Notes
The GetRowCount method returns the number of rows contained in the buffer. If the buffer is an output buffer, which is one that is provided to the component by the PrimeOutput method, a Microsoft.SqlServer.Dts.HResults.DTS_E_BUFFERISPRIMEOUTPUT exception is thrown. This occurs because the IDTSBufferManager100 shuffles the rows in the full output buffer to downstream components in the graph, so there is no way to reliably report the number of rows in the output buffer.
