UWP EmailMessage linebreak/new 行?

UWP EmailMessage linebreak/new line?

我正在寻找一种在我的 UWP 应用中 EmailMessage() 正文中放置换行符的方法。

我已经尝试过 "\n"\r\nEnvironment.NewLine<br><br />,每次它都被省略,无论是在桌面上,还是在移动或两者兼而有之。我尝试使用 Outlook 和 Gmail。

我正在使用 VS2015 更新 3。

谢谢。

编辑:这是代码

    public static async Task ComposeEmail(string address, string messageSubject, StorageFile attachmentFile)
    {
        var emailMessage = new EmailMessage();
        emailMessage.Subject = messageSubject;

        var lineBreak = Environment.NewLine;
        string body = lineBreak + lineBreak + lineBreak + lineBreak + lineBreak + lineBreak + textLoader.GetString("EmailPleaseDontCut") + lineBreak + Info.GetAllInfos();
        emailMessage.Body = body;

        if (attachmentFile != null)
        {
            var stream = Windows.Storage.Streams.RandomAccessStreamReference.CreateFromFile(attachmentFile);

            var attachment = new EmailAttachment(attachmentFile.Name, stream);

            emailMessage.Attachments.Add(attachment);
        }

        emailMessage.To.Add(new EmailRecipient(address));

        await EmailManager.ShowComposeNewEmailAsync(emailMessage);
    }

我正在显示这样一封电子邮件,它在正文中将其分成两行

 EmailMessage emailMessage = new EmailMessage()
 {
       Subject = "App Feedback " + Package.Current.DisplayName + " " + ApplicationServices.CurrentDevice,
       Body = "First Line\r\nSecondLine" 
 };

 emailMessage.To.Add(new EmailRecipient() { Address = "admin@DotNetRussell.com" });
 await EmailManager.ShowComposeNewEmailAsync(emailMessage);

我想我读了关于在 UWP 中发送电子邮件的同一篇文章。您发布的代码看起来与它相同。那个例子很糟糕而且是错误的。我发布的方式效果更好。
