Adapter for an object that implenets ITreeNode interface to TreeNode for TreeView

suppose We have the interface :

public interface ITreeNode
    {
        string Text { get; set; }
        IEnumerable<ITreeNode> Nodes { get; set; }
    }

Suppose that we have the first node of a tree where every object implents that interface.

What is an easy way to display that tree ( a tree of ITreeNode ) in TreeView?

In other word, how do I adapt the entire tree of ITreeNode to System.Windows.Forms.TreeNode for System.Windows.Forms.TreeView ?

Please note : The above interface is just for getting an idea, if an alternative w开发者_StackOverflow中文版ay for adpating trees nodes of some type to TreeNodes for TreeView exist please advise.

The Windows Forms TreeView will only ever operate on the type TreeNode, so you will need some kind of conversion if you want to use instances of ITreeNode with the control. I suggest an extension method, such as the one below:

public static class TreeViewExtensions {

    public static void Add(this TreeNodeCollection nodes, ITreeNode node) {
        TreeNode treeNode = new TreeNode(node.Text);
        foreach (ITreeNode child in node.Nodes) treeNode.Nodes.Add(child);
        nodes.Add(treeNode);
    }
}

Then you can just add your node (and all children, and all children's children, etc) to a TreeView control with little fuss:

myTreeView.Nodes.Add(myInstanceOfITreeNode);

With that said, there isn't a huge advantage in working with objects of a foreign interface and then converting to a TreeNode representation - you might as well just work directly with the actual node class.
