如何使用 C# 和 WinSCP 模式获取远程目录的文件

问题描述

我正在尝试从具有 FTP/SFTP 连接的远程服务器获取特定文件，我遇到的问题是，我正在尝试获取具有特定模式的远程目录中的文件数.我正在使用面具，但对我不起作用，它会引发异常:这就是我所拥有的

I'm trying to get an specific files from a remote server with FTP/SFTP connection, the issue that I'm having is, I'm trying to get the count of files in the remote directory with an specific pattern. I'm using a mask but is not working for me, it throwing an exception: this is what I have

DataFile.sRemoteDirectory = "/user/ftpuser/test/";
receivepattern = "Del*";
filesCount =
    session.ListDirectory(
        session.EscapeFileMask(DataFile.sRemoteDirectory + receivepattern))
    .Files.Where(x => !x.IsDirectory).Count();

推荐答案

Session.ListDirectory 方法 不接受通配符，只接受路径.

The Session.ListDirectory method does not accept a wildcard, only a path.

由于 WinSCP .NET 程序集 5.9，您可以使用 Session.EnumerateRemoteFiles方法改为:

filesCount =
    session.EnumerateRemoteFiles(
        DataFile.sRemoteDirectory, receivepattern, EnumerationOptions.None).Count();

Regex r = new Regex("^Del.*");

filesCount = session.ListDirectory(DataFile.sRemoteDirectory).Files
    .Where(x => !x.IsDirectory)
    .Where(x => r.Match(x.Name))
    .Count()
