WP8.1StoreApp(WP8.1RT)---发送邮件和短信

在WP7/8中，发送短信是利用了EmailComposeTask和SmsComposeTask来实现的。

在WP8.1 Store App中，原来的方式已经失效，采用了新的方法：ChatMessageManager和EmailManager管理和发送信息。

简单使用：

private async void SendSmsTask(string body,string phoneNum)
{
    var chatMessage = new Windows.ApplicationModel.Chat.ChatMessage();
    chatMessage.Body = body;
    chatMessage.Recipients.Add(phoneNum);
    await ChatMessageManager.ShowComposeSmsMessageAsync(chatMessage);
}
private async void SendEmailTask(string body, string emailAddress)
{
    var emailMessage = new EmailMessage();
    emailMessage.Body = body;
    emailMessage.To.Add(new EmailRecipient(emailAddress));
    await EmailManager.ShowComposeNewEmailAsync(emailMessage);
}

msdn的介绍:

private async void ComposeSms(Windows.ApplicationModel.Contacts.Contact recipient,string messageBody,StorageFile attachmentFile,string mimeType)
{
    var chatMessage = new Windows.ApplicationModel.Chat.ChatMessage();
    chatMessage.Body = messageBody;

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

        var attachment = new Windows.ApplicationModel.Chat.ChatMessageAttachment(
            mimeType,
            stream);

        chatMessage.Attachments.Add(attachment);
    }

    var phone = recipient.Phones.FirstOrDefault<Windows.ApplicationModel.Contacts.ContactPhone>();
    if (phone != null)
    {
        chatMessage.Recipients.Add(phone.Number);
    }
    await Windows.ApplicationModel.Chat.ChatMessageManager.ShowComposeSmsMessageAsync(chatMessage);
}

private async void ComposeEmail(Windows.ApplicationModel.Contacts.Contact recipient,string messageBody,StorageFile attachmentFile)
{
    var emailMessage = new Windows.ApplicationModel.Email.EmailMessage();
    emailMessage.Body = messageBody;

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

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

        emailMessage.Attachments.Add(attachment);
    }

    var email = recipient.Emails.FirstOrDefault<Windows.ApplicationModel.Contacts.ContactEmail>();
    if (email != null)
    {
        var emailRecipient = new Windows.ApplicationModel.Email.EmailRecipient(email.Address);
        emailMessage.To.Add(emailRecipient);
    }

    await Windows.ApplicationModel.Email.EmailManager.ShowComposeNewEmailAsync(emailMessage);

}
