Answer 1

If there are sub folders you want

string[] oFiles = Directory.GetFiles(sPath, "*", SearchOption.AllDirectories);

otherwise you want

string[] oFiles = Directory.GetFiles(sPath);

or if you want to filter you want

string[] oFiles = Directory.GetFiles(sPath, "*");

To filter by .txt extension replace * with *.txt as the second argument.

Answer 2

This is some code to read the files in a directory:

DirectoryInfo di = new DirectoryInfo("c:/root1");
FileInfo[] rgFiles = di.GetFiles("*.*");
foreach(FileInfo fi in rgFiles)
{
   Response.Write("<br><a href=" + fi.Name + ">" + fi.Name + "</a>");       
}

FileInfo is a string array containing all files.

Answer 3

string[] fileNames = Directory.GetFiles(directoryPath, "*", SearchOptions.AllDirectories)

Answer 4

A call to Directory.GetFiles(directoryPath) is what you want. If you want to go deeper into the structure of the path (get files in subfolders, etc) then qualify the call with SearchOptions.AllDirectories, or try looking here
