关于System.Net.Mail的帮助

Question

我正在尝试从我的网页发送电子邮件，所以我尝试了一下：

Imports System.Net.Mail

Dim mSmtpClient As SmtpClient
Dim MMsg As MailMessage

Sub SendEmail()
        MMsg = New MailMessage()

        MMsg.From = New MailAddress(txtFrom.Text)
        MMsg.To.Add(txtTo.Text)

        MMsg.Subject = txtSubject.Text
        MMsg.Body = txtBody.Text

        MMsg.IsBodyHtml = True
        MMsg.Priority = MailPriority.Normal

        mSmtpClient = New SmtpClient("host_name_goes_here")
        mSmtpClient.Send(MMsg)
End Sub

但这是行不通的。我一直收到以下错误：

Type 'SmtpClient' is not defined.

Line 7: Dim mSmtpClient As SmtpClient

有人知道我做错了什么吗？

我已经看过了：

但似乎找不到答案。

Answer 1

这是新的代码。

Dim mSmtpClient As New SmtpClient
Dim MMsg As New MailMessage

Sub SendEmail()
    MMsg = New MailMessage()

    MMsg.From = New MailAddress(txtFrom.Text)
    MMsg.To.Add(txtTo.Text)

    MMsg.Subject = txtSubject.Text
    MMsg.Body = txtBody.Text

    MMsg.IsBodyHtml = True
    MMsg.Priority = MailPriority.Normal

    mSmtpClient = New SmtpClient("host_name_goes_here")
    mSmtpClient.Send(MMsg)
End Sub

您的代码需要在容器中，如类或模块。所以试试这个：

Imports System.Net.Mail

public module mymail

    Dim mSmtpClient As SmtpClient
    Dim MMsg As MailMessage

    Sub SendEmail()
        MMsg = New MailMessage()

        MMsg.From = New MailAddress(txtFrom.Text)
        MMsg.To.Add(txtTo.Text)

        MMsg.Subject = txtSubject.Text
        MMsg.Body = txtBody.Text

        MMsg.IsBodyHtml = True
        MMsg.Priority = MailPriority.Normal

        mSmtpClient = New SmtpClient("host_name_goes_here")
        mSmtpClient.Send(MMsg)
    End Sub
end module

如果你愿意，你也可以使用一个类。
