Three ways to get all the file names under the specified folder

Returns the path that contains the file name. and then intercept the filename.

Such as:

string[] Filenames=directory.getfiles (path);
For (string files in filenames)
{
Response.Write (Files.replace (Path, ""));
}

Method Two:

DirectoryInfo dir = new DirectoryInfo (@ "C:data");
fileinfo[] Finfo = Dir.getfiles ();
string fnames = String.Empty;
for (int i = 0;   i < finfo.length; i++)
{
Fnames + + finfo[i].name + "<br>";
}
Response.Write (Fnames);
