我们正在尝试将 html 字符串的输出发送到特定的测试电子邮件地址,并在运行时发现此错误:
A recipient must be specified.
这是来自代码隐藏文件的编码。
Protected Sub EmailTheList()
' Get the rendered HTML.
'-----------------------
Dim SB As New StringBuilder()
Dim SW As New StringWriter(SB)
Dim htmlTW As New HtmlTextWriter(SW)
GridViewSummary.RenderControl(htmlTW)
' Get the HTML into a string.
' This will be used in the body of the email report.
'---------------------------------------------------
Dim dataGridHTML As String = SB.ToString()
Dim SmtpServer As New SmtpClient()
SmtpServer.Credentials = New Net.NetworkCredential("myEmailAddress@gmail.com", "myPassword")
SmtpServer.Port = 587
SmtpServer.Host = "smtp.gmail.com"
SmtpServer.EnableSsl = True
ObjMailMessage = New MailMessage()
Try
ObjMailMessage.From = New MailAddress("myEmailAddress@gmail.com", "Some text is here.", System.Text.Encoding.UTF8)
ObjMailMessage.Subject = "Test message from Emad"
ObjMailMessage.ReplyToList.Add("john.doe@example.com")
ObjMailMessage.Body = dataGridHTML
ObjMailMessage.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure
SmtpServer.Send(ObjMailMessage)
Catch ex As Exception
MsgBox(ex.ToString())
End Try
End Sub
我们怀疑我们没有为这一行使用正确的语法:
ObjMailMessage.From = ObjMailMessage.ReplyToList.Add("john.doe@example.com")
