Windows Phone開發（24）：啟動器與選取器之傳送簡訊

本節我們通過一個簡單的傳送簡訊樣本來示範一下如果配合使用PhoneNumberChooserTask和SmsComposeTask類。

PhoneNumberChooserTask是選取器，它用於從你的電話簿裡選擇你要傳送簡訊的電話號碼；

SmsComposeTask就是用來啟動傳送簡訊組件並顯示發送視窗。

注意，這些操作都在使用者的操控之中，傳送簡訊一定會顯示可視化頁面的，而且不會偷偷地在後台發送，因為Windows phone是以使用者體驗和安全為原則的，後台發送是不允許的，而且發送過程是由使用者控制的，你可以選擇取消或退出。

SmsComposeTask類的To屬性就是目標電話號碼，Body就是你要發送的簡訊的本文。

同樣，你會很輕鬆地就完成這個任務，不信，看看代碼吧。
