參數
- columnIndex
The index of the column whose BufferColumn structure is retrieved.
傳回值
The BufferColumn structure of the specified PipelineBuffer column.
備註
The BufferColumn contains information about the data stored in a PipelineBuffer column. This information can be used to prevent exceptions that might occur when assigning data to the buffer column. For example, columns with a fixed length such as the DT_STR, DT_TEXT, DT_WSTR, and DT_BYTES data types will fail if the data length is greater than the MaxLength of the BufferColumn.
