Title Body

In my C# WinForms program I have a treeview that only contains parent nodes (so, no childs) it is like a listbox but I needed it because of haveing differet properties of nodes like Name, Tag and Text. No I want to be able to save the content of this treeview into a file (Basically a text file which I call it *.MVIA). The question is what is the best way to save all three properties of nodes in a file so it can loaded again later properly? At the moment I came with this idea : private void menuFileSave_Click(object sender, EventArgs e) { StringBuilder sb = new StringBuilder(); foreach(TreeNode node in treeViewFiles.Nodes) { sb.AppendLine(node.Name); } SaveFileDialog saveList = new SaveFileDialog(); saveList.DefaultExt = "*.mvia"; saveList.Filter = "MVIA Files|*.mvia"; if (saveList.ShowDialog() == DialogResult.OK) { File.WriteAllText(saveList.FileName, sb.ToString()); } } As you can see, each Name property of each node will be saved in a line. Now I need to add its Text and Tag property also, but later I have trouble reading it back (Honestly I don't know how to). Would you give me some ideas what is a best way to save all three property of each node and be able to load it easily later? Thanks.
