注解

重要

若要在应用中实现Windows 10或更高版本的搜索，请使用 AutoSuggestBox。 有关详细信息 ，请参阅自动建议框 。

不应在适用于 Windows 10 或更高版本的应用中使用 Windows.ApplicationModel.Search API (SearchPane、 SearchContract) 或 SearchBox API。

注意

应用不能同时使用搜索框 (Windows.UI.Xaml.Controls.SearchBox/WinJS.UI.SearchBox) 和 SearchPane。 在同一应用中同时使用搜索框和搜索窗格会导致应用引发异常，并显示以下消息：“无法创建类型为'Windows.UI.Xaml.Controls.SearchBox'的实例。

可以使用占位符文本向用户指示他或她可以搜索的内容。

如果占位符文本太长，无法容纳在搜索框中，系统会截断文本，而不会引发异常。
