Ejemplos

En el siguiente ejemplo se muestra cómo quitar una actividad de WorkflowDesignerLoader. Antes de que la última actividad secundaria en el flujo de trabajo se quite de WorkflowDesignerLoader, se quita primero de la colección del flujo de trabajo Activities.

public void RemoveLastChildActivity()
{
    IDesignerHost designerHost = (IDesignerHost)GetService(typeof(IDesignerHost));
    CompositeActivity rootActivity = designerHost.RootComponent as CompositeActivity;

    if (rootActivity.Activities.Count > 0)
    {
        Activity activityToRemove = rootActivity.Activities[rootActivity.Activities.Count - 1];
        rootActivity.Activities.Remove(activityToRemove);
        this.RemoveActivityFromDesigner(activityToRemove);
    }
}

Public Sub RemoveLastChildActivity()
    Dim designerHost As IDesignerHost = CType(GetService(GetType(IDesignerHost)), IDesignerHost)
    Dim rootActivity As CompositeActivity = CType(designerHost.RootComponent, CompositeActivity)

    If rootActivity.Activities.Count > 0 Then
        Dim activityToRemove As Activity = rootActivity.Activities(rootActivity.Activities.Count - 1)
        rootActivity.Activities.Remove(activityToRemove)
        Me.RemoveActivityFromDesigner(activityToRemove)
    End If
End Sub
