rows count不是整数的成员

Question

我正在尝试在visual basic上创建DataGridView，但是我遇到了RowsCount的问题。

此代码带有蓝色下划线：

 SQL.SQLDA.Fill(SQL.SQLDS, "GettingInfo").RowsCount 

它说RowsCount is not a member of integer.

这是该流程的所有代码：

      Public Sub LoadBookingData()
    Dim loadSQL As String = "SELECT * FROM booking"
    Dim RowsCount As Integer


    If SQL.SQLCon.State = ConnectionState.Closed Then
        SQL.SQLCon.open()
        SQL.SQLDA.Fill(SQL.SQLDS, "GettingInfo").
        RowsCount = SQL.SQLDS.Tables("GettingInfo").Rows.Count
        If RowsCount < 1 Then
            MsgBox("There is no records", MsgBoxStyle.Critical, "Sorry")
            SQL.SQLDS.Reset()
            SQL.SQLCon.Close()
        Else
            ' there are records !
            DGVData.Rows.Add(RowsCount)
            For i As Integer = 0 To RowsCount - 1
                With DGVData
                    .Rows(1).Cells(0).Value = SQL.SQLDS.Tables("GettingInfo").Rows(i).Item("bookingID")
                    .Rows(1).Cells(0).Value = SQL.SQLDS.Tables("GettingInfo").Rows(i).Item("paymentConfirmation")
                    .Rows(1).Cells(0).Value = SQL.SQLDS.Tables("GettingInfo").Rows(i).Item("totalCost")
                End With
            Next
        End If
        SQL.SQLDS.Reset()
        SQL.SQLCon.Close()

    Else
        ' the connection is already open 
        SQL.SQLDA.Fill(SQL.SQLDS, "GettingInfo").
        RowsCount = SQL.SQLDS.Tables("GettingInfo").Rows.Count
        If RowsCount < 1 Then
            MsgBox("There is no records", MsgBoxStyle.Critical, "Sorry")
            SQL.SQLDS.Reset()
            SQL.SQLCon.Close()
        Else
            ' there are records !
            DGVData.Rows.Add(RowsCount)
            For i As Integer = 0 To RowsCount - 1
                With DGVData
                    .Rows(1).Cells(0).Value = SQL.SQLDS.Tables("GettingInfo").Rows(i).Item("bookingID")
                    .Rows(1).Cells(0).Value = SQL.SQLDS.Tables("GettingInfo").Rows(i).Item("paymentConfirmation")
                    .Rows(1).Cells(0).Value = SQL.SQLDS.Tables("GettingInfo").Rows(i).Item("totalCost")
                End With
            Next
        End If
        SQL.SQLDS.Reset()
        SQL.SQLCon.Close()
    End If
End Sub

这是SQLControl的代码：

    Imports System.Data.SqlClient
    Public Class SQLControl
           Public SQLCon As New SqlConnection With {.ConnectionString = "Data Source=JENNIFER\DDAP2015;Initial Catalog=zachtravelagency;Integrated Security=True;"}
           Private SQLcmd As SqlCommand
           Public SQLDA As SqlDataAdapter
           Public SQLDS As DataSet

有人能指出为什么这么说吗？
