Use Tuple to send Excel Column headers and data row from same function using VB.net

Public Function ReadXcel(fileName As String, sheetName As String, tblName As String) As Tuple(Of DataTable, List(Of String))
	Dim connectionString = (Convert.ToString("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=") & fileName) + ";Extended Properties=Excel 12.0;"
	Dim adapter = New OleDbDataAdapter((Convert.ToString("SELECT * FROM [") & sheetName) + "]", connectionString)
	Dim ds = New DataSet()
	adapter.Fill(ds, tblName)

	Dim dt = ds.Tables(tblName)

	Dim excelColumnHeaders = dt.Columns.Cast(Of DataColumn)().[Select](Function(x) x.ColumnName).ToList()

	Return Tuple.Create(dt, excelColumnHeaders)
End Function
