Listing files and folders, TreeView usage problem.

There is problem with the Nodes.Add, What i need to create treeview as it should be

Here is the code, try run it if you dont see the problem.

private void Form1_Load(object sender, EventArgs e)
{

// Dirs
foreach (string dirs in Directory.GetDirectories(@"C:\"))
{
if (dirs != "C:\\System Volume Information")
{
TreeNode node = new TreeNode();
node.Text = dirs;
treeView1.Nodes.Add(node); // this works

// Subdirs
foreach (string test in Directory.GetDirectories(dirs))
{
TreeNode subdirs = new TreeNode();
subdirs.Text = test;
treeView1.Nodes.Add(subdirs); // here it is. Should be "sub node"

// Files
foreach (string files in Directory.GetFiles(node.Text))
{

TreeNode subNode = new TreeNode();
subNode.Text = files;
node.Nodes.Add(subNode);
}
}

Something like this Note the bold underlined text...

...
// Subdirs
foreach (string test in Directory.GetDirectories(dirs))
{
    TreeNode subdirs = new TreeNode();
    subdirs.Text = test;
    node.Nodes.Add(subdirs); // here it is. Should be "sub node"
    // Files
    foreach (string files in Directory.GetFiles(node.Text))
    {
        TreeNode subNode = new TreeNode();
        subNode.Text = files;
        subdirs.Nodes.Add(subNode);
    }
}
...

Use something like this:

protected void AppendDirectoriesToTreeNode( TreeNode node, string root )
{
DirectoryInfo rootDir = new DirectoryInfo( root );

foreach( DirectoryInfo subDir in rootDir.GetDirectories() )
{
TreeNode subdirNode = new TreeNode( subDir.Name );
AppendDirectoriesToTreeNode( subdirNode, subDir.FullName );

node.Nodes.Add( subdirNode );
}
}

Usages:

TreeNode node = new TreeNode( "c:\" );
AppendDirectoriesToTreeNode( node, "c:\" );

myTreeView.Nodes.Add( node );

Hope this helps
