Binding Directory to treeview in C# with visual studios

Does anyone know how to bind a directory to a treeview in C# or know of a开发者_如何学JAVA simple tutorial to follow along with? Thanks

Something like this:

    public void BindDirectoryToTreeView(string directoryPathToBind)
    {
        TreeNode rootNode = new TreeNode();
        treeView1.Nodes.Add(rootNode);
        RecurseFolders(directoryPathToBind, rootNode);
    }

    public void RecurseFolders(string path, TreeNode node)
    {
        var dir = new DirectoryInfo(path);
        node.Text = dir.Name;

        try
        {
            foreach (var subdir in dir.GetDirectories())
            {
                var childnode = new TreeNode();
                node.Nodes.Add(childnode);

                RecurseFolders(subdir.FullName, childnode);
            }
        }
        catch (UnauthorizedAccessException ex)
        {
            // TODO:  write some handler to log and/or deal with 
            // unauthorized exception cases
        }

        foreach (var fi in dir.GetFiles().OrderBy(c=>c.Name))
        {
            var fileNode = new TreeNode(fi.Name);
            node.Nodes.Add(fileNode);
        }
    }

You would invoke the code by calling BindDirectoryToTreeView("c:\"); for instance. Note that you should have a treeview named treeView1 on the form that has this code.

You can use simple recursion .Not sure what exactly you want to display in TreeView but the following approach can work

public static void LoadDir(TreeNode t,DirectoryInfo d) {

TreeNode tn= new TreeNode(d.name);

t.ChildNodes.Add(tn);

foreach(DirectoryInfo dn in d.GetDirectories())

LoadDir(tn,dn); }

You can Invoke it as

TreeNode tn=new TreeNode("Root");

TreeView1.Nodes.Add(tn);

LoadDir(tn,new DirectoryInfo(@"C:\Oracle");
