Email 如何从visual basic 2010 professional发送邮件 我想用gmail id发送邮件，我的代码如下，但出现了错误…请帮我解决这个问题。

导入系统.Net 导入System.Net.Mail

公开课表格1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    MsgBox("This will send a mail...")
    Try

        Dim smtpserver As New SmtpClient()
        Dim mail As New MailMessage()
        smtpserver.Credentials = New Net.NetworkCredential("myname@gmail.com", "password")
        smtpserver.Port = 465
        smtpserver.Host = "smtp.gmail.com"
        mail = New MailMessage()
        mail.From = New MailAddress("myname@gmail.com")
        mail.To.Add("to mail id")
        mail.Subject = "Test by bharat"
        mail.Body = "hello ooooooooooooooooooooooo"
        smtpserver.Send(mail)
        MsgBox("Mail Sent")
    Catch ex As Exception
        MsgBox(ex.ToString)
        Close()
    End Try


End Sub

下面的End Class是一个使用visual basic 10发送电子邮件的示例，首先您需要构建一个表单，其中包含字段to、from、text和email\u send按钮，现在是下面的代码

Private Smtp_Server As New SmtpClient()

Private Sub email_send_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles email_send.Click
Try

Dim e_mail As New MailMessage()
Smtp_Server.Credentials = New Net.NetworkCredential("yener.turkeli@v-basic.net", "password")
Smtp_Server.Port = 25
Smtp_Server.Host = "mail.v-basic.net"
e_mail = New MailMessage()
e_mail.From = New MailAddress(from_txt.Text)
e_mail.To.Add(to_txt.Text)
e_mail.Subject = "VB.NET Email Sending"
e_mail.Body = text_txt.Text
Smtp_Server.Send(e_mail)

Catch error_t As Exception
MsgBox(error_t.ToString)
End Try
End Sub

您可以创建一个名为“Mail”的新类。 如果你创建了一个类，如果你想发送一封以上的电子邮件，你不必再次输入所有的代码

Imports System.Net.Mail
Public NotInheritable Class Mail
    Public Property subject As String
    Public Property body As String
    Public Property receiver As String

    Public Sub send()
        Try
            Dim smtpServer As New SmtpClient()
            Dim mail As New MailMessage()
            smtpServer.UseDefaultCredentials = False
            smtpServer.Credentials = New Net.NetworkCredential("yener.turkeli@v-basic.net", "password"))
            smtpServer.Port = 587
            smtpServer.EnableSsl = True
            smtpServer.Host = "smtp.gmail.com"

            mail = New MailMessage()
            mail.From = New MailAddress("yener.turkeli@v-basic.net")
            mail.To.Add(receiver)
            mail.Subject = subject
            mail.Body = body
            smtpServer.Send(mail)
        Catch ex As Exception
            MsgBox(ex.Message & vbNewLine & ex.StackTrace)
        End Try

    End Sub
End Class

然后，您可以在代码中创建一个新对象，在何时何地发送电子邮件：

Dim email as new Mail
email.receiver = "receiver@example.com"
email.subject = "Subject"
email.body = "Message"
email.send()

你有什么错误？？？

Imports System.Net.Mail
Public Class Form1

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click


        Try
            Dim Smtp_Server As New SmtpClient
            Dim e_mail As New MailMessage()
            Smtp_Server.UseDefaultCredentials = False
            Smtp_Server.Credentials = New Net.NetworkCredential("myemail@gmail.com", "Password")
            Smtp_Server.Port = 587
            Smtp_Server.EnableSsl = True
            Smtp_Server.Host = "smtp.gmail.com"

            e_mail = New MailMessage()
            e_mail.From = New MailAddress(TextBox1.Text)
            e_mail.To.Add(TextBox2.Text)
            e_mail.Subject = "Email Sending"
            e_mail.IsBodyHtml = False
            e_mail.Body = txtmsg.Text
            Smtp_Server.Send(e_mail)
            MsgBox("Mail Sent")

        Catch error_t As Exception
            MsgBox(error_t.ToString)
        End Try

    End Sub

End Class
