WPF Basic Learning Notes Collation (ii) XAML

Basic knowledge:

• Xaml:extensible application Markup Language, Zammel;
• used for instantiation. NET object's markup language ;
• Xmal uses a tree-shaped logical structure to describe the UI;
• Baml:binary application Markup Language, the binary representation of Xmal, VS will convert all XAML to BAML when compiling a WPF application, and BAML will eventually be embedded as a resource in a DLL or EXE assembly;
• BAML is marked, so it is smaller than XAML;
• WPF applications three top-level elements: Window, page, and application;.

• Xmlns= "Http://schemas.microsoft.com/winfx/2006/xaml/presentation"

• The core namespace of WPF, which contains all the WPF classes, including the controls that build the user interface;

• xmlns:x= "Http://schemas.microsoft.com/winfx/2006/xaml"

• A XAML namespace that contains various XAML usage attributes that can affect how the document is interpreted;

• The top two namespaces are namespaces that are formatted by using the URI(Uniform Resource Identifier);

1. The schemas.com domain is owned by Microsoft and is used only by Microsoft, thereby preventing the use of other organizations;
2. The XML namespace used in XAML and the. Net namespace are not one by one counterparts, it is a collection of multiple namespaces, which can be combined into an XML namespace, preventing multiple namespaces from being used in a chaotic environment;

• All the work of the InitializeComponent() method in the window class is to invoke the loadcomponentof the System.Windows.Application class ( ) method, extract BAML from the assembly, build the user interface (create all control objects + set its properties + Associate all event handlers);
