static void Main(string[] args)
  string _PathFilename = @"C:\Temp\tri_201918.xlsx";
  using (FileStream streamIn = File.Open(_PathFilename, FileMode.Open, FileAccess.Read))
  using (IExcelDataReader execlReader = (Path.GetExtension(_PathFilename) == ".xlsx" ? ExcelReaderFactory.CreateOpenXmlReader(streamIn):               ExcelReaderFactory.CreateBinaryReader(streamIn)))
    DataSet ds = new DataSet();
    ds = execlReader.AsDataSet();

    int r = ds.Tables[0].Rows.Count;
    int c = ds.Tables[0].Columns.Count;
At this point, r has the number of rows and c has the number of columns in sheet 0.
