## Detailed Description

The IMeasureUnitReader interface provides forward-only, read-only functionality for enumerating measurement units. A reference to an IMeasureUnitReader interface is returned from the GetMeasureUnits command. The initial position of the IMeasureUnitReader is prior to the first item. Thus, you must call ReadNext to begin accessing any data.
