很多時候，我們對用戶的操作或輸入做一定程度的限制，以避免發生不必要的異常或錯誤，因此，對一些特殊的類型，進行輸入限制是很有必要的。
通改變屏幕鍵盤的顯示模式可以規范和告訴用戶， 這里應該輸入什么。
要做到這些并不復雜，只要用到一個類就足矣—— InputScope，它有一個Names屬性，包含InputScopeName列表，而InputScopeName的NameValue是一個枚舉值，說到底，顯示什么樣的屏幕鍵盤就取決于該枚舉值。
?
非常多的內容，至少每個枚舉項表示什么，就沒有必要一一說明，大家參考SDK文檔就可以了。
?
上面是理論部分，是不是這么神呢，下面我們用實踐來證明吧。

啟動你的VS，然后新建一個Silverlight for Windows Phone應用項目。
界面很簡單，隨便放幾個TextBox，我們只做幾個典型的應用就行了，因為原理都是一樣的。比如數字，日期，時間，Email地址等。

當然了，這種限制并不能十分準確，所以在你應用程序中，確認的時候也應當對特定的數據類型進行多一次驗證。
