Creating a predefined projected coordinate system

About creating a predefined projected coordinate system

The ISpatialReferenceFactory interface provides access for creating a projected coordinate system (PCS) in ArcGIS. You can return a single PCS with ISpatialReferenceFactory.CreateProjectedCoordinateSystem. Lists of the supported PCS are available in the esriSRProjCSType, esriSRProjCS2Type, esriSRProj3Type, and esriSRGeoCS4Type enumerations.
See the following code example:
[C#] 
private void CreateProjectedCoordinateSystem()
{
    // Set up the SpatialReferenceEnvironment.
    // SpatialReferenceEnvironment is a singleton object and needs to use the Activator class.

    Type t = Type.GetTypeFromProgID("esriGeometry.SpatialReferenceEnvironment");
    System.Object obj = Activator.CreateInstance(t);
    ISpatialReferenceFactory srFact = obj as ISpatialReferenceFactory;

    // Use the enumeration to create an instance of the predefined object.

    IProjectedCoordinateSystem projectedCS = srFact.CreateProjectedCoordinateSystem(
        (int)esriSRProjCSType.esriSRProjCS_NAD1983UTM_11N);
}
[VB.NET] 
Private Sub CreateProjectedReferenceSystem()
    ' Set up the SpatialReferenceEnvironment.
    ' SpatialReferenceEnvironment is a singleton object and needs to use the Activator class.
    
    Dim t As Type = Type.GetTypeFromProgID("esriGeometry.SpatialReferenceEnvironment")
    Dim obj As System.Object = Activator.CreateInstance(t)
    Dim srFact As ESRI.ArcGIS.Geometry.ISpatialReferenceFactory = obj
    
    ' Use the enumeration to create an instance of the predefined object.
    
    Dim projectedCS As IProjectedCoordinateSystem = srFact.CreateProjectedCoordinateSystem(esriSRProjCSType.esriSRProjCS_NAD1983UTM_11N)
End Sub
