Uri Class
namespace Noesis | MSDN
Provides a representation of a uniform resource identifier and easy access to parts of the URI.
In NoesisGUI, uniform resource identifiers (URIs) are used to identify and load resources like Images, Fonts and Dictionaries. Two kind of URIs are supported: absolute and relative.
Absolute URIs define a scheme preceding the path part. Paths beginning with a drive letter are also considered absolute (automatically normalized to a file scheme URI).
<Image Source="pack://application:,,,/Images/icon.png" />
<Image Source="file:///Images/icon.png" />
<Image Source="C:/Images/icon.png" />
<Image Source="http://www.noesisengine.com" />
A relative URI includes only the path.
<Image Source="Images/icon.png" />
Both absolute and relative URIs can have an optional assembly definition in the form of '/Assembly;component/' preceding the path.
<Image Source="pack://application:,,,/MyProject;component/Images/icon.png" />
<Image Source="/MyProject;component/Images/icon.png" />
By default, a relative URI is considered relative to the location of the XAML that contains the reference. If a leading slash is provided, however, the relative URI reference is then considered relative to the root of the application. For example, given the following project structure:
App.xaml
Page2.xaml
Folder/
+ Page1.xaml
+ Page2.xaml
If Page1.xaml contains a reference to 'Page2.xaml', it will point to 'Folder/Page2.xaml' as the reference is considered relative to the XAML. If it refers to '/Page2.xaml' or '/MyProject;component/Page2.xaml', it will point to the root 'Page2.xaml' as the reference is considered relative to the root of the application.
