Can someone please help me with the command to hide gridlines when creating an Excel file?

I use the following code :
Code:
  Dim xlApp As Excel.Application
        Dim xlWorkBook As Excel.Workbook
        Dim xlWorkSheet, xlWorkSheet2, xlWorkSheet3 As Excel.Worksheet
        Dim misValue As Object = System.Reflection.Missing.Value

        xlApp = New Excel.ApplicationClass
        xlWorkBook = xlApp.Workbooks.Add(misValue)
        xlWorkSheet = xlWorkBook.Sheets("sheet1")
        xlWorkSheet.Name = "BYLAE A"
        xlWorkSheet2 = xlWorkBook.Sheets.Add
        xlWorkSheet2.Name = "BYLAE B"
        xlWorkSheet3 = xlWorkBook.Sheets.Add
        xlWorkSheet3.Name = "BYLAE C"


And my imports are :

Code:
Imports System.ComponentModel
Imports System.IO
Imports ClosedXML.Excel
Imports HtmlAgilityPack
Imports Microsoft.Office.Interop
Imports MySql.Data.MySqlClient
Imports Z.Dapper.Plus

I would have thought xlWorkSheet.displaygridline = false would do the trick, but it is not recognized as a command
