【问题描述】:
我正在尝试运行这段代码,将我正在处理的文件导出为 PDF 并使用 gmail 将其通过电子邮件发送给“客户”。 我不断收到消息“发送消息失败”,如果您能对此有所帮助,我们将不胜感激。 出于显而易见的原因,我还故意“*****”了我的电子邮件凭据。
<MiCode(ControlScriptEventType.AfterInkAdded, "Email")> _
Public Sub Ctl_Email_AfterInkAdded(ByVal e As AfterInkAddedEventArgs)
MsgBox("1")
Dim EmailTo As String = _EmailAddress.Value
Dim EmailToName As String = "Client"
Dim EmailFrom As String = "******"
Dim EmailFromName As String = "WHSD"
Dim fileName As String = String.Empty
Dim erl As New System.Collections.Generic.List(Of ExportResult)
For Each er As ExportResult In _form.Validator.ExportResults
erl.Add(er)
fileName = System.IO.Path.GetFileNameWithoutExtension(er.ExpandedFilePath)
Next
Try
Dim fromAddress As New MailAddress(EmailFrom, EmailFromName)
Dim toAddress As New MailAddress(EmailTo, EmailToName)
Using msg As New MailMessage(fromAddress, toAddress)
msg.Body = "This will be the body of the message you are sending." & VbCrLf & "Thank you for your purchase."
msg.Subject = (Me._form.Name & " (" & fileName & ")")
' Add the mail body - an HTML file attached to this form.
For Each attData As AttachmentData In _form.Attachments
If String.Compare(attData.Name, "Lead Generation.html") = 0 Then
msg.Body = System.Text.UTF8Encoding.UTF8.GetChars(attData.BinaryData())
msg.Body = msg.Body.Replace("[filename]", fileName)
End If
Next
' Add pdf/csv file attachments to mail - they are datapaths of the form.
For Each er As ExportResult In erl
If er.Success And ( er.DataPathName = "PDF" Or er.DataPathName = "CSV" ) Then
msg.Attachments.Add(New Attachment(er.ExpandedFilePath))
End If
Next
Dim client As New SmtpClient("aspmx.l.google.com", 25)
'client.EnableSsl = True
'client.Timeout = 10000
client.DeliveryMethod = SmtpDeliveryMethod.Network
client.UseDefaultCredentials = False
client.Credentials = New NetworkCredential("********", "******")
client.Send(msg)
Me.RecordExportResult("Email", True, "Sent email", "Sent email to " & EmailToName & "(" & EmailTo & ")", "")
MsgBox("Sent!")
End Using
Catch ex As Exception
Me.RecordExportResult("Email", False, ex.Message, ex.Message, ex.Message)
MsgBox(ex.Message)
End Try
End Sub

在方法开始处设置断点并单步执行代码。然后您将知道错误在哪一行,从这里您可以找出什么是 Null/不等于它应该是什么。

@Mathemats 不幸的是,我使用的软件没有调试器,我一直在到处放置消息框来测试它,到目前为止它在“For Each er Export...”中中断。代码块
