遍历路径下的所有文件

1、先挂最顶级节点

 TreeListNode pNode = tlFileDisplay.AppendNode(new object[] { beOpen.Text }, -1);
 GetAllDirectory(beOpen.Text, tlFileDisplay, pNode);

函数：

         /// <summary>
        /// 遍历文件夹
        /// </summary>
        /// <param name="sPath">当前路径</param>
        /// <param name="tlList">树结构</param>
        /// <param name="pNodeParent">父节点</param>
        private void GetAllDirectory(string sPath,TreeList tlList,TreeListNode pNodeParent)
        {
            string[] sDirectory = Directory.GetDirectories(sPath);
            foreach (string sDirPath in sDirectory)
            {
                TreeListNode pNode = tlFileDisplay.AppendNode(new object[] { sDirPath }, pNodeParent);
                GetAllFiles(sDirPath, tlList, pNode);
                GetAllDirectory(sDirPath, tlList, pNode);
            }
        }

        /// <summary>
        /// 遍历文件
        /// </summary>
        /// <param name="sPath">路径</param>
        /// <param name="TreeList">树结构</param>
        /// <param name="ParentNode">父节点</param>
        private void GetAllFiles(string sPath, TreeList TreeList, TreeListNode ParentNode)
        {
            string[] sFiles = Directory.GetFiles(sPath);
            foreach (string sFileName in sFiles)
            {
                TreeList.AppendNode(new object[] { sFileName }, ParentNode);
            }
        }
