Description

Use an element from the esriSRDatumType, esriSRDatum2Type, or esriSRDatum3Type enumerations as the datumType to create a particular predefined horizontal datum.

[C#] 
ISpatialReferenceFactory spatialReferenceFactory=new SpatialReferenceEnvironmentClass(); 
//Create the datum using the available datums. These can be 
//found in the esriGeometry esriSRDatumType enumeration. 
IDatum datum=spatialReferenceFactory.CreateDatum((int)esriSRDatumType.esriSRDatum_NAD1983);
[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 pDatum As IDatum 

'Create the datum using the available datums. These can be 
'found in the esriGeometry esriSRDatumType enumeration.
