CreateMultipoint(IEnumerable<MapPoint>,SpatialReference) Method
Example 

ArcGIS.Core.Geometry Namespace > MultipointBuilder Class > CreateMultipoint Method : CreateMultipoint(IEnumerable<MapPoint>,SpatialReference) Method
The set of points which will comprise the multipoint.
(Optional) The SpatialReference. The default value is null. If spatialReference is null, then the spatial reference will be inherited from points.
Convenience method to quickly create a Multipoint instance.
Syntax
Public Overloads Shared Function CreateMultipoint( _
   ByVal points As IEnumerable(Of MapPoint), _
   Optional ByVal spatialReference As SpatialReference _
) As Multipoint

Parameters

points
The set of points which will comprise the multipoint.
spatialReference
(Optional) The SpatialReference. The default value is null. If spatialReference is null, then the spatial reference will be inherited from points.

Return Value

Exceptions
ExceptionDescription
Incompatible spatial references.
points is null.
Example
// Use a builder convenience method or use a builder constructor.

List<MapPoint> list = new List<MapPoint>();
list.Add(MapPointBuilder.CreateMapPoint(1.0, 1.0));
list.Add(MapPointBuilder.CreateMapPoint(1.0, 2.0));
list.Add(MapPointBuilder.CreateMapPoint(2.0, 2.0));
list.Add(MapPointBuilder.CreateMapPoint(2.0, 1.0));

// Builder convenience methods don't need to run on the MCT.
Multipoint multiPoint = MultipointBuilder.CreateMultipoint(list);
int ptCount = multiPoint.PointCount;

// Builder constructors need to run on the MCT.
ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{
  using (MultipointBuilder mpb = new MultipointBuilder(list))
  {
    // do something with the builder

    Multipoint mPt = mpb.ToGeometry();

    ptCount = mpb.PointCount;
  }
});

// or use the builderEx constructors = don't need to run on the MCT.
MultipointBuilderEx builderEx = new MultipointBuilderEx(list);
multiPoint = builderEx.ToGeometry() as Multipoint;
ptCount = builderEx.PointCount;
