为什么有些数据没有发送到 email？

Question

我有以下代码在 mail.Body 上发送mail.Body

  Private Sub SendMessage()
        Dim mail As MailMessage = New MailMessage

        mail.From = New MailAddress("example1@gmail.com")
        mail.To.Add(New MailAddress("example2@gmail.com"))

        mail.Subject = "TEST SUBJECT"

       mail.Body = "<br/><br/>Employee No : " & lblEmpNO.Text.Replace(Environment.NewLine, "<br />") & "<br/><br/>Employee Name : " & lblemployeename.Text.Replace(Environment.NewLine, "<br />") & "<br /><br />Employee Department : " & lbldepartment.Text.Replace(Environment.NewLine, "<br />") &
                    "<br/><br/>Date From : " & datepickerFrom.Text.Replace(Environment.NewLine, "<br>/") & " <br/><br/>Date To : " & datepickerto.Text.Replace(Environment.NewLine, "<br/>") & "<br/><br/>Reason : " & comboboxReason.Text.Replace(Environment.NewLine, "<br/>") & "<br/><br/>Remarks : " & txtRemark.Text.Trim

        mail.IsBodyHtml = True
        Dim client As New SmtpClient()
        client.EnableSsl = True
        Try
            client.Send(mail)
            'MsgBox("Sending Email succeeded")
        Catch ex As Exception
            'MsgBox("Sending Email failed. Please try again")
        End Try
    End Sub

但由于某种原因， Date From ， Date To ， Reason和Remarks不发送任何数据。

这是我得到的 output：
