VB.NET 发送outLook邮件body基于Html样式

首先要添加

 .IsBodyHtml = True

 ''' <summary>
    ''' SFC系统发送邮件
    ''' </summary>
    ''' <param name="MailTitle">邮件标题</param>
    ''' <param name="MailContent">邮件正文</param>
    ''' <param name="SendTypeID">发送类型</param>
    ''' <returns>发送成功返回 True</returns>
    ''' <remarks></remarks>
    Public Function SendMail(MailTitle As String, MailContent As String, SendTypeID As Integer) As Boolean '发送邮件
        SendMail = False
        Try
            Dim client As System.Net.Mail.SmtpClient
            Dim Mailmsg As System.Net.Mail.MailMessage = New System.Net.Mail.MailMessage()
            ' Try
            Mailmsg.From = New System.Net.Mail.MailAddress("sfc@tsmt.com.tw")
           Dim Sql As String = "Select f002 from OP_EMail"
            Dim DT As DataTable = SFCGetDataTable(Sql)
            If DT.Rows.Count > 0 Then
                For i As Integer = 0 To DT.Rows.Count - 1
                    ''收件人列表
                    Mailmsg.To.Add(DT.Rows(i).Item(0).ToString)
                Next

            End If

            With Mailmsg
                .Subject = MailTitle
                .Body = MailContent
                .IsBodyHtml = True　　'不启用的话,Html格式不会显示
            End With
            client = New System.Net.Mail.SmtpClient("spam.tsmt.com.tw")

            client.Send(Mailmsg)
            SendMail = True
            client = Nothing
            Mailmsg.Dispose()
        Catch ex As Exception
            SendMail = False
        End Try
    End Function

           "and  t1.f009<SYSDATE +" & NumericUpDown1.Value & "order by t1.f009"

            Dim dt As DataTable = SFCGetDataTable(sql) '获得岗位证书过期的信息
