Question

问候。我是编码的新手，所以对于某些人来说，我面临的这些问题可能很容易。我正在尝试制作一个简单的工具，以导出文件并读取文件中的价格数据。但是首先我需要能够导入\ Marketlogs中当前的文件。所有文件均为.txt。我得到它来解决一个集合名称，但我还没有找到导入未知名称的方法。这是一个文件名示例，它可能会拉“ Esoteria-Liquid Ozone-2019.05.04 015804”

我一直在跟随IAmTimCorey youtube视频，以获取有关如何读取文件的基本想法，但是他为视频使用了固定的文件名

请尝试以下代码：（获取目录，然后获取具有匹配文件模式的文件。然后一张一张地加载并像往常一样使用您的代码读取文件）

 var fileNamePattern = "*.txt";
 var dir = new DirectoryInfo(path);
 IEnumerable<FileSystemInfo> files = dir.GetFileSystemInfos(fileNamePattern);
 files
    .ToList()
    .ForEach(f=>        
    {
       //Load each file using File system Info:
       List<string> lines = File.ReadAllLines(f.FullName).ToList();
       //............
    });

这段代码让您陷入困境
