﻿ PointCount Property—ArcGIS Pro
ArcGIS Pro 2.6 API Reference Guide
PointCount Property (Multipart)
Example

 ArcGIS.Core.Geometry Namespace > Multipart Class : PointCount Property
Gets the count of all points in all parts for this instance.
Syntax
`public override int PointCount {get;}`
`Public Overrides ReadOnly Property PointCount As Integer`
Example
```// get the points as a readonly Collection
int numPts = polyline.PointCount;

// OR   get an enumeration of the points
IEnumerator<MapPoint> enumPts = polyline.Points.GetEnumerator();

// OR   get the point coordinates as a readonly list of Coordinate2D

// OR   get the point coordinates as a readonly list of Coordinate3D

// OR   get a subset of the collection as Coordinate2D using preallocated memory

IList<Coordinate2D> coordinate2Ds = new List<Coordinate2D>(10);   // allocate some space
ICollection<Coordinate2D> subsetCoordinates2D = coordinate2Ds;    // assign
pts.Copy2DCoordinatesToList(1, 2, ref subsetCoordinates2D);       // copy 2 elements from index 1 into the allocated list
// coordinate2Ds.Count = 2
// do something with the coordinate2Ds

// without allocating more space, obtain a different set of coordinates
pts.Copy2DCoordinatesToList(5, 9, ref subsetCoordinates2D);       // copy 9 elements from index 5 into the allocated list
// coordinate2Ds.Count = 9

// OR   get a subset of the collection as Coordinate3D using preallocated memory

IList<Coordinate3D> coordinate3Ds = new List<Coordinate3D>(15);   // allocate some space
ICollection<Coordinate3D> subsetCoordinates3D = coordinate3Ds;    // assign
pts.Copy3DCoordinatesToList(3, 5, ref subsetCoordinates3D);       // copy 5 elements from index 3 into the allocated list
// coordinate3Ds.Count = 5

// OR   get a subset of the collection as MapPoint using preallocated memory

IList<MapPoint> mapPoints = new List<MapPoint>(7);   // allocate some space
ICollection<MapPoint> subsetMapPoint = mapPoints;    // assign
pts.CopyPointsToList(1, 4, ref subsetMapPoint);      // copy 4 elements from index 1 into the allocated list
// mapPoints.Count = 4
