求助!关于WPF中ListView绑—ataTable问题

C# code

TreeViewItem selectedItem = (TreeViewItem)folderTreeView.SelectedItem;            string selectedPath = (string)selectedItem.Tag;            string[] files = Directory.GetFiles(selectedPath);            this.fileListView.Items.Clear();            DataTable dataTable = new DataTable();            dataTable.Columns.Add("Name",Type.GetType("System.String"));            dataTable.Columns.Add("LastModifiedTime",Type.GetType("System.String"));            dataTable.Columns.Add("Size",Type.GetType("System.String"));            foreach(string file in files)            {                FileInfo fileInfo = new FileInfo(file);                string[] items= new string[] { fileInfo.Name, fileInfo.LastWriteTime.ToString(), fileInfo.Length.ToString() };                dataTable.Rows.Add(items[0], items[1], items[2]);            }            this.fileListView.DataContext = dataTable;

我写完后调试无法显示出内容，listView中还是没有数据显示，求解决！！！

[解决办法]
this.fileListView.DataContext = dataTable;

先把基础弄明白再动手,WPF绑定是怎么玩的你知道吗?
