Bit crude, but take a look at the following code:

private void splitIt(string theQuery)
{
   List<string> theList = new List<string>();
   string[] theS = theQuery.Split(' ');
   StringBuilder s = new StringBuilder();
   foreach (var item in theS)
   {
      if ((item == "CREATE") || (item == "INSERT"))
      {
         if (s.ToString().Count() > 0)
         {
            theList.Add(s.ToString());
            s.Remove(0, s.Length);
            s.Append(item + " ");
         }
         else
            s.Append(item + " ");
      }
      else
      {
         s.Append(item + " ");
      }
   }
   theList.Add(s.ToString());
   string[] arr = theList.ToArray();
}

Pass your Datafile as theQuery parameter.
