As per your code, you are trying to search the file names in the given directory .,

for this you can use the below code.

string[] files = Directory.GetFiles(Server.MapPath("files/"), "*.*");

Second Argument can be any wild card.

Ex :

string[] files = Directory.GetFiles(Server.MapPath("files/"), "A*.*");

files start with "A"

string[] files = Directory.GetFiles(Server.MapPath("files/"), "ABC?.*");

Files Start with "ABC" and ends with any character.

string[] files = Directory.GetFiles(Server.MapPath("files/"), "ABC DEF*.*");

Files Start with "ABC DEF" and ends with any characters.

Hope this helps you.
