Sets or returns the first page number for the printed worksheet. By default, the first page number will be 1, or, if the print job does not start with page 1, this will be the number of the first page in the sequence of pages to print. Setting this property will set the FirstPageNumberAuto property to false.

public int FirstPageNumber{ get; set; }
Public Property FirstPageNumber() As Integer
 
          //--- Get FirstPageNumber
          int firstPage = ps.FirstPageNumber;

          //--- Set FirstPageNumber
          ps.FirstPageNumber = 3;
        
          '--- Get FirstPageNumber
          Dim firstPage As Integer = ps.FirstPageNumber

          '--- Set FirstPageNumber
          ps.FirstPageNumber = 3
