ขอวิธีนำค่าใน textbox ไปออกรายงานใน crystal report ใน C# หน่อยครับ

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim dw As New DataSet1TableAdapters.roomTableAdapter
        Dim dt As New DataTable
        dt = dw.GetData()
        Dim report As New CrystalDecisions.CrystalReports.Engine.ReportDocument()
        Dim crConnection As New ConnectionInfo
        With crConnection
            .ServerName = "BOOMNA"
            .DatabaseName = "apartmentbase"
            .UserID = "sa"
            .Password = ""
            .IntegratedSecurity = "true"
        End With
        report.Load(Server.MapPath("debit.rpt"))
        report.SetDataSource(dt)
        report.SetParameterValue("roomid", TextBox1.Text)
        CrystalReportViewer1.ReportSource = report
End Sub
