c# - 在 Windows 中的 Windows 移动应用程序中发送邮件

Question

我是 Windows Mobile 应用程序的新手。在我的项目中，我想使用 microsoft.windowsmobile.pocketoutlook 发送电子邮件。到目前为止，我有以下代码:

private void btnsubmit_Click(object sender, EventArgs e)
{
    try
    { 
        totleave();
        OutlookSession ol = new OutlookSession();
        EmailMessage em = new EmailMessage();
        //Recipient  s1 = em.From;
        //Console.WriteLine(s1);
        Recipient r = new Recipient("iyalarasi.r", "iyalarasi.r@winxsolutions.com");
        em.To.Add(r);
        em.Subject = "Request For Leave";
        em.BodyText =txtename.Text +"(Emp id:"+txteno.Text+ ")" + " request "+ cb1.SelectedItem.ToString()+" leave from "+dtpfrom .Value
            .ToShortDateString ()+" to "+dtpto .Value.ToShortDateString ()  + "\n The reason is " + txtreason.Text;
        EmailAccount ea = ol.EmailAccounts[0];
        ea.Send(em);
        // em.Send("iyalarasi.r");//Account name in outlook
        //MessagingApplication.Synchronize("iyalarasi.r");
        MessageBox.Show("mail sent");
        f2.Show();
        f2.lblmsg.Text = "You have Applied Leave";
    }
    catch (PocketOutlookException ex)
    {
        lblmsg1.Text = ex.ToString();
    }
    catch (Exception e1)
    {
        lblmsg1.Text = e1.ToString();
    }
}

使用此代码，电子邮件会出现在发件箱中，但绝不会出现在收件箱中。使用 Gmail，它显示以下消息:

Messages could not be sent. Check that you have network coverage, and that your account information is correct, and then try again.

我的帐户信息是正确的。这是怎么回事？

Answer 1

我已经使用 POOM 从 Windows Mobile 设备发送电子邮件:

我使用代码遍历可用的 Outlook 电子邮件帐户。字符串 sMailAccount 具有 pocketOutlook 中显示的帐户名称，例如“Google Mail”:

sendMail类的类代码...

    public sendMail(string sMailAccount)
    {
        session = new OutlookSession();
        //eMail = new EmailMessage();
        bool bFound = false;
        foreach (Account acc in session.EmailAccounts)
        {
            System.Diagnostics.Debug.WriteLine(acc.Name);
            if (acc.Name == sMailAccount)
                bFound = true;
        }
        if (bFound)
            account = session.EmailAccounts[sMailAccount];
        if (account != null)
            _bIsValidAccount = true;
    }
    ...

我的代码用于向收件人发送图像:

    public bool send(string sImagePath)
    {
        if (account == null)
            return false;
        try
        {
            eMail = new EmailMessage();
            rcp = new Recipient(_to);
            eMail.To.Add(rcp);
            eMail.Subject = "Visitenkarten";
            eMail.BodyText = "VCard " + DateTime.Now.ToShortDateString() + " " + DateTime.Now.ToShortTimeString() + "\r\nsent from eMDI2Mail";

            attachement = new Attachment(sImagePath);
            eMail.Attachments.Add(attachement);                
            eMail.Send(account);                
            //account.Send(eMail);
            if (this._syncImmediately)
            {
                if (this.account != null)
                    Microsoft.WindowsMobile.PocketOutlook.MessagingApplication.Synchronize(this.account);
            }
            return true;
        }
        catch (Exception ex)
        {
            System.Diagnostics.Debug.WriteLine("Exception in send(): " + ex.Message);
        }
        return false;
    }

另一个需要了解的问题是 POutlook 不会立即发送消息。为此，我引入了一个名为 _syncImmediately 的变量。如果是这样，Outlook 将立即发送邮件。如果没有，我提供另一个名为 syncNow() 的函数:

    /// <summary>
    /// sync eMail in outlook
    /// </summary>
    /// <param name="pHandle">handle to forground window</param>
    public void syncNow(IntPtr pHandle)
    {
        if (this.account != null)
        {
            Microsoft.WindowsMobile.PocketOutlook.MessagingApplication.Synchronize(this.account);
            SetForegroundWindow(pHandle);
        }
    }

SetForeGroundWindow() 用于将我们带回应用程序。

这是全类:

如您所见，该类还能够通过给定的 XML WAP 配置文件创建电子邮件帐户。

顺便说一句:该应用程序旨在使用 Intermec eMDI 技术在展会上制作一张特殊的名片照片。然后这些应该直接发送给秘书以创建这些线索。

OK，为了更简单明了:1. 为了能够使用 POutlook，您需要引用 poutlook session 。2. 为了能够通过代码发送电子邮件，您需要指定poutlook 必须使用的邮件帐户。3. 然后创建一个电子邮件对象并填写字段4.最后使用email对象的send方法与已有的account对象

更详细

创建 session 对象

      OutlookSession session = new OutlookSession();

指定用于发送电子邮件的帐户。字符串必须与您定义的完全匹配PocketOutlook 电子邮件帐户名称。如果你用一个数字作为引用，你不能确定，哪个选择帐户。

      EmailAccount account = session.EmailAccounts[sMailAccount];

检查返回的帐户。它是空的吗？现在创建一个新的 EMailMessage(与 TextMessage(SMS) 对比)

      EmailMessage eMail = new EmailMessage();

然后填写EmailMessage对象的字段

        Recipient rcp = new Recipient(_to);
        eMail.To.Add(rcp);
        eMail.Subject = "Visitenkarten";
        eMail.BodyText = "Enter some eMail text to send";

最后发送邮件:

     eMail.Send(account); 

由于 poutlook 通常会定期在后台发送电子邮件，您可能希望让poutlook 立即发送邮件。如果是这样，您可以使用该代码:

     Microsoft.WindowsMobile.PocketOutlook.MessagingApplication.Synchronize(account);

这将使poulook立即同步指定帐户的电子邮件，同时也带来了前景窗口到前景。

这是否简单明了？
