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。

我参考了很多例子，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>"

Answer 2

您在使用 html 模板吗？

试试

strbody = strbody & "Thank you and have a wonderful day. <br>" 

或\n

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