ITypeDescriptorFilterService定义了三个方法，以使设计器筛选器可以挂钩到站点化组件的元数据中并对其进行修改。
The ITypeDescriptorFilterService defines three methods that allow designer filters to hook into and modify a sited component's metadata.
一旦定义了数据集，您就可以选择在组件托盘上包含该数据集对象实例，用以将数据源快速映射到窗体设计器中的窗体控制。
Once the data set is defined, you have the option of including the data set object instance in your component tray for rapid data source mapping to form controls in your forms designer.
如果设计器希望为它正在设计的组件修改设计时环境可用的元数据，则可以通过实现IDesignerFilter来完成该工作。
Designers who want to modify the metadata available to the design-time environment for the component they are designing can do so by implementing IDesignerFilter.
