예제

다음 코드 예제에서는 GetService 메서드를 사용 하 여 디자이너 서비스에 액세스 하는 방법을 보여 줍니다.The following code example demonstrates the use of the GetService method to access designer services.

// This utility method connects the designer to various
// services it will use. 
private void InitializeServices()
{
    // Acquire a reference to DesignerActionService.
    this.actionService =
        GetService(typeof(DesignerActionService))
        as DesignerActionService;

    // Acquire a reference to DesignerActionUIService.
    this.actionUiService =
        GetService(typeof(DesignerActionUIService))
        as DesignerActionUIService;

    // Acquire a reference to IComponentChangeService.
    this.changeService =
        GetService(typeof(IComponentChangeService))
        as IComponentChangeService;

    // Hook the IComponentChangeService events.
    if (this.changeService != null)
    {
        this.changeService.ComponentChanged +=
            new ComponentChangedEventHandler(
            ChangeService_ComponentChanged);

            new ComponentEventHandler(
            changeService_ComponentRemoved);
    }

    // Acquire a reference to ISelectionService.
    this.selectionService =
        GetService(typeof(ISelectionService))
        as ISelectionService;
