FTP文件清理器的清理实现

Question

我正在重构测试项目中使用的一些实用程序代码模块，并希望应用我对干净的OOP设计模式和坚实原则的知识，使这些模块更有用，更易于使用。

我有一个名为IFtpFileCleaner的接口：

/// 
/// Responsible for deleting a single file located in a remote server
/// 
public interface IFtpFileCleaner
{
    /// 
    /// Deletes a remote file
    /// 
    /// 
    /// The full remote path.
    /// 
    void Clean(string remotePath);
}

我有一个名为RemoteFileCleaner的抽象类，它实现了IFtpFileCleaner：

/// 
/// The file cleaner base class provides common code for all the implementations to reduce code duplication
/// 
public abstract class RemoteFileCleaner : IFtpFileCleaner
{
    /// 
    /// The FTP _client.
    /// 
    private readonly IFtpSecureClient _client;

    /// 
    /// Initializes a new instance of the  class.
    /// 
    /// 
    /// The FTP client.
    /// 
    protected RemoteFileCleaner(IFtpSecureClient client)
    {
        _client = client;
    }

    /// 
    /// Deletes a single file located on a remote server
    /// 
    /// 
    /// The full path of the remote file.
    /// 
    public void Clean(string remotePath)
    {
        try
        {
            _client.Init();
            _client.DeleteFile(remotePath);
        }
        catch (Exception e)
        {
            Console.WriteLine($"Failed to clean file {remotePath}.{Environment.NewLine}{e}");
            throw;
        }
        finally
        {
            _client.Disconnect();
        }
        Console.WriteLine($"Remote File {remotePath} was deleted.");
    }
}

现在，我可以有我的文件清理器的具体实现。比如SFTPFileCleaner，FTPFileCleaner和FTPSFileCleaner。它们看起来都很相似。例如，SFTPFileCleaner如下所示：

/// 
/// The SFTP implementation of .
/// 
public class SFTPFileCleaner : RemoteFileCleaner
{
    /// 
    /// Initializes a new instance of the  class.
    /// 
    public SFTPFileCleaner()
        : base(new FtpSecureClientTestFactory().CreateSFTPClient())
    {
    }
}

如您所见，我在具体实现中执行"Bastard注入“，因为我希望在测试方法中很容易地实例化这些清洁剂。下面是一个示例：

[TearDown]
public void Cleanup()
{
    _ftpCleaner = new SFTPFileCleaner();
    _ftpCleaner.Clean(_expectedRemotePath);
}

1. 你们觉得这个设计怎么样？它干净易用吗？
2. 还能再改进吗？
3. 这个设计模式有名字吗？在我看来，似乎是正面模式(Bastard注入)和策略模式的混合。我说的对吗？

让IRemoteFileCleaner作为基类，并将FTPFileCleaner (从IRemoteFileCleaner继承来作为所有其他类继承的类)难道不是更有意义的吗？
