c# - SSH.Net库和通配符的使用

Question

我需要使用SSH.NET登录到SFTP并删除该文件夹中的所有文件，但是SSH.Net似乎不支持通配符。是真的吗有办法解决吗？这是我的代码。

using (SftpClient sftpClient = new SftpClient(server, port, username, password))
{
    foreach (var d in sftpClient.ConnectionInfo.Encryptions.Where(p => p.Key != "blowfish-cbc").ToList())
    {
        sftpClient.ConnectionInfo.Encryptions.Remove(d.Key);
    }

    sftpClient.Connect();
    sftpClient.DeleteFile("/outgoing/*.*");
    sftpClient.Disconnect();
}

Answer 1

我也不太喜欢使用该库的通配符。我刚刚创建了一个扩展方法(简单):

public static IEnumerable<SftpFile> ListDirectoryWC(this SftpClient client, string pattern, Func<SftpFile,bool> includeTest=null)
{
    string directoryName = (pattern[0] == '/' ? "" : "/") + pattern.Substring(0, pattern.LastIndexOf('/'));
    string regexPattern = pattern.Substring(pattern.LastIndexOf('/') + 1)
            .Replace(".", "\\.")
            .Replace("*", ".*")
            .Replace("?", ".");
    Regex reg = new Regex('^' + regexPattern + '$');

    var results = client.ListDirectory(String.IsNullOrEmpty(directoryName) ? "/" : directoryName)
        .Where(e => reg.IsMatch(e.Name) && (includeTest == null || includeTest(e)));
    return results;
}

public static void DeleteFileWC(this SftpClient client, string pattern, Func<SftpFile,bool> includeTest=null)
{
    foreach(var file in client.ListDirectoryWC(pattern, includeTest))
    {
        file.Delete();
    }
}
