Question

如何使用按钮在Windows Phone 8.1 app中发送电子邮件？

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);

我收到错误说：

＆＃34;错误1＆＃39; await＆＃39;运算符只能在异步方法中使用。考虑使用＆＃39; async＆＃39;标记此方法。修饰和改变它的返回类型为＆＃39;任务＆＃39;。＆＃34;

您需要使用async关键字标记您的事件处理程序，以便能够在其中await：

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);
}
