Greeting. I am new to coding so these problems I am facing might be quite easy for some of you. I am trying to make a simple tool that takes an exported file and read the price data in the file. but first I need to be able to import the file that is currently in \Marketlogs. All of the files are .txt. I have gotten it to work off a set name but I have not found a way to import an unknown name. here is an example of a file name it might pull "Esoteria-Liquid Ozone-2019.05.04 015804"

I have been following along with IAmTimCorey youtube videos for the basic idea how to read the files but he is using a fixed file name for his videos

Please try following code: (get the directory and then get the files having matching file pattern. Then load one by one and use your code as usual to read files)

 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();
       //............
    });
