Comentários

This method works with the following Integration Services data types:

If the value being assigned to the buffer column is not a string or the buffer column DataType is not a DT_STR, DT_WSTR, DT_TEXT, or DT_NTEXT, an UnsupportedBufferDataTypeException occurs.

If the value of the column is null, the PipelineBuffer produces a ColumnIsNullException. You can check for null by calling the IsNull method.

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 Trabalhando com tipos de dados no fluxo de dados.
