zip a group of files by their file name

Question

I have a list of logfiles which have their creation-date in their filename. I'm trying to zip the files together by date. Obviously I'm doing something wrong. How can I achieve this? This program is going to be a scheduled executable that zip log files every day, hence the currentDate variable. It could be 1 or several logfiles so the program should not depend on a number of files to zip.

These are the names of the log files:
Log_2021-06-17_1.txt,
Log_2021-06-17_2.txt,
Log_2021-06-17_3.txt

string currentDate = DateTime.Today.ToString("yyyy-MM-dd");
            var logDir = new DirectoryInfo(@"C:\Users\user\Desktop\LogFilesTEST\In\");
            foreach (FileInfo logFile in logDir.GetFiles())
            {
                if (logFile.Name.Contains(currentDate))
                {
                    string startPath = @"C:\Users\user\Desktop\LogFilesTEST\In\" + logFile.Name;
                    string zipPath = @"C:\Users\user\Desktop\LogFilesTEST\Archive\" + logFile.Name + ".zip";

                    ZipFile.CreateFromDirectory(startPath, zipPath);
                }              
            }

Edit: if someone has the same problem here is what i did in my Console application:

Program Class

 class Program
    {
        static void Main(string[] args)
        {
            string currentDate = DateTime.Today.ToString("yyyy-MM-dd");
            var logDir = new DirectoryInfo(@"C:\Users\user\Desktop\LogFilesTEST\In\");
            List<FileInfo> LogFileList = new List<FileInfo>();
            foreach (FileInfo logFile in logDir.GetFiles())
            {
                if (logFile.Name.Contains(currentDate))
                {
                    LogFileList.Add(logFile);
                }              
            }

            Zipper.CreateZipFile(LogFileList, @"C:\Users\user\Desktop\LogFilesTEST\Archive\Logs_" + currentDate + ".zip");

            foreach(var logfile in LogFileList)
            {
                logfile.Delete();
            }

        }
    }

Zipper Class:

class Zipper
    {       
        public static void CreateZipFile(List<FileInfo> files, string archiveName)
        {
            using (var stream = File.OpenWrite(archiveName))
            using (ZipArchive archive = new ZipArchive(stream, System.IO.Compression.ZipArchiveMode.Create))
            {
                foreach (var item in files)
                {
                    archive.CreateEntryFromFile(item.FullName, item.Name, CompressionLevel.Optimal);
                }
            }
        }
    }
