  型別：System. . :: . .Int32
  The index of the column in the buffer row.

傳回值

備註

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 使用資料流程中的資料類型.
