[C#]
public void CreateESRISpatialReferenceFromPRJFileExample()
{ //The
ISpatialReferenceFactory::CreateESRISpatialReferenceFromPRJFile
//method requires that you specify the path and filename of the PRJ
//file you wish to import to create a spatial reference from.

// use activator class with SpatialReferenceEnvironment
singleton Type factoryType =
Type.GetTypeFromProgID("esriGeometry.SpatialReferenceEnvironment");
System.Object obj = Activator.CreateInstance(factoryType);
ISpatialReferenceFactory3 spatialReferenceFactory = obj as
ISpatialReferenceFactory3;

ISpatialReference spatialReference =
spatialReferenceFactory.
CreateESRISpatialReferenceFromPRJFile("C:\\Program Files\\ArcGIS\\Coordinate
Systems\\Geographic Coordinate Systems\\World\\WGS 1984.prj");
}

Dim pSpatRefFact As

pSpatRef =
