WP 8.1运行时代码,用于拨打电话,发送短信和发送电子邮件(不是Silverlight 8.1)

Question

我正在编写一个应用程序,可以拨打电话,发送短信或电子邮件,就像wp 8.1中的People应用程序一样.到目前为止,我已经找到一个msdn的链接表单,其中说"适用于:Windows Phone 8和Windows Phone Silverlight 8.1".所以这里的代码:来自这个链接

using Microsoft.Phone.Tasks;

private void TextBlock_Tapped_Call(object sender, TappedRoutedEventArgs e)
{
    PhoneCallTask phoneCallTask = new PhoneCallTask();
    phoneCallTask.PhoneNumber = "2065550123";
    phoneCallTask.DisplayName = "Gage";

    phoneCallTask.Show();
}

但是我收到了一个错误:

名称空间"Microsoft"中不存在类型或命名空间名称"Phone"(您是否缺少程序集引用？)

编辑:很抱歉有一个重复的问题,同样在这里:在Windows Phone 8.1中拨打电话 回答@Chris Shao,他还更新了代码以发送短信和电子邮件.

Answer 1

如果要使用Microsoft.Phone.Tasks,则必须创建Windows Phone Silverlight 8.1项目.如果您的项目是Windows Phone 8.1,

您可以使用此代码拨打电话:

Windows.ApplicationModel.Calls.PhoneCallManager.ShowPhoneCallUI("phone number", "display name");

并用它来发送短信:

Windows.ApplicationModel.Chat.ChatMessage msg = new Windows.ApplicationModel.Chat.ChatMessage();
msg.Body = "This is body of demo message.";
msg.Recipients.Add("10086");
msg.Recipients.Add("10010");
await Windows.ApplicationModel.Chat.ChatMessageManager.ShowComposeSmsMessageAsync(msg);

并用它来发送邮件:

Windows.ApplicationModel.Email.EmailMessage mail = new Windows.ApplicationModel.Email.EmailMessage();
mail.Subject = "This is Subject";
mail.Body = "This is body of demo mail";
mail.To.Add(new Windows.ApplicationModel.Email.EmailRecipient("shaom_wp@hotmail.com", "shaomeng"));
await Windows.ApplicationModel.Email.EmailManager.ShowComposeNewEmailAsync(mail);
