wpf中一个数据处理的问题

Question

D:\123\1\2k

D:\123\2\en-us

D:\345\en\vista64

D:\345\_en\xp

D:\678\zh\xp64

上面是数据。 怎么样能把这些数据形成一个树形

即 d:

123

               1

2

345

678 (其余.....)

前台：    <TreeView Name="treeview"></TreeView>

Answer 1

这是我现在的想法

按照这条数据的路径，按顺序转成tree，但是 不是我心里要的，现在不知道怎么改，麻烦各位了。 

string tempchar = @"D:\123\1\2k*D:\123\2\en-us*D:\345\en\vista64*D:\345\_en\xp*D:\678\zh\xp64";
            string[] tempchars = tempchar.Split(new string[]{"*"},StringSplitOptions.RemoveEmptyEntries);
            System.Windows.Controls.TreeViewItem treestr;
            foreach (string str in tempchars)
            {
                string[] treeitemStr = str.Split(new string[] { "\\" }, StringSplitOptions.RemoveEmptyEntries);

                treestr = new System.Windows.Controls.TreeViewItem();
                treestr.IsExpanded = true;
                AddTreeItem(treestr, treeitemStr,0);
                treeview.Items.Add(treestr);
            }

/// <summary>
        /// 按照一个路径生成树形
        /// </summary>
        /// <param name="treestr"></param>
        /// <param name="pChild"></param>
        /// <param name="p"></param>
        private void AddTreeItem(TreeViewItem treestr, string[] pChild, int p)
        {
            System.Windows.Controls.TreeViewItem childTreeItem = new System.Windows.Controls.TreeViewItem();
            childTreeItem.Header = pChild[p];
            childTreeItem.IsExpanded = true;
            StringBuilder sbuild = new StringBuilder();
            for (int i = 0; i <= p; i++)
            {
                sbuild.Append(pChild[i]);
                sbuild.Append("\\");
            }
            childTreeItem.Tag = sbuild.ToString();
            string name = "p" + p.ToString();
            childTreeItem.Name = name;
            treestr.Items.Add(childTreeItem);
            p++;
            if (pChild.Length <= p) return;
            AddTreeItem(childTreeItem, pChild, p);
        }

 

Answer 2

没按着你的写。但是这个结构你理解一下。我是用绑定

 

 public partial class topics
    {
        private ObservableCollection<topics> childTopics = new ObservableCollection<topics>();

        public ObservableCollection<topics> ChildTopics
        {
            get { return childTopics; }
            set { childTopics = value; }
        }
        public topics(string Title, int Rating)
        {
            this.Title = Title;
            this.Rating = Rating;
        }
    }
    //public class Topic
    //{
    //    public string Title { get; set; }
    //    public int Rating { get; set; }
    //    private ObservableCollection<Topic> childTopicsValue = new ObservableCollection<Topic>();
    //    public ObservableCollection<Topic> ChildTopics
    //    {
    //        get
    //        {
    //            return childTopicsValue;
    //        }
    //        set
    //        {
    //            childTopicsValue = value;
    //        }
    //    }
    //    public Topic() { }
    //    public Topic(string title, int rating)
    //    {
    //        Title = title;
    //        Rating = rating;
    //    }
    //}

 

 

 

//Topics.Add(new Topic("Using Controls and Dialog Boxes", -1));
            //Topics.Add(new Topic("Getting Started with Controls", 1));
            //Topic DataGridTopic = new Topic("DataGrid", 4);
            //DataGridTopic.ChildTopics.Add(
            //    new Topic("Default Keyboard and Mouse Behavior in the DataGrid Control", -1));
            //DataGridTopic.ChildTopics.Add(
            //    new Topic("How to: Add a DataGrid Control to a Page", -1));
            //DataGridTopic.ChildTopics.Add(
            //    new Topic("How to: Display and Configure Row Details in the DataGrid Control", 1));
            //Topics.Add(DataGridTopic);
            //this.treeView1.DataContext = Topics;
            this.treeView1.DataContext = dc.topics;
