如何在Windows phone 8.1应用程序中使用按钮发送电子邮件?

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);

我得到错误说:

"Error 1 'await'操作符只能在async方法中使用。考虑使用'async'修饰符标记此方法并进行更改它的返回类型为'Task'。"

您需要用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);
}
