1.整理简化了下C#的ftp操作，方便使用
1.支持创建多级目录
2.批量删除
3.整个目录上传
4.整个目录删除
5.整个目录下载
2.调用方法展示，
var ftp = new FtpHelper("10.136.12.11", "qdx1213123", "123ddddf");//初始化ftp，创建ftp对象 ftp.DelAll("test");//删除ftptest目录及其目录下的所有文件 ftp.UploadAllFile("F:\test\wms.zip");//上传单个文件到指定目录 ftp.UploadAllFile("F:\test");//将本地test目录的所有文件上传 ftp.DownloadFile("test\wms.zip", "F:\test1");//下载单个目录 ftp.DownloadAllFile("test", "F:\test1");//批量下载整个目录 ftp.MakeDir("aaa\bbb\ccc\ddd");//创建多级目录
3.FtpHelper 代码。
1.异常方法委托,通过Lamda委托统一处理异常，方便改写。加了个委托方便控制异常输出
2.ftp的删除需要递归查找所有目录存入list，然后根据 level倒序排序，从最末级开始遍历删除
3.其他的整个目录操作都是同上
