Замечания
The IDTSComponentMetaData100 describes the layout of a data flow component. It contains the input and output objects, input and output columns, and the custom properties of the component. It also contains information that identifies the assembly, or DLL, that is created during design time and execution of the component. A reference to the metadata for a component is obtained by creating a new component, using the New method, or by accessing an existing component in the ComponentMetaDataCollection collection of the MainPipeClass class.
