ArcGIS.Core.Geometry Namespace > MapPointBuilder Class > MapPointBuilder Constructor : MapPointBuilder Constructor(SpatialReference)
(Optional) The SpatialReference. The default value is null.
Initializes an empty instance of the MapPointBuilder class. This method must be called on the MCT. Use QueuedTask.Run.
Syntax
public MapPointBuilder( 
   SpatialReference spatialReference
)
Public Function New( _
   Optional ByVal spatialReference As SpatialReference _
)

Parameters

spatialReference
(Optional) The SpatialReference. The default value is null.
Exceptions
ExceptionDescription
This method or property must be called within the lambda passed to QueuedTask.Run.
Example
// Use a builder convenience method or use a builder constructor.

MapPoint point1 = null;
MapPoint point2 = null;

// Builder constructors need to run on the MCT.
ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{
  using (MapPointBuilder mb = new MapPointBuilder(1.0, 2.0, 3.0))

    bool bhasID = mb.HasID;        // hasID = false

    // do something with the builder

    point1 = mb.ToGeometry();

    // change some of the builder properties
    mb.X = 11;
    mb.Y = 22;
    mb.HasZ = false;
    mb.HasM = true;
    mb.M = 44;
    // create another point
    point2 = mb.ToGeometry();

// Builder convenience methods don't need to run on the MCT.

hasM = point3.HasM;             // hasM = false
hasID = point3.HasID;           // hasID = false


// builderEx constructors don't need to run on the MCT.
MapPointBuilderEx builderEx = new MapPointBuilderEx(point1);
x = builderEx.X;              // x = 1.0
y = builderEx.Y;              // y = 2.0

hasID = builderEx.HasID;      // hasID = false
