Try:

foreach (string file in System.IO.Directory.GetFiles(a))

{

   string asd = Path.GetFileNameWithoutExtension(file);

   string[] str = asd.Split('_');

   string sam1 = str[0];

   string sam2 = str[1];

   if(!combo1.Items.Contains(sam1)) combo1.Items.Add(sam1);

   if(!combo2.Items.Contains(sam2)) combo2.Items.Add(sam2);
