The index of the column in the PipelineBuffer row.
傳回值

備註
This method works with the DT_GUID data type in Integration Services.
If the value of the column is null, the PipelineBuffer produces a ColumnIsNullException. You should first check for null by calling the IsNull method before retrieving the Guid from the buffer column.
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.
