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。

我的应用程序要求用户输入短信和电话号码，然后提交，我需要发送短信到电话号码。

我更喜欢所有平台都有一个实现。

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

这是所提供的例子（从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); 
}
