c# - 当我使用 SftpClient.UploadFile()（在 SSH.NET 库上）时，如何获得响应状态和描述？

Question

using (SftpClient client = new SftpClient(ftpUrl, port, username, password))
{
    KeyValuePair<string, CipherInfo> temp = client.ConnectionInfo.Encryptions.FirstOrDefault(e => e.Key == sftpEncryption);
    if (temp.Key == sftpEncryption)
    {
        client.ConnectionInfo.Encryptions.Clear();
        client.ConnectionInfo.Encryptions.Add(temp);
    }

    client.Connect();
    Stream stream = null; // some data to upload

    // The upload works fine but how can I see the response code (numeric code) and the response message from the server.
    client.UploadFile(stream, "my_data.bin"); 
} 

UploadFile 方法工作得很好。但是，我希望在上传完成后从 FTP 服务器获取状态代码（数字代码）和响应消息。UploadFile 方法返回 void，回调给了我一个 ulong，我认为这是上传文件的大小。我有没有机会使用这个库从服务器获取响应信息？
