电子邮件撰写任务无法正常工作Windows Phone 8.1

Question

how to send email in windows phone 8.1 app using a button ?

EmailRecipient sendTo = new EmailRecipient()
{
    Address = "abc@outlook.com"
};

//generate mail object
EmailMessage mail = new EmailMessage();
mail.Subject = "Feedback";


//add recipients to the mail object
mail.To.Add(sendTo);
//mail.Bcc.Add(sendTo);
//mail.CC.Add(sendTo);

//open the share contract with Mail only:
await EmailManager.ShowComposeNewEmailAsync(mail);

I'm getting error saying:

"Error 1 The 'await' operator can only be used within an async method. Consider marking this method with the 'async' modifier and changing its return type to 'Task'."

Answer 1

You need to mark your event handler with the async keyword to be able to await inside it:

public async void MyButtonHandler(object sender, EventArgs e)
{
   EmailRecipient sendTo = new EmailRecipient()
   {
       Address = "abc@outlook.com"
   };

   //generate mail object
   EmailMessage mail = new EmailMessage();
   mail.Subject = "Feedback";

   //add recipients to the mail object
   mail.To.Add(sendTo);
   //mail.Bcc.Add(sendTo);
   //mail.CC.Add(sendTo);

   //open the share contract with Mail only:
   await EmailManager.ShowComposeNewEmailAsync(mail);
}
