.Net读取共享文件夹的通用方法

定义类：

 1 public class ShareFolderHelper : IDisposable

 5                     var dicInfo = new DirectoryInfo(Path);//选择的目录信息    
 6 
 7                     //得到文件夹列表
 8                     DirectoryInfo[] folderList = dicInfo.GetDirectories("*.*", SearchOption.TopDirectoryOnly);
 9                     //得到文件列表
10                     FileInfo[] fileList = dicInfo.GetFiles("*.*", SearchOption.TopDirectoryOnly);//获取所有目录包含子目录下的文件
11                     
12                     if (folderList.Length > 0 || fileList.Length > 0)
13                     {
14                         //Step1: 得到根Folder(包含创建)
15                         SF_FOLDER rootArasFolder = GetArasRootFolder(connector);
16 
17                         //Step2: 同步文件
