            string path = AppDomain.CurrentDomain.BaseDirectory+ @"\1";//这个目录要存在如没有自己添加,再加子目录文件等
            FileIndex(path, treeView1.Nodes);
            

        }

                string[] fileIndexPath = Directory.GetDirectories(fileIndex);
                foreach (string temp in fileIndexPath)
                {
                    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
            {

            }
          
        }
    }
}
