Windows.UI.Xaml.Controls.SearchBox在哪里？

Question

I can't add using Windows.UI.Xaml.Controls.SearchBox; to my Windows Store Application. Visual Studio doesn't seem to know what I'm talking about. It tells me that it doesn't exist in the namespace.

Answer 1

A namespace is a collection of classes, to use one of the classes you need to reference the respective namespace.

Windows.UI.Xaml.Controls is namespace

SearchBox is a class

You need to add reference of Windows.UI.Xaml.Controls :

using Windows.UI.Xaml.Controls;

and create an object of Windows.UI.Xaml.Controls.SearchBox :

Windows.UI.Xaml.Controls.SearchBox sbox = new Windows.UI.Xaml.Controls.SearchBox();
this.Controls.Add(sbox); //this line will add it to your app page controls list

Here is the list of controls available in Windows.UI.Xaml.Controls namespace.
