直接账号密码

sftpHelp = new SFTPHelper(model.ip, model.port, model.username, model.password);
if (sftpHelp.Connect())
{
   //代码
}

代理上传

var methods = new AuthenticationMethod[];
methods[] = new PasswordAuthenticationMethod(_sftp_set.username, _sftp_set.password);
ConnectionInfo connectionInfo = new ConnectionInfo(_sftp_set.ip, _sftp_set.port, _sftp_set.username, (ProxyTypes), "代理地址", , "用户", "密码", methods);
sftpHelp = new SFTPHelper(connectionInfo);
if (sftpHelp.Connect())
{
    //代码
}

上传

sftpHelp.Put(@"C:\Users\admin\Desktop\3.png", @"/in/image/work/test.png");//上传图片

获取文件目录下的文件

ArrayList arrl = sftpHelp.GetFileList(@"/in/image/work/", "png");//文件名数组

移动文件

sftpHelp.Move(@"/in/image/work/3.png", @"/in/buid/3.png");

删除文件

sftpHelp.Delete(@"/in/image/work/3.png");
