使用路径枚举填充树视图

Question

我正在尝试用列表项填充树视图。项目包含名称和路径：

代码如下：

private void CreateTree(TreeNodeCollection nodeList, string path, string name)
    {
        TreeNode node = null;
        string f = string.Empty;

        int p = path.IndexOf('/');

        if (p == -1)
        {
            f = path;
            path = "";
        }
        else
        {
            f = path.Substring(0, p);
            path = path.Substring(p + 1, path.Length - (p + 1));
        }

        node = null;

        foreach (TreeNode item in nodeList)
        {
            if (item.Text == f)
            {
                node = item;                   
            }
        }

        if (node == null)
        {
            node = new TreeNode(f);
            nodeList.Add(node);
        }

        if (path != "")
        {
            CreateTree(node.Nodes, path, name);
        }
    }

填充列表并创建树：

List<Item> list = new List<Item>();

list.Add(new Item { Name = "Parent", Path = "1" });
list.Add(new Item { Name = "daughter", Path = "1/2" });
list.Add(new Item { Name = "son", Path = "1/3" });
list.Add(new Item { Name = "daughter", Path = "1/2/4" });
list.Add(new Item { Name = "daughter", Path = "1/2/5" });
list.Add(new Item { Name = "son", Path = "1/3/6" });
list.Add(new Item { Name = "son", Path = "1/3/7" });
list.Add(new Item { Name = "son", Path = "1/2/5/8" });
list.Add(new Item { Name = "daughter", Path = "1/2/5/9" });
list.Add(new Item { Name = "daughter", Path = "1/3/6/10" });
list.Add(new Item { Name = "son", Path = "1/3/6/11" });
list.Add(new Item { Name = "daughter", Path = "1/3/7/12" });
list.Add(new Item { Name = "daughter", Path = "1/3/7/13" });
list.Add(new Item { Name = "daughter", Path = "1/3/7/14" });


foreach (Item line in list)
{
    CreateTree(treeView1.Nodes, line.Path, line.Name);
}

class Item
{
    public string Name { get; set; }
    public string Path { get; set; }
}

这工作正常，但我想显示名称而不是路径的最后编号。怎么做？

您的函数一切正常，但几乎不需要修改。我已经替换了：

foreach (TreeNode item in nodeList)
        {
            if (item.Text == f)
            {
                node = item;                   
            }
        }

到

foreach (TreeNode item in nodeList)
            {
                if (item.Tag.ToString() == f)
                {
                    node = item;
                }
            }

和

if (node == null)
        {
            node = new TreeNode(f);
            nodeList.Add(node);
        }

到

if (node == null)
            {                
                node = new TreeNode(name);
                node.Tag = f;
                nodeList.Add(node);
            }

希望对您有所帮助:)
