c# - WP 8.1 运行时代码，用于调用电话、发送短信和发送电子邮件(不是 Silverlight 8.1)

Question

我正在编写一个可以调用电话、发送短信或电子邮件的应用程序，就像 wp 8.1 中的 People 应用程序一样。到目前为止，我已经找到了一个链接表单 msdn，上面写着“适用于:Windows Phone 8 和 Windows Phone Silverlight 8.1”。所以这里的代码:from this link

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();
}

但是我得到一个错误:

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

编辑:抱歉重复的问题，同样在这里:Make a phone call in Windows Phone 8.1@Chris Shao 的回答，他还更新了发送短信和电子邮件的代码。

Answer 1

如果您想使用 Microsoft.Phone.Tasks，您必须创建 Windows Phone Silverlight 8.1 项目。如果您的项目是 Windows Phone 8.1，

您可以使用此代码调用电话:

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);
