SharpSvn: Getting repository structure and individual files

I want to make a repository browser for my SVN folder so that the user can choose one folder and it will be return to a text box.

This is my actual code :

    private void sourceTrunkBrowseButton_Click(object sender, EventArgs e)
     {
         using (SvnClient svnClient = new SvnClient())
         {
             Collection<SvnListEventArgs> contents;
             Collection<SvnListEventArgs> contents2;
             List<TreeItem> files = new List<TreeItem>();
             if (svnClient.GetList(new Uri("https://sourcecode/svn/XXXXXX"), out contents))
             {
                 foreach (SvnListEventArgs item in contents)
                 {
                     if (item.Path != "")
                     {
                         files.Add(new TreeItem(item.Path, 0));

                         if (svnClient.GetList(new Uri("https://sourcecode/svn/XXXXX" + item.Path), out contents2) && item.Path != "")
                         {
                             foreach (SvnListEventArgs item2 in contents2)
                             {
                                 if (item2.Path != "")
                                 {
                                     files.Add(new TreeItem(item2.Path, 1));
                                 }
                             }
                         }
                     }
                 }
             }
             svnBrowser_.FillMyTreeView(files);
             svnBrowser_.Show();
         }
     }

And

  public void FillMyTreeView(List<AutoTrunk.TreeItem> files) 
 {

       // Suppress repainting the TreeView until all the objects have been created.
        svnTreeView.BeginUpdate();

        svnTreeView.Nodes.Clear();
        List<TreeNode> roots = new List<TreeNode>();
         roots.Add(svnTreeView.Nodes.Add("Items"));
         foreach (AutoTrunk.TreeItem item in files)
     {
         if (item.Level == roots.Count) roots.Add(roots[roots.Count - 1].LastNode);
         roots[item.Level].Nodes.Add(item.BrowsePath);
     }

        // Begin repainting the TreeView.
        svnTreeView.EndUpdate();
 }

But my tree look like this :

+---Name1
|   |
|   +------Name2
|   |
|   +------Name3
|   |
|   +------Name5
|   |
|   +------Name6
|
+---Name4

but Name 5 and Name 6 should be under Name 4

Sorry for the long post and thanks!

Answer 1

if(item.Level == roots.Count) is your problem I'm thinking... Are you sure the items have the correct level? For example, if Name1 and Name4 are roots, then what happens after you've encountered your second root? Does this give the intended result:

TreeNode root = svnTreeView.Nodes.Add("Items");
TreeNode workingNode = root;
foreach (AutoTrunk.TreeItem item in files)
{
    if (item.Level == 0) 
        workingNode = root.Nodes.Add(item.BrowsePath);
    else
        workingNode.Nodes.Add(item.BrowsePath);
}

Just a thought.
