Hinweise

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 Verwenden von Datentypen im Datenfluss.
