使用过时的 System.Web.Mail 发送电子邮件工作正常，这是代码片段：

 Public Shared Sub send(ByVal recipent As String, ByVal from As String, ByVal subject As String, ByVal body As String)
        Try
            Dim Message As System.Web.Mail.MailMessage = New System.Web.Mail.MailMessage
            Message.To = recipent
            Message.From = from
            Message.Subject = subject
            Message.Body = body
            Message.BodyFormat = MailFormat.Html
            Try
                SmtpMail.SmtpServer = MAIL_SERVER
                SmtpMail.Send(Message)
            Catch ehttp As System.Web.HttpException
                critical_error("Email sending failed, reason: " + ehttp.ToString)
            End Try
        Catch e As System.Exception
            critical_error(e, "send() in Util_Email")
        End Try
    End Sub

这是更新的版本：

Dim mailMessage As New …

我正在创建一个Double类型的双向链表,无论我如何声明另一个相同类型的链表,它总是引用第一个列表.

如:

LinkedList<LinkedList<Double>> trainingData = new LinkedList<LinkedList<Double>>();
LinkedList<LinkedList<Double>> newData = new LinkedList<LinkedList<Double>>();

添加一些东西到trainingData ...

newData = trainingData;  

然后,在newData中更改此赋值后,我对trainingData所做的任何更改.我也尝试在newData的构造函数中传递trainingData,并使用嵌套循环将trainingData的数据分配给newData,但它仍然给我相同的结果,其中newData引用trainingData.
