Comentários

This method works with the DT_R4 data type in Integration Services.

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

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.
