如何在 Xamarin.Forms 上发送短信

Question

我正在开发 Xamarin.Forms 项目，iOS、Android 和 Windows Phone。

我的应用要求用户输入短信和 Phone 号码，然后在提交时，我需要向 phone 号码发送短信。

我更喜欢对所有平台使用单一实现。

你可以使用这个开源插件Xam.Plugins.Messaging https://github.com/cjlotz/Xamarin.Plugins

这是提供的例子（来自https://github.com/cjlotz/Xamarin.Plugins/blob/master/Messaging/Details.md）：

// Make Phone Call
var phoneDialer = CrossMessaging.Current.PhoneDialer;
if (phoneDialer.CanMakePhoneCall) 
    phoneDialer.MakePhoneCall("+272193343499");

// Send Sms
var smsMessenger = CrossMessaging.Current.SmsMessenger;
if (smsMessenger.CanSendSms)
   smsMessenger.SendSms("+27213894839493", "Well hello there from Xam.Messaging.Plugin");

var emailMessenger = CrossMessaging.Current.EmailMessenger;
if (emailMessenger.CanSendEmail)
{
    // Send simple e-mail to single receiver without attachments, bcc, cc etc.
    emailMessenger.SendEmail("to.plugins@xamarin.com", "Xamarin Messaging Plugin", "Well hello there from Xam.Messaging.Plugin");

    // Alternatively use EmailBuilder fluent interface to construct more complex e-mail with multiple recipients, bcc, attachments etc. 
    var email = new EmailMessageBuilder()
      .To("to.plugins@xamarin.com")
      .Cc("cc.plugins@xamarin.com")
      .Bcc(new[] { "bcc1.plugins@xamarin.com", "bcc2.plugins@xamarin.com" })
      .Subject("Xamarin Messaging Plugin")
      .Body("Well hello there from Xam.Messaging.Plugin")
      .Build();

    emailMessenger.SendEmail(email);
}

Microsoft 现在在其新的包罗万象的 https://docs.microsoft.com/en-us/xamarin/essentials NuGet 程序包中具有此功能。
