ESRI.ArcGIS.ADF.IMS.Carto Namespace > MapService Class : ServiceSpatialReference Property

Visual Basic (Declaration)

Visual Basic (Usage)

C#

The Spatial Reference properties of the ArcIMS Service for this Map.

Syntax

Visual Basic (Declaration)
Public ReadOnly Property ServiceSpatialReference As SpatialReference

Visual Basic (Usage)	Copy Code
`Dim instance As MapService Dim value As SpatialReference value = instance.ServiceSpatialReference`

C#
public SpatialReference ServiceSpatialReference {get;}

Example

The following example retrieves the SpatialReference object from an existing MapService object and prints its coordinate system ID or definition string.

// Retrieve SpatialReference from previously created MapService SpatialReference spatialRef = mapService.ServiceSpatialReference; // Make sure the SpatialReference exists if (spatialRef != null) { // Print coordinate system information if (spatialRef.CoordinateSystem is IDSpatialReferenceInfo) { IDSpatialReferenceInfo idInfo = (IDSpatialReferenceInfo)spatialRef.CoordinateSystem; lblSpatialRef.Text = "Coordinate system ID = " + idInfo.ID.ToString(); } else { DefinitionSpatialReferenceInfo defInfo = (DefinitionSpatialReferenceInfo)spatialRef.CoordinateSystem; lblSpatialRef.Text = "Coordinate system description = " + defInfo.Definition; } }

// Retrieve SpatialReference from previously created MapService 

SpatialReference spatialRef = mapService.ServiceSpatialReference; 

  

// Make sure the SpatialReference exists

End If

Remarks

May be null (Nothing) after initializing MapService if no coordinate system information has been added to the configuration file for the ArcIMS map service. Check that the object exists before accessing the spatial reference's properties.

This property, as with all properties of MapService, is read-only.
