Description

Use an element from the esriSRUnitType or esriSRUnit2Type enumerations as the unitType to create a particular predefined unit of measure.

[C#]

ISpatialReferenceFactory spatialReferenceFactory = new SpatialReferenceEnvironmentClass();
//Create the unit using the available units.  These can be
//found in the esriGeometry esriSRUnitType enumeration.
ILinearUnit linearUnit = spatialReferenceFactory.CreateUnit((int)esriSRUnitType.esriSRUnit_Foot) as ILinearUnit;

[Visual Basic .NET]

        Dim pSpatRefFact As ESRI.ArcGIS.Geometry.ISpatialReferenceFactory
        'Set the spatial reference factory to a new spatial reference environment
        pSpatRefFact = New ESRI.ArcGIS.Geometry.SpatialReferenceEnvironment

        Dim pUnit As ESRI.ArcGIS.Geometry.ILinearUnit

        'Create the unit using the available units.  These can be
        'found in the esriGeometry esriSRUnitType enumeration.

        pUnit = pSpatRefFact.CreateUnit(ESRI.ArcGIS.Geometry.esriSRUnitType.esriSRUnit_Foot)
