SSH.Net 库和通配符的使用 [英] SSH.Net library and use of wild card

问题描述

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

I need to login to SFTP with SSH.NET and delete all files in the folder, but it seem like SSH.Net does not support wild card. Is it true? Is there way to fix it? Here is my code.

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();
}

推荐答案

我也不太喜欢使用这个库的通配符.我刚刚创建了一个扩展方法(简单):

I haven't had much luck with wildcards using this library, either. I just ended up creating an extension method (simplistic):

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();
    }
}
