因为项目的需要，整理了一段C#操作sftp的方法。
依赖的第三方类库名称为：SharpSSH 1.1.1.13.
代码如下：
1: using System;
2: using System.Collections.Generic;
3: using System.Linq;
4: using System.Text;
5: using System.Collections.Specialized;
6: using System.Configuration;
7: using Tamir.SharpSsh;
8: using System.IO;
9: using Tamir.SharpSsh.jsch;
10:

39:
40: private static readonly string defRemotePath = "/";//默认操作是都是从根目录开始。
41: private ChannelSftp m_sftp;
