sftp上传文件(Renci.SshNet)和代理上传
引用Renci.SshNet这个
封装的sftp类

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[1]; methods[0] = new PasswordAuthenticationMethod(_sftp_set.username, _sftp_set.password); ConnectionInfo connectionInfo = new ConnectionInfo(_sftp_set.ip, _sftp_set.port, _sftp_set.username, (ProxyTypes)3, "代理地址", 1080, "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");
