通用类库-FTPClient帮助类，实现文件上传，目录操作，下载等动作
直接上代码，这个也是我在网上找到的，自己测试修改后才公布出来的，大家可以放心使用，好的东西要分享，随时记录下来，好记性不如烂笔头，这个非常适合工作的。

调用代码如下
1 string userName = "xxx"; 2 string password = "xxx"; 3 DotNet.Utilities.FTPClient ftp = new DotNet.Utilities.FTPClient("127.0.0.1", ".", userName, password, 1021); 4 ftp.Put(@"C:\Users\yanghenglian\Desktop\单号图片\", "*");
效果图片
