                {
                    TreeNode node = treeNodes.Add(Path.GetFileName(temp));
                    FileIndex(temp, node.Nodes);//循环添加到没有子目录为止，注意有的像C盘里面不能防问的目录就会出问题，可以用try catch
                }
                string[] fileName = Directory.GetFiles(fileIndex);
                foreach (string temp in fileName)

                    treeNodes.Add(Path.GetFileName(temp));
                }
            }
            catch

            }
