vb.net - 电子邮件换行符不起作用

Question

我正在尝试在自动电子邮件正文中强制换行。

我引用了很多例子，比如"Adding multiple lines to body of SMTP email VB.NET" .

我尝试了许多不同的换行方式:

1. StringBuilder.AppendLine

   Dim sb As New StringBuilder
   sb.AppendLine("For security purposes, only the password will be provided within this email.")
   sb.AppendLine("Thank you and have a wonderful day.")
   

2. System.Environment.NewLine

   strbody = strbody & "Thank you and have a wonderful day. " & System.Environment.NewLine
   strbody = strbody & "Password: " & Dsa.Tables(0).Rows(0).Item(2) & System.Environment.NewLine & System.Environment.NewLine
   

3. vbNewLine

   strbody = strbody & "Thank you and have a wonderful day. " &  vbNewLine
   

4. vbCrLf

   strbody = strbody & "Thank you and have a wonderful day. " & vbCrLf
   

5. Environment.NewLine

   strbody = strbody & "Thank you and have a wonderful day. " & Environment.NewLine
   

以此类推，但每次收到邮件时都没有换行符。

还有其他版本我可以测试吗？

Dim strbody As String

Try

    Dim strTo As String

     strbody = ""
    strbody = strbody & "Thank you for contacting us to gain account access. " & vbNewLine
    strbody = strbody & "You requested your password for the Applicaton registration site. " & vbNewLine
    strbody = strbody & "For security purposes, only the password will be provided within this email. " & vbNewLine
    strbody = strbody & "Thank you and have a wonderful day. " & vbNewLine
    strbody = strbody & "Password: " & Dsa.Tables(0).Rows(0).Item(2) & System.Environment.NewLine & vbNewLine & vbNewLine
    strbody = strbody & "If you didn't request your password, please notify from@location.com of your concern "


    strTo = Dsa.Tables(0).Rows(0).Item(1)
    Dim msg As New System.Net.Mail.MailMessage("from@we-location.com", strTo, "Retrive Your Password", strbody)

    Dim smtp As New System.Net.Mail.SmtpClient


    msg.IsBodyHtml = True
    smtp.Host = "mailhost.location.com"
    smtp.Send(msg)

Catch ex As Exception

End Try

Answer 1

这里的关键代码行是这样的:

msg.IsBodyHtml = True

由于您要发送 HTML 电子邮件，因此您必须使用 HTML 标记来创建换行符。

strbody = strbody & "Thank you for contacting us to gain account access. <br><br>"
