在asp.net 2.0中發送郵件

作者：webabcd

1、在web.config中的<configuration>內加入如下配置資訊（host—smtp服務地址；port—連接埠號碼；userName—使用者名稱；password—密碼。請自行修改）。

  <system.net>
    <mailSettings>

      <smtp>
        <network host="smtpserver" port="25" userName="uid" password="pwd" />
      </smtp>

    </mailSettings>
  </system.net>

2、aspx頁面HTML代碼    <table border="0">
        <tr>
            <td>
                寄件者
            </td>
            <td>
                <asp:TextBox runat="server" ID="emailfrom"></asp:TextBox>
            </td>
        </tr>
        <tr>
            <td>
                收件者
            </td>
            <td>
                <asp:TextBox runat="server" ID="emailto"></asp:TextBox>
            </td>
        </tr>
        <tr>
            <td>
                主題
            </td>
            <td>
                <asp:TextBox runat="server" ID="subject"></asp:TextBox>
            </td>
        </tr>
        <tr>
            <td>
                附件
            </td>
            <td>
                <asp:FileUpload ID="attachment" runat="server" />
            </td>
        </tr>
        <tr>
            <td>
                內容
            </td>
            <td>
                <asp:TextBox runat="server" ID="body" TextMode="MultiLine" Columns="50" Rows="10"></asp:TextBox>
            </td>
        </tr>
        <tr>
            <td colspan="2" align="center">
                <asp:Button runat="server" ID="btnSend" Text="發送" OnClick="btnSend_Click" />
            </td>
        </tr>
    </table>

3、執行個體化一個MailMessage並設定其屬性        MailMessage mm = new MailMessage(emailfrom.Text, emailto.Text);

        mm.Subject = subject.Text;
        mm.Body = body.Text;
        // HTML格式
        mm.IsBodyHtml = true;

        // 添加附件
        mm.Attachments.Add(new Attachment(attachment.PostedFile.InputStream, attachment.FileName));

        /**//*其他如抄送、優先順序之類的都可以在MailMessage類的屬性中設定*/

4、執行個體化一個SmtpClient，調用其Send方法，參數為MailMessage對象        SmtpClient sc = new SmtpClient();

        // 編程方式設定smtp（不用web.config）
        // sc.Host = "";
        // sc.Port = 25;
        // sc.Credentials = new NetworkCredential("username", "password");

        try
        {
            sc.Send(mm);
            Response.Write("ok");
        }
        catch (Exception ex)
        {
            // 與smtp相關的錯誤
            if (ex is SmtpException)
            {
                // ex.ToString();
                Response.Write("smtp發信失敗");
            }
            else
            {
                Response.Write(ex.ToString());
            }
        }

OK
