注释

This method works with the DT_I8 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.

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 在数据流中使用数据类型.
