Замечания
The SetDouble method assigns a 64 floating point double to the buffer column specified by the columnIndex parameter.
This method works with the DT_R8 data type in Integration Services.
If the DataType of the buffer column is not DT_R8, an UnsupportedBufferDataTypeException occurs.
For a complete list of Integration Services data types and the corresponding Get and Set methods of the PipelineBuffer class to use with each type, see Работа с типами данных в потоке данных.
