#region 构造

public SFTPHelper(string ip, string user, string pwd, string port = "22")
{
sftp = new SftpClient(ip, Int32.Parse(port), user, pwd);
Connect();
}
~SFTPHelper()
{
Disconnect();
}
#endregion
#region 连接SFTP

public bool Connect()
{
try

}
catch (Exception ex)
{
throw new Exception(string.Format("连接SFTP失败，原因：{0}", ex.Message));
}
}
#endregion
#region 断开SFTP

}
}
#endregion
#region SFTP上传文件

public bool Put(string localPath, string remotePath)

调用：
1、上传文件：
private void UploadLabel(string remotePath, string localFile, string remoteFileName)
{
SFTPHelper sftp = new SFTPHelper(labelServerInfo.LabelServerIp, labelServerInfo.LabelServerUser, labelServerInfo.LabelServerPassWord,labelServerInfo.LabelServerPort);
if (!sftp.CheckDirectoryExist(sftp.RemotePath, remotePath))
{
string remotepath = "/" + remotePath + "/";
if (!sftp.MakeDirectory(remotepath))
{
AppendTextColorful("Create Remote Path Error,Path already exists", Color.Orange, true);
}
}
else
{
string remotepath = "/" + remotePath + "/";
sftp.RemotePath = remotepath;
}
sftp.RemotePath = "/" + remotePath + "/";
if (sftp.CheckFileExist(remoteFileName))
{
if (DialogResult.Yes != MessageBox.Show("Remote File is Exist, Override ?", "Message:", MessageBoxButtons.YesNo, MessageBoxIcon.Question)) { return; }
if (!sftp.Delete(sftp.RemotePath + remoteFileName))
{
AppendTextColorful("Delete Remote File Error", Color.Red, true);
}
if (!sftp.Put(localFile, sftp.RemotePath + remoteFileName))
{
AppendTextColorful("Upload Remote File Error", Color.Red, true);
}
else
{
AppendTextColorful("Upload Remote File OK", Color.Blue, true);
}
}
else
{
if (!sftp.Put(localFile, sftp.RemotePath + remoteFileName))
{
AppendTextColorful("Upload Remote File Error", Color.Red, true);
}
else
{
AppendTextColorful("Upload Remote File OK", Color.Blue, true);
}
}
}
2、下载文件：
private void DownLoadLabel(string remotePath,string remoteFile,string localFileName)
{
try
{
SFTPHelper sftp = new SFTPHelper(labelServerInfo.LabelServerIp, labelServerInfo.LabelServerUser, labelServerInfo.LabelServerPassWord, labelServerInfo.LabelServerPort);
sftp.RemotePath = "/" + remotePath + "/";
if (!sftp.CheckFileExist(remoteFile))
{
AppendTextColorful("Remote File Not Exist", Color.Red, true);
return;
}
if (!sftp.Get(sftp.RemotePath+remoteFile, localFileName))
{
AppendTextColorful("Download Remote File Error", Color.Red, true);
}
else
{
AppendTextColorful("Download Remote File OK", Color.Blue, true);
}
}
catch (Exception ex) { AppendTextColorful(ex.Message, Color.Red, true); }
}
