Gets the ulong value stored in the buffer column.
此 API 不符合 CLS 標準。

參數
- columnIndex
型別：System.Int32
The index of the column in the buffer row.
傳回值
型別：System.UInt64
The ulong value stored in the buffer column.
備註
This method works with the DT_UI8 data type in Integration Services.
If the buffer column DataType is not DT_UI8, the PipelineBuffer produces an UnsupportedBufferDataTypeException.
If the value of the column is null, the PipelineBuffer produces a ColumnIsNullException. You can check for null by first 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 使用資料流程中的資料類型.
