The SetUInt16 method assigns an unsigned 16-bit integer to the buffer column specified by the columnIndex parameter.
This method works with the DT_UI2 data type in Integration Services.
If the value being assigned to buffer column is not a 16-bit integer or the buffer column DataType is not a DT_UI2, 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.
