ISite Interface
Provides functionality required by sites.
Assembly: System (in System.dll)
| Name | Description | |
|---|---|---|
![]() | Component | Gets the component associated with the ISite when implemented by a class. |
![]() | Container | Gets the IContainer associated with the ISite when implemented by a class. |
![]() | DesignMode | Determines whether the component is in design mode when implemented by a class. |
![]() | Name | Gets or sets the name of the component associated with the ISite when implemented by a class. |
| Name | Description | |
|---|---|---|
![]() | GetService(Type) | Gets the service object of the specified type.(Inherited from IServiceProvider.) |
Sites bind a Component to a Container and enable communication between them, as well as provide a way for the container to manage its components.
Sites can also serve as a repository for container-specific, per-component information, such as the component name. For more information about components, see Programming with Components.
Notes to Implementers:
To be a site, a class must implement the ISite interface.
The following example demonstrates the implementation of ISite, IComponent, and IContainer for use in a library container.
