DirectoryInfo(folderLocation2).GetFiles().Select(k => new TreeNode() { Text = (k.Name) }).ToArray();
           treeView1.Nodes.Add("csss");
           treeView1.Nodes[1].Nodes.AddRange(tn2);

           TreeNode[] tn3 = new DirectoryInfo(folderLocation3).GetFiles().Select(k => new TreeNode() { Text = (k.Name) }).ToArray();
           treeView1.Nodes.Add("images");
           treeView1.Nodes[2].Nodes.AddRange(tn3);
