Three methods to obtain the names of all objects in a specified folder

Returns the path containing the file name, and then truncates the file name.

For example:

String [] filenames = directory. getfiles (path );
For (string files in filenames)
{
Response. write (files. replace (path ,""));
}

Method 2:

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 );

Method 3
