open csv one by one using loop

hi,

I have a program that can read CSV. How to make it loop to read CSV file and insert. Example one folder has 2 CSV file. The program will read 1.csv and insert. And then 2.csv and then insert. Please help me.

DirectoryInfo info = new DirectoryInfo(@"C:\folder\apoo");
FileInfo[] filess = info.GetFiles().OrderByDescending(p => p.LastWriteTime).ToArray();
string latestfile = "";
DateTime lastupdate = DateTime.MinValue;
var connString = "path";
foreach(FileInfo filess2 in filess)
{
if (filess2.LastWriteTime > lastupdate)
{
lastupdate = filess2.LastWriteTime;
latestfile = filess2.Name;
}
Console.WriteLine("File : " + latestfile);
Console.WriteLine("LWT : "+lastupdate);
}
