Easy Question, Delete all files in a path then recreate the path.

Hello,

Just an easy question for someone, not for me cause I don't know why it doesn't work, so if anyone could amend this please help:

  if (!Directory.Exists(path))
                 {                  
                       Directory.CreateDirectory(path);
                 }
                 else {
 
                      var hi = Directory.GetFiles(path);
 
                     for (int i = 0; i < hi.Length; i++) {
                         File.Delete(hi[i]);
                     }
 
                     Directory.Delete(path);
                     Directory.CreateDirectory(path);
                 }
