Simple enough to do, as long as you remember you have to remove it from the parent item’s children list.

public static void DeleteMetabaseObject(string metabasePath)
 {  try
  {
   string deleteParent = metabasePath.Substring(0,metabasePath.LastIndexOf("/"));
   string deleteName = metabasePath.Substring(metabasePath.LastIndexOf("/") + 1);
   DirectoryEntry parent = new DirectoryEntry(deleteParent);
   DirectoryEntry childToDelete = new DirectoryEntry(metabasePath);
   parent.Children.Remove(childToDelete);
   parent.CommitChanges();
  }
  catch(System.Runtime.InteropServices.COMException e1)
  {
   throw e1;
  }
}
