WorkflowView.IServiceProvider.GetService Method

Gets the service of the specified type, if it is available.

Namespace:  System.Workflow.ComponentModel.Design
Assembly:  System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)
Object IServiceProvider.GetService(
	Type serviceType
)

Parameters

serviceType
Type: System.Type

The Type of the service to retrieve.

Return Value

Type: System.Object
An Object implementing the requested service, or a null reference (Nothing in Visual Basic) if the service cannot be resolved.

Implements

IServiceProvider.GetService(Type)

If the serviceType is CommandID this method will return a specific CommandID. For any other Type, GetService will return an Object that implements the requested service, or a null reference (Nothing) if the service cannot be resolved.

The following example uses the GetService method of the WorkflowView object to return an ISelectionService interface. If the service exists, EnsureVisible is called passing the currently selected activity using the PrimarySelection property of the ISelectionService object.

public void FindSelection()
{
    ISelectionService selectionService;
    selectionService = ((IServiceProvider)this.workflowView).GetService(typeof(ISelectionService))
        as ISelectionService;

    if (selectionService != null)
        this.workflowView.EnsureVisible(selectionService.PrimarySelection);
}
