| id | 层级视图项标识符。 |
| column | 列标识符。 |
| outStrings | 使用合并样本的值填充的列表（作为方法调用的结果）。 |
用于获取层级视图项的合并样本的值。
当 HierarchyFrameDataView 使用 ViewMode.MergeSamplesWithTheSameName 模式时，在相同层级视图级别上具有相同名称的多个样本会合并在一起，并表示为一项。在此情况下，GetItemColumnData 相应地表示汇总值。
通过 GetItemMergedSamplesColumnData 可以获取合并层级视图中各个样本的值。
结果会写入 outStrings 列表，后者在需要时会调整大小。
另请参阅：GetItemColumnData、GetItemMergedSamplesCount。
