Hinweise

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 Verwenden von Datentypen im Datenfluss.
