// Delete files on the server:
DirectoryInfo di = new DirectoryInfo(Server.MapPath("~/Data"));
FileInfo[] files = di.GetFiles();
foreach (FileInfo file in files)
{
    file.Delete();
}
 
// Delete files on the client's machine
// will lead to a serious security breach
// NO GO

cdaly33: your code will cause issues:
string[] files = IO.Directory.GetFiles("path with files to delete");

Gives the error:
Cannot convert source type System.IO.FileInfo[ ] to target type string[ ]

Delete all files:

using System.IO;

string[] filePaths = Directory.GetFiles(@"c:\MyDir\");
foreach (string filePath in filePaths)
  File.Delete(filePath);

OR

Delete all files (one-row example):

Array.ForEach(Directory.GetFiles(@"c:\MyDir\"),
              delegate(string path) { File.Delete(path); });
