The SetSByte method assigns an sbyte to the buffer column specified by the columnIndex parameter.
This method works with the DT_I1 data type in Integration Services.
If the value being assigned to the buffer column is not an sbyte or the column data type is not DT_I1, 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 Working with Data Types in the Data Flow.
