在Windows Universal App中发送电子邮件

Question

是否可以在适用于Windows 8.1和Windows Phone 8.1的Windows Universal App中发送电子邮件？

await Launcher.LaunchUriAsync(new Uri("mailto:abc@abc.com?subject=MySubject&body=MyContent"));

使用此代码行,我可以发送电子邮件,但我想发送带附件的邮件.

由于Microsoft错过了将EmailMessage和EmailManager添加到Windows应用商店库中,似乎只有两个不令人满意的解决方案:您可以使用共享或通过mailto协议发起电子邮件发送.我是这样做的:

  /// <summary>
  /// Initiates sending an e-mail over the default e-mail application by 
  /// opening a mailto URL with the given data.
  /// </summary>
  public static async void SendEmailOverMailTo(string recipient, string cc, 
     string bcc, string subject, string body)
  {
     if (String.IsNullOrEmpty(recipient))
     {
        throw new ArgumentException("recipient must not be null or emtpy");
     }
     if (String.IsNullOrEmpty(subject))
     {
        throw new ArgumentException("subject must not be null or emtpy");
     }
     if (String.IsNullOrEmpty(body))
     {
        throw new ArgumentException("body must not be null or emtpy");
     }

     // Encode subject and body of the email so that it at least largely 
     // corresponds to the mailto protocol (that expects a percent encoding 
     // for certain special characters)
     string encodedSubject = WebUtility.UrlEncode(subject).Replace("+", " ");
     string encodedBody = WebUtility.UrlEncode(body).Replace("+", " ");

     // Create a mailto URI
     Uri mailtoUri = new Uri("mailto:" + recipient + "?subject=" +
        encodedSubject +
        (String.IsNullOrEmpty(cc) == false ? "&cc=" + cc : null) +
        (String.IsNullOrEmpty(bcc) == false ? "&bcc=" + bcc : null) +
        "&body=" + encodedBody);

     // Execute the default application for the mailto protocol
     await Launcher.LaunchUriAsync(mailtoUri);
  }

要发送带有附件的电子邮件，您需要使用EmailMessage和EmailManager类。

1. 邮件留言：

EmailMessage 类定义将发送的实际电子邮件。您可以指定电子邮件的收件人（收件人、抄送、BC）、主题和正文。

2. 电子邮件管理器：

EmailManager 类在 Windows.ApplicationModel.Email 命名空间中定义。EmailManager 类提供了一个静态方法 ShowComposeNewEmailAsync，它接受 EmailMessage 作为参数。ShowComposeNewEmailAsync 将启动带有 EmailMessage 的撰写电子邮件屏幕，允许用户发送电子邮件。
